+ * Message buffers build functionality on top of FreeRTOS stream buffers.
+ * Whereas stream buffers are used to send a continuous stream of data from one
+ * task or interrupt to another, message buffers are used to send variable
+ * length discrete messages from one task or interrupt to another. Their
+ * implementation is light weight, making them particularly suited for interrupt
+ * to task and core to core communication scenarios.
+ *
+ * ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
+ * implementation (so also the message buffer implementation, as message buffers
+ * are built on top of stream buffers) assumes there is only one task or
+ * interrupt that will write to the buffer (the writer), and only one task or
+ * interrupt that will read from the buffer (the reader). It is safe for the
+ * writer and reader to be different tasks or interrupts, but, unlike other
+ * FreeRTOS objects, it is not safe to have multiple different writers or
+ * multiple different readers. If there are to be multiple different writers
+ * then the application writer must place each call to a writing API function
+ * (such as xMessageBufferSend()) inside a critical section and set the send
+ * block time to 0. Likewise, if there are to be multiple different readers
+ * then the application writer must place each call to a reading API function
+ * (such as xMessageBufferRead()) inside a critical section and set the receive
+ * timeout to 0.
+ *
+ * Message buffers hold variable length messages. To enable that, when a
+ * message is written to the message buffer an additional sizeof( size_t ) bytes
+ * are also written to store the message's length (that happens internally, with
+ * the API function). sizeof( size_t ) is typically 4 bytes on a 32-bit
+ * architecture, so writing a 10 byte message to a message buffer on a 32-bit
+ * architecture will actually reduce the available space in the message buffer
+ * by 14 bytes (10 byte are used by the message, and 4 bytes to hold the length

+ * Create a new task and add it to the list of tasks that are ready to run.
+ *
+ * Internally, within the FreeRTOS implementation, tasks use two blocks of

+ * second block is used by the task as its stack. If a task is created using
+ * xTaskCreate() then both blocks of memory are automatically dynamically
+ * allocated inside the xTaskCreate() function. (see
+ * http://www.freertos.org/a00111.html). If a task is created using
+ * xTaskCreateStatic() then the application writer must provide the required
+ * memory. xTaskCreateStatic() therefore allows a task to be created without
+ * using any dynamic memory allocation.
+ *
+ * See xTaskCreateStatic() for a version that does not use any dynamic memory
+ * allocation.
+ *
+ * xTaskCreate() can only be used to create a task that has unrestricted

+ * is 16.

+ * variables the stack can hold - not the number of bytes. For example, if

+ * will be allocated for stack storage.
+ *
+ * @param pvParameters Pointer that will be used as the parameter for the task

+ *
+ * @param uxPriority The priority at which the task should run. Systems that

+ *
+ * Creates a new software timer instance, and returns a handle by which the
+ * created software timer can be referenced.
+ *
+ * Internally, within the FreeRTOS implementation, software timers use a block
+ * of memory, in which the timer data structure is stored. If a software timer
+ * is created using xTimerCreate() then the required memory is automatically
+ * dynamically allocated inside the xTimerCreate() function. (see
+ * http://www.freertos.org/a00111.html). If a software timer is created using
+ * xTimerCreateStatic() then the application writer must provide the memory that
+ * will get used by the software timer. xTimerCreateStatic() therefore allows a
+ * software timer to be created without using any dynamic memory allocation.
+ *
+ * Timers are created in the dormant state. The xTimerStart(), xTimerReset(),
+ * xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and
+ * xTimerChangePeriodFromISR() API functions can all be used to transition a
+ * timer into the active state.
+ *
+ * @param pcTimerName A text name that is assigned to the timer. This is done
+ * purely to assist debugging. The kernel itself only ever references a timer
+ * by its handle, and never by its name.
+ *
+ * @param xTimerPeriodInTicks The timer period. The time is defined in tick
+ * periods so the constant portTICK_PERIOD_MS can be used to convert a time that
+ * has been specified in milliseconds. For example, if the timer must expire
+ * after 100 ticks, then xTimerPeriodInTicks should be set to 100.
+ * Alternatively, if the timer must expire after 500ms, then xPeriod can be set
+ * to ( 500 / portTICK_PERIOD_MS ) provided configTICK_RATE_HZ is less than or
+ * equal to 1000.
+ *
+ * @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will
+ * expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter.
+ * If uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and
+ * enter the dormant state after it expires.
+ *
+ * @param pvTimerID An identifier that is assigned to the timer being created.
+ * Typically this would be used in the timer callback function to identify which
+ * timer expired when the same callback function is assigned to more than one
+ * timer.
+ *
+ * @param pxCallbackFunction The function to call when the timer expires.
+ * Callback functions must have the prototype defined by TimerCallbackFunction_t,
+ * which is "void vCallbackFunction( TimerHandle_t xTimer );".
+ *
+ * @return If the timer is successfully created then a handle to the newly
+ * created timer is returned. If the timer cannot be created (because either
+ * there is insufficient FreeRTOS heap remaining to allocate the timer
+ * structures, or the timer period was set to 0) then NULL is returned.

+ * BaseType_t xTimerPendFunctionCallFromISR( PendedFunction_t xFunctionToPend,
+ * void *pvParameter1,
+ * uint32_t ulParameter2,
+ * BaseType_t *pxHigherPriorityTaskWoken );
+ *
+ *
+ * Used from application interrupt service routines to defer the execution of a
+ * function to the RTOS daemon task (the timer service task, hence this function
+ * is implemented in timers.c and is prefixed with 'Timer').
+ *
+ * Ideally an interrupt service routine (ISR) is kept as short as possible, but
+ * sometimes an ISR either has a lot of processing to do, or needs to perform
+ * processing that is not deterministic. In these cases
+ * xTimerPendFunctionCallFromISR() can be used to defer processing of a function
+ * to the RTOS daemon task.
+ *
+ * A mechanism is provided that allows the interrupt to return directly to the
+ * task that will subsequently execute the pended callback function. This
+ * allows the callback function to execute contiguously in time with the
+ * interrupt - just as if the callback had executed in the interrupt itself.
+ *
+ * @param xFunctionToPend The function to execute from the timer service/
+ * daemon task. The function must conform to the PendedFunction_t
+ * prototype.
+ *
+ * @param pvParameter1 The value of the callback function's first parameter.
+ * The parameter has a void * type to allow it to be used to pass any type.
+ * For example, unsigned longs can be cast to a void *, or the void * can be
+ * used to point to a structure.
+ *
+ * @param ulParameter2 The value of the callback function's second parameter.
+ *
+ * @param pxHigherPriorityTaskWoken As mentioned above, calling this function
+ * will result in a message being sent to the timer daemon task. If the
+ * priority of the timer daemon task (which is set using
+ * configTIMER_TASK_PRIORITY in FreeRTOSConfig.h) is higher than the priority of
+ * the currently running task (the task the interrupt interrupted) then
+ * *pxHigherPriorityTaskWoken will be set to pdTRUE within
+ * xTimerPendFunctionCallFromISR(), indicating that a context switch should be
+ * requested before the interrupt exits. For that reason
+ * *pxHigherPriorityTaskWoken must be initialised to pdFALSE. See the
+ * example code below.
+ *
+ * @return pdPASS is returned if the message was successfully sent to the
+ * timer daemon task, otherwise pdFALSE is returned.
+ *
+ * Example usage:
+ * @verbatim
+ *
+ * // The callback function that will execute in the context of the daemon task.
+ * // Note callback functions must all use this same prototype.
+ * void vProcessInterface( void *pvParameter1, uint32_t ulParameter2 )
+ * {
+ * BaseType_t xInterfaceToService;
+ *
+ * // The interface that requires servicing is passed in the second
+ * // parameter. The first parameter is not used in this case.
+ * xInterfaceToService = ( BaseType_t ) ulParameter2;
+ *
+ * // ...Perform the processing here...
+ * }
+ *
+ * // An ISR that receives data packets from multiple interfaces
+ * void vAnISR( void )
+ * {
+ * BaseType_t xInterfaceToService, xHigherPriorityTaskWoken;
+ *
+ * // Query the hardware to determine which interface needs processing.
+ * xInterfaceToService = prvCheckInterfaces();
+ *
+ * // The actual processing is to be deferred to a task. Request the
+ * // vProcessInterface() callback function is executed, passing in the
+ * // number of the interface that needs processing. The interface to
+ * // service is passed in the second parameter. The first parameter is
+ * // not used in this case.
+ * xHigherPriorityTaskWoken = pdFALSE;
+ * xTimerPendFunctionCallFromISR( vProcessInterface, NULL, ( uint32_t ) xInterfaceToService, &xHigherPriorityTaskWoken );
+ *
+ * // If xHigherPriorityTaskWoken is now set to pdTRUE then a context
+ * // switch should be requested. The macro used is port specific and will
+ * // be either portYIELD_FROM_ISR() or portEND_SWITCHING_ISR() - refer to

+ 3) Calling an API function from within a critical section or when

+ * @brief CMSIS Cortex-M3 Device Peripheral Access Layer Header File.
+ * This file contains all the peripheral register's definitions, bits

+ * Medium-density and XL-density Plus devices.
+ *
+ * The file is the unique include file that the application programmer
+ * is using in the C source code, usually in main.c. This file contains:
+ * - Configuration section that allows to select:
+ * - The device used in the target application
+ * - To use or not the peripheral�s drivers in application code(i.e.
+ * code will be based on direct access to peripheral�s registers
+ * rather than drivers API), this option is controlled by
+ * "#define USE_STDPERIPH_DRIVER"
+ * - To change few application-specific parameters such as the HSE
+ * crystal frequency
+ * - Data structures and the address mapping for all peripherals
+ * - Peripheral's registers declarations and bits definition
+ * - Macros to access peripheral�s registers hardware

+ ******************************************************************************
+ * @file system_stm32l1xx.c
+ * @author MCD Application Team
+ * @version V1.3.3
+ * @date 20-April-2015
+ * @brief CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
+ * This file contains the system clock configuration for STM32L1xx Ultra
+ * Low Power devices, and is generated by the clock configuration
+ * tool "STM32L1xx_Clock_Configuration_V1.1.0.xls".
+ *
+ * 1. This file provides two functions and one global variable to be called from
+ * user application:
+ * - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
+ * and Divider factors, AHB/APBx prescalers and Flash settings),
+ * depending on the configuration made in the clock xls tool.
+ * This function is called at startup just after reset and
+ * before branch to main program. This call is made inside
+ * the "startup_stm32l1xx_xx.s" file.
+ *
+ * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+ * by the user application to setup the SysTick
+ * timer or configure other parameters.
+ *
+ * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+ * be called whenever the core clock is changed
+ * during program execution.
+ *
+ * 2. After each device reset the MSI (2.1 MHz Range) is used as system clock source.
+ * Then SystemInit() function is called, in "startup_stm32l1xx_xx.s" file, to
+ * configure the system clock before to branch to main program.
+ *
+ * 3. If the system clock source selected by user fails to startup, the SystemInit()
+ * function will do nothing and MSI still used as system clock source. User can
+ * add some code to deal with this issue inside the SetSysClock() function.
+ *
+ * 4. The default value of HSE crystal is set to 8MHz, refer to "HSE_VALUE" define
+ * in "stm32l1xx.h" file. When HSE is used as system clock source, directly or
+ * through PLL, and you are using different crystal you have to adapt the HSE
+ * value to your own configuration.
+ *
+ * 5. This file configures the system clock as follows:
+ *=============================================================================
+ * System Clock Configuration
+ *=============================================================================
+ * System Clock source | PLL(HSE)

+ ===============================================================================
+ I2C State Monitoring Functions
+ ===============================================================================
+ This I2C driver provides three different ways for I2C state monitoring
+ depending on the application requirements and constraints:
+
+
+ 1. Basic state monitoring (Using I2C_CheckEvent() function)
+ -----------------------------------------------------------
+ It compares the status registers (SR1 and SR2) content to a given event
+ (can be the combination of one or more flags).
+ It returns SUCCESS if the current status includes the given flags
+ and returns ERROR if one or more flags are missing in the current status.
+
+ - When to use
+ - This function is suitable for most applications as well as for startup
+ activity since the events are fully described in the product reference
+ manual (RM0038).
+ - It is also suitable for users who need to define their own events.
+
+ - Limitations
+ - If an error occurs (ie. error flags are set besides to the monitored
+ flags), the I2C_CheckEvent() function may return SUCCESS despite
+ the communication hold or corrupted real state.
+ In this case, it is advised to use error interrupts to monitor
+ the error events and handle them in the interrupt IRQ handler.
+
+ Note
+ For error management, it is advised to use the following functions:
+ - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
+ - I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
+ Where x is the peripheral instance (I2C1, I2C2 ...)
+ - I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the
+ I2Cx_ER_IRQHandler() function in order to determine which error occurred.
+ - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
+ and/or I2C_GenerateStop() in order to clear the error flag and source
+ and return to correct communciation status.
+
+
+ 2. Advanced state monitoring (Using the function I2C_GetLastEvent())
+ --------------------------------------------------------------------
+ Using the function I2C_GetLastEvent() which returns the image of both status
+ registers in a single word (uint32_t) (Status Register 2 value is shifted left
+ by 16 bits and concatenated to Status Register 1).
+
+ - When to use
+ - This function is suitable for the same applications above but it
+ allows to overcome the mentioned limitation of I2C_GetFlagStatus()
+ function.
+ - The returned value could be compared to events already defined in
+ the library (stm32l1xx_i2c.h) or to custom values defined by user.
+ This function is suitable when multiple flags are monitored at the
+ same time.
+ - At the opposite of I2C_CheckEvent() function, this function allows
+ user to choose when an event is accepted (when all events flags are
+ set and no other flags are set or just when the needed flags are set
+ like I2C_CheckEvent() function.
+
+ - Limitations
+ - User may need to define his own events.
+ - Same remark concerning the error management is applicable for this
+ function if user decides to check only regular communication flags
+ (and ignores error flags).
+
+
+ 3. Flag-based state monitoring (Using the function I2C_GetFlagStatus())
+ -----------------------------------------------------------------------
+
+ Using the function I2C_GetFlagStatus() which simply returns the status of
+ one single flag (ie. I2C_FLAG_RXNE ...).
+
+ - When to use
+ - This function could be used for specific applications or in debug
+ phase.
+ - It is suitable when only one flag checking is needed (most I2C
+ events are monitored through multiple flags).
+ - Limitations:
+ - When calling this function, the Status register is accessed.
+ Some flags are cleared when the status register is accessed.
+ So checking the status of one Flag, may clear other ones.
+ - Function may need to be called twice or more in order to monitor
+ one single event.
+
+ For detailed description of Events, please refer to section I2C_Events in
+ stm32l1xx_i2c.h file.

+ ##### Interrupts and flags management functions #####
+ ===============================================================================
+ [..] This section provides functions allowing to configure the ADC Interrupts
+ and get the status and clear flags and Interrupts pending bits.
+
+ [..] The ADC provide 4 Interrupts sources and 9 Flags which can be divided into
+ 3 groups:
+ *** Flags and Interrupts for ADC regular channels ***
+ =====================================================
+ [..]
+ (+)Flags :
+ (##) ADC_FLAG_OVR : Overrun detection when regular converted data are
+ lost.
+ (##) ADC_FLAG_EOC : Regular channel end of conversion + to indicate
+ (depending on EOCS bit, managed by ADC_EOCOnEachRegularChannelCmd() )
+ the end of :
+ (+++) a regular CHANNEL conversion.
+ (+++) sequence of regular GROUP conversions.
+
+
+ (##) ADC_FLAG_STRT: Regular channel start + to indicate when regular
+ CHANNEL conversion starts.
+ (##) ADC_FLAG_RCNR: Regular channel not ready + to indicate if a new
+ regular conversion can be launched.
+ (+)Interrupts :
+ (##) ADC_IT_OVR : specifies the interrupt source for Overrun detection
+ event.
+ (##) ADC_IT_EOC : specifies the interrupt source for Regular channel
+ end of conversion event.
+
+ *** Flags and Interrupts for ADC Injected channels ***
+ ======================================================
+ (+)Flags :
+ (##) ADC_FLAG_JEOC : Injected channel end of conversion+ to indicate at
+ the end of injected GROUP conversion.
+ (##) ADC_FLAG_JSTRT: Injected channel start + to indicate hardware when
+ injected GROUP conversion starts.
+ (##) ADC_FLAG_JCNR: Injected channel not ready + to indicate if a new
+ injected conversion can be launched.
+ (+)Interrupts
+ (##) ADC_IT_JEOC : specifies the interrupt source for Injected channel
+ end of conversion event.
+ *** General Flags and Interrupts for the ADC ***
+ ================================================
+ (+)Flags :
+ (##) ADC_FLAG_AWD: Analog watchdog + to indicate if the converted voltage
+ crosses the programmed thresholds values.
+ (##) ADC_FLAG_ADONS: ADC ON status + to indicate if the ADC is ready
+ to convert.
+ (+)Interrupts :
+ (##) ADC_IT_AWD : specifies the interrupt source for Analog watchdog
+ event.
+
+ [..] The user should identify which mode will be used in his application to
+ manage the ADC controller events: Polling mode or Interrupt mode.
+
+ [..] In the Polling Mode it is advised to use the following functions:
+ (+) ADC_GetFlagStatus() : to check if flags events occur.
+ (+) ADC_ClearFlag() : to clear the flags events.
+
+ [..] In the Interrupt Mode it is advised to use the following functions:
+ (+) ADC_ITConfig() : to enable or disable the interrupt source.
+ (+) ADC_GetITStatus() : to check if Interrupt occurs.
+ (+) ADC_ClearITPendingBit() : to clear the Interrupt pending Bit
+ (corresponding Flag).

+ to both encipher and decipher data using AES algorithm.
+ (#) The AES supports 4 operation modes:
+ (++) Encryption: It consumes 214 clock cycle when processing one 128-bit block
+ (++) Decryption: It consumes 214 clock cycle when processing one 128-bit block
+ (++) Key derivation for decryption: It consumes 80 clock cycle when processing one 128-bit block
+ (++) Key Derivation and decryption: It consumes 288 clock cycle when processing one 128-bit blobk
+ (#) Moreover 3 chaining modes are supported:
+ (++) Electronic codebook (ECB): Each plain text is encrypted/decrypted separately
+ (++) Cipher block chaining (CBC): Each block is XORed with the previous block
+ (++) Counter mode (CTR): A 128-bit counter is encrypted and then XORed with the
+ plain text to give the cipher text
+ (#) The AES peripheral supports data swapping: 1-bit, 8-bit, 16-bit and 32-bit.
+ (#) The AES peripheral supports write/read error handling with interrupt capability.
+ (#) Automatic data flow control with support of direct memory access (DMA) using
+ 2 channels, one for incoming data (DMA2 Channel5), and one for outcoming data
+ (DMA2 Channel3).

+ * @file stm32l1xx_comp.c
+ * @author MCD Application Team
+ * @version V1.3.1
+ * @date 20-April-2015
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the comparators (COMP1 and COMP2) peripheral:
+ * + Comparators configuration
+ * + Window mode control
+ * + Internal Reference Voltage (VREFINT) output
+ *
+ * @verbatim
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..] The device integrates two analog comparators COMP1 and COMP2:
+ (+) COMP1 is a fixed threshold (VREFINT) that shares the non inverting
+ input with the ADC channels.
+ (+) COMP2 is a rail-to-rail comparator whose the inverting input can be
+ selected among: DAC_OUT1, DAC_OUT2, 1/4 VREFINT, 1/2 VERFINT, 3/4
+ VREFINT, VREFINT, PB3 and whose the output can be redirected to
+ embedded timers: TIM2, TIM3, TIM4, TIM10.
+
+ (+) The two comparators COMP1 and COMP2 can be combined in window mode.
+
+ -@-
+ (#@) Comparator APB clock must be enabled to get write access
+ to comparator register using
+ RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE).
+
+ (#@) COMP1 comparator and ADC can't be used at the same time since
+ they share the same ADC switch matrix (analog switches).
+
+ (#@) When an I/O is used as comparator input, the corresponding GPIO
+ registers should be configured in analog mode.
+
+ (#@) Comparators outputs (CMP1OUT and CMP2OUT) are not mapped on
+ GPIO pin. They are only internal.
+ To get the comparator output level, use COMP_GetOutputLevel().
+
+ (#@) COMP1 and COMP2 outputs are internally connected to EXTI Line 21
+ and EXTI Line 22 respectively.
+ Interrupts can be used by configuring the EXTI Line using the
+ EXTI peripheral driver.
+
+ (#@) After enabling the comparator (COMP1 or COMP2), user should wait
+ for start-up time (tSTART) to get right output levels.
+ Please refer to product datasheet for more information on tSTART.
+
+ (#@) Comparators cannot be used to exit the device from Sleep or Stop
+ mode when the internal reference voltage is switched off using
+ the PWR_UltraLowPowerCmd() function (ULP bit in the PWR_CR register).

+ * @author MCD Application Team
+ * @version V1.3.1
+ * @date 20-April-2015
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the Digital-to-Analog Converter (DAC) peripheral:
+ * + DAC channels configuration: trigger, output buffer, data format
+ * + DMA management
+ * + Interrupts and flags management
+
+ * @verbatim
+ *
+ ===============================================================================
+ ##### DAC Peripheral features #####
+ ===============================================================================
+ [..] The device integrates two 12-bit Digital Analog Converters that can
+ be used independently or simultaneously (dual mode):
+ (#) DAC channel1 with DAC_OUT1 (PA4) as output.
+ (#) DAC channel2 with DAC_OUT2 (PA5) as output.
+
+ [..] Digital to Analog conversion can be non-triggered using DAC_Trigger_None
+ and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register using
+ DAC_SetChannel1Data()/DAC_SetChannel2Data.
+
+ [..] Digital to Analog conversion can be triggered by:
+ (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
+ The used pin (GPIOx_Pin9) must be configured in input mode.
+ (#) Timers TRGO: TIM2, TIM4, TIM6, TIM7 and TIM9
+ (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...).
+ The timer TRGO event should be selected using TIM_SelectOutputTrigger()
+ (#) Software using DAC_Trigger_Software.
+
+ [..] Each DAC channel integrates an output buffer that can be used to
+ reduce the output impedance, and to drive external loads directly
+ without having to add an external operational amplifier.
+ To enable, the output buffer use
+ DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
+
+ [..] Refer to the device datasheet for more details about output impedance
+ value with and without output buffer.
+
+ [..] Both DAC channels can be used to generate:
+ (#) Noise wave using DAC_WaveGeneration_Noise
+ (#) Triangle wave using DAC_WaveGeneration_Triangle
+
+ [..] Wave generation can be disabled using DAC_WaveGeneration_None.
+
+ [..] The DAC data format can be:
+ (#) 8-bit right alignment using DAC_Align_8b_R
+ (#) 12-bit left alignment using DAC_Align_12b_L
+ (#) 12-bit right alignment using DAC_Align_12b_R
+
+ [..] The analog output voltage on each DAC channel pin is determined
+ by the following equation: DAC_OUTx = VREF+ * DOR / 4095
+ with DOR is the Data Output Register.
+ VEF+ is the input voltage reference (refer to the device datasheet)
+ e.g. To set DAC_OUT1 to 0.7V, use
+ DAC_SetChannel1Data(DAC_Align_12b_R, 868);
+ Assuming that VREF+ = 3.3, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V.
+
+ [..] A DMA1 request can be generated when an external trigger (but not
+ a software trigger) occurs if DMA1 requests are enabled using
+ DAC_DMACmd()
+ [..] DMA1 requests are mapped as following:
+ (#) DAC channel1 is mapped on DMA1 channel3 which must be already
+ configured.
+ (#) DAC channel2 is mapped on DMA1 channel4 which must be already
+ configured.
+
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ (+) DAC APB clock must be enabled to get write access to DAC registers using
+ RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE)
+ (+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
+ (+) Configure the DAC channel using DAC_Init()
+ (+) Enable the DAC channel using DAC_Cmd()

+ * + Interrupts and flags management
+ *
+ * @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Enable The DMA controller clock using
+ RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE) function for DMA1 or
+ using RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA2, ENABLE) function for DMA2.
+ (#) Enable and configure the peripheral to be connected to the DMA channel
+ (except for internal SRAM / FLASH memories: no initialization is
+ necessary).
+ (#) For a given Channel, program the Source and Destination addresses,
+ the transfer Direction, the Buffer Size, the Peripheral and Memory
+ Incrementation mode and Data Size, the Circular or Normal mode,
+ the channel transfer Priority and the Memory-to-Memory transfer
+ mode (if needed) using the DMA_Init() function.
+ (#) Enable the NVIC and the corresponding interrupt(s) using the function
+ DMA_ITConfig() if you need to use DMA interrupts.
+ (#) Enable the DMA channel using the DMA_Cmd() function.
+ (#) Activate the needed channel Request using PPP_DMACmd() function for
+ any PPP peripheral except internal SRAM and FLASH (ie. SPI, USART ...)
+ The function allowing this operation is provided in each PPP peripheral
+ driver (ie. SPI_DMACmd for SPI peripheral).
+ (#) Optionally, you can configure the number of data to be transferred
+ when the channel is disabled (ie. after each Transfer Complete event
+ or when a Transfer Error occurs) using the function DMA_SetCurrDataCounter().
+ And you can get the number of remaining data to be transferred using
+ the function DMA_GetCurrDataCounter() at run time (when the DMA channel is
+ enabled and running).
+ (#) To control DMA events you can use one of the following two methods:
+ (##) Check on DMA channel flags using the function DMA_GetFlagStatus().
+ (##) Use DMA interrupts through the function DMA_ITConfig() at initialization
+ phase and DMA_GetITStatus() function into interrupt routines in
+ communication phase.
+ After checking on a flag you should clear it using DMA_ClearFlag()
+ function. And after checking on an interrupt event you should
+ clear it using DMA_ClearITPendingBit() function.

+ ==============================================================================
+ ##### EXTI features #####
+ ==============================================================================
+ [..] External interrupt/event lines are mapped as following:
+ (#) All available GPIO pins are connected to the 16 external
+ interrupt/event lines from EXTI0 to EXTI15.
+ (#) EXTI line 16 is connected to the PVD output.
+ (#) EXTI line 17 is connected to the RTC Alarm event.
+ (#) EXTI line 18 is connected to the USB Device FS wakeup event.
+ (#) EXTI line 19 is connected to the RTC Tamper and TimeStamp events.
+ (#) EXTI line 20 is connected to the RTC Wakeup event.
+ (#) EXTI line 21 is connected to the Comparator 1 wakeup event.
+ (#) EXTI line 22 is connected to the Comparator 2 wakeup event.
+ (#) EXTI line 23 is connected to the Comparator channel acquisition wakeup event.
+
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..] In order to use an I/O pin as an external interrupt source, follow
+ steps below:
+ (#) Configure the I/O in input mode using GPIO_Init()
+ (#) Select the input source pin for the EXTI line using
+ SYSCFG_EXTILineConfig()
+ (#) Select the mode(interrupt, event) and configure the trigger
+ selection (Rising, falling or both) using EXTI_Init()
+ (#) Configure NVIC IRQ channel mapped to the EXTI line using NVIC_Init()
+ [..]
+ (@) SYSCFG APB clock must be enabled to get write access to SYSCFG_EXTICRx
+ registers using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);

+
+ [..] The FLASH_Option Bytes Programming_functions, includes the following functions:
+ (+) void FLASH_OB_Unlock(void);
+ (+) void FLASH_OB_Lock(void);
+ (+) void FLASH_OB_Launch(void);
+ (+) FLASH_Status FLASH_OB_WRPConfig(uint32_t OB_WRP, FunctionalState NewState);

+ (+) FLASH_Status FLASH_OB_RDPConfig(uint8_t OB_RDP);
+ (+) FLASH_Status FLASH_OB_PCROPConfig(uint32_t OB_WRP, FunctionalState NewState);
+ (+) FLASH_Status FLASH_OB_PCROP1Config(uint32_t OB_WRP1, FunctionalState NewState);
+ (+) FLASH_Status FLASH_OB_PCROPSelectionConfig(uint16_t OB_PcROP);
+ (+) FLASH_Status FLASH_OB_UserConfig(uint8_t OB_IWDG, uint8_t OB_STOP, uint8_t OB_STDBY);
+ (+) FLASH_Status FLASH_OB_BORConfig(uint8_t OB_BOR);
+ (+) uint8_t FLASH_OB_GetUser(void);
+ (+) uint32_t FLASH_OB_GetWRP(void);
+ (+) uint32_t FLASH_OB_GetWRP1(void);
+ (+) uint32_t FLASH_OB_GetWRP2(void);
+ (+) FlagStatus FLASH_OB_GetRDP(void);
+ (+) FlagStatus FLASH_OB_GetSPRMOD(void);
+ (+) uint8_t FLASH_OB_GetBOR(void);
+ (+) FLASH_Status FLASH_OB_BootConfig(uint16_t OB_BOOT);
+
+ [..] Any operation of erase or program should follow these steps:
+ (#) Call the FLASH_OB_Unlock() function to enable the Flash option control
+ register access.
+ (#) Call one or several functions to program the desired option bytes.
+ (++) void FLASH_OB_WRPConfig(uint32_t OB_WRP, FunctionalState NewState) => to Enable/Disable
+ the desired sector write protection.
+ (++) void FLASH_OB_RDPConfig(uint8_t OB_RDP) => to set the desired read Protection Level.
+ (++) void FLASH_OB_UserConfig(uint8_t OB_IWDG, uint8_t OB_STOP, uint8_t OB_STDBY) => to configure
+ the user option Bytes: IWDG, STOP and the Standby.
+ (++) void FLASH_OB_BORConfig(uint8_t OB_BOR) => to Set the BOR level.
+ (#) Once all needed option bytes to be programmed are correctly written, call the
+ FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
+ (#) Call the FLASH_OB_Lock() to disable the Flash option control register access (recommended
+ to protect the option Bytes against possible unwanted operations).
+
+ [..] Proprietary code Read Out Protection (PcROP):
+ (#) The PcROP sector is selected by using the same option bytes as the Write
+ protection (nWRPi bits). As a result, these 2 options are exclusive each other.
+ (#) In order to activate the PcROP (change the function of the nWRPi option bits),
+ the SPRMOD option bit must be activated.
+ (#) The active value of nWRPi bits is inverted when PCROP mode is active, this
+ means: if SPRMOD = 1 and nWRPi = 1 (default value), then the user sector "i"
+ is read/write protected.
+ (#) To activate PCROP mode for Flash sector(s), you need to follow the sequence below:
+ (++) For sector(s) within the first 128KB of the Flash, use this function
+ FLASH_OB_PCROPConfig(OB_WRP_Pagesxxx, ENABLE)
+ (++) For sector(s) within the second 128KB of the Flash, use this function
+ FLASH_OB_PCROP1Config(OB_WRP_Pagesxxx, ENABLE)
+ (++) Activate the PCROP mode using FLASH_OB_PCROPSelectionConfig(OB_PcROP_Enable) function
+ (#) PcROP is available only in STM32L1XX_MDP devices

+ * @author MCD Application Team
+ * @version V1.3.1
+ * @date 20-April-2015
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the GPIO peripheral:
+ * + Initialization and Configuration
+ * + GPIO Read and Write
+ * + GPIO Alternate functions configuration
+ *
+ * @verbatim
+ ===========================================================================
+ ##### How to use this driver #####
+ ===========================================================================
+ [..]
+ (#) Enable the GPIO AHB clock using RCC_AHBPeriphClockCmd()
+ (#) Configure the GPIO pin(s) using GPIO_Init()
+ Four possible configuration are available for each pin:
+ (++) Input: Floating, Pull-up, Pull-down.
+ (++) Output: Push-Pull (Pull-up, Pull-down or no Pull)
+ Open Drain (Pull-up, Pull-down or no Pull).
+ In output mode, the speed is configurable: Very Low, Low,
+ Medium or High.
+ (++) Alternate Function: Push-Pull (Pull-up, Pull-down or no Pull)
+ Open Drain (Pull-up, Pull-down or no Pull).
+ (++) Analog: required mode when a pin is to be used as ADC channel,
+ DAC output or comparator input.
+ (#) Peripherals alternate function:
+ (++) For ADC, DAC and comparators, configure the desired pin in
+ analog mode using GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN
+ (++) For other peripherals (TIM, USART...):
+ (+++) Connect the pin to the desired peripherals' Alternate
+ Function (AF) using GPIO_PinAFConfig() function.
+ (+++) Configure the desired pin in alternate function mode using
+ GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
+ (+++) Select the type, pull-up/pull-down and output speed via
+ GPIO_PuPd, GPIO_OType and GPIO_Speed members.
+ (+++) Call GPIO_Init() function.
+ (#) To get the level of a pin configured in input mode use GPIO_ReadInputDataBit()
+ (#) To set/reset the level of a pin configured in output mode use
+ GPIO_SetBits()/GPIO_ResetBits()
+ (#) During and just after reset, the alternate functions are not
+ active and the GPIO pins are configured in input floating mode
+ (except JTAG pins).
+ (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as
+ general-purpose (PC14 and PC15, respectively) when the LSE
+ oscillator is off. The LSE has priority over the GPIO function.
+ (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
+ general-purpose PH0 and PH1, respectively, when the HSE
+ oscillator is off. The HSE has priority over the GPIO function.

+ * @brief Interrupts, events and flags management functions
+ *
+@verbatim
+ ===============================================================================
+ ##### Interrupts, events and flags management functions #####
+ ===============================================================================
+ [..] This section provides functions allowing to configure the I2C Interrupts
+ sources and check or clear the flags or pending bits status.
+ The user should identify which mode will be used in his application to manage
+ the communication: Polling mode, Interrupt mode or DMA mode.
+
+
+ ##### I2C State Monitoring Functions #####
+ ===============================================================================
+ [..]This I2C driver provides three different ways for I2C state monitoring
+ depending on the application requirements and constraints:
+
+
+ ***. Basic state monitoring (Using I2C_CheckEvent() function) ***
+ -----------------------------------------------------------------
+ [..]It compares the status registers (SR1 and SR2) content to a given event
+ (can be the combination of one or more flags).
+ It returns SUCCESS if the current status includes the given flags
+ and returns ERROR if one or more flags are missing in the current status.
+
+ (+) When to use
+ (++) This function is suitable for most applications as well as for
+ startup activity since the events are fully described in the product
+ reference manual (RM0038).
+ (++) It is also suitable for users who need to define their own events.
+ (+) Limitations
+ (++) If an error occurs (ie. error flags are set besides to the monitored
+ flags), the I2C_CheckEvent() function may return SUCCESS despite
+ the communication hold or corrupted real state.
+ In this case, it is advised to use error interrupts to monitor
+ the error events and handle them in the interrupt IRQ handler.
+ -@@- For error management, it is advised to use the following functions:
+ (+@@) I2C_ITConfig() to configure and enable the error interrupts
+ (I2C_IT_ERR).
+ (+@@) I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
+ Where x is the peripheral instance (I2C1, I2C2 ...).
+ (+@@) I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the
+ I2Cx_ER_IRQHandler() function in order to determine which error occurred.
+ (+@@) I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
+ and/or I2C_GenerateStop() in order to clear the error flag and source
+ and return to correct communication status.
+
+ *** Advanced state monitoring (Using the function I2C_GetLastEvent()) ***
+ -------------------------------------------------------------------------
+ [..] Using the function I2C_GetLastEvent() which returns the image of both status
+ registers in a single word (uint32_t) (Status Register 2 value is shifted left
+ by 16 bits and concatenated to Status Register 1).
+
+ (+) When to use
+ (++) This function is suitable for the same applications above but it
+ allows to overcome the mentioned limitation of I2C_GetFlagStatus()
+ function.
+ (++) The returned value could be compared to events already defined in
+ the library (stm32l1xx_i2c.h) or to custom values defined by user.
+ This function is suitable when multiple flags are monitored at the
+ same time.
+ (++) At the opposite of I2C_CheckEvent() function, this function allows
+ user to choose when an event is accepted (when all events flags are
+ set and no other flags are set or just when the needed flags are set
+ like I2C_CheckEvent() function.
+
+ (+) Limitations
+ (++) User may need to define his own events.
+ (++) Same remark concerning the error management is applicable for this
+ function if user decides to check only regular communication flags
+ (and ignores error flags).
+
+
+ *** Flag-based state monitoring (Using the function I2C_GetFlagStatus()) ***
+ ----------------------------------------------------------------------------
+ [..] Using the function I2C_GetFlagStatus() which simply returns the status of
+ one single flag (ie. I2C_FLAG_RXNE ...).
+ (+) When to use
+ (++) This function could be used for specific applications or in debug
+ phase.
+ (++) It is suitable when only one flag checking is needed (most I2C
+ events are monitored through multiple flags).
+ (+) Limitations:
+ (++) When calling this function, the Status register is accessed.
+ Some flags are cleared when the status register is accessed.
+ So checking the status of one Flag, may clear other ones.
+ (++) Function may need to be called twice or more in order to monitor
+ one single event.
+
+ [..] For detailed description of Events, please refer to section I2C_Events in
+ stm32l1xx_i2c.h file.

+ * @author MCD Application Team
+ * @version V1.3.1
+ * @date 20-April-2015
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the Independent watchdog (IWDG) peripheral:
+ * + Prescaler and Counter configuration
+ * + IWDG activation
+ * + Flag management
+ *
+ * @verbatim
+ *
+ ==============================================================================
+ ##### IWDG features #####
+ ==============================================================================
+ [..] The IWDG can be started by either software or hardware (configurable
+ through option byte).
+
+ [..] The IWDG is clocked by its own dedicated low-speed clock (LSI) and
+ thus stays active even if the main clock fails.
+ Once the IWDG is started, the LSI is forced ON and cannot be disabled
+ (LSI cannot be disabled too), and the counter starts counting down from
+ the reset value of 0xFFF. When it reaches the end of count value (0x000)
+ a system reset is generated.
+ The IWDG counter should be reloaded at regular intervals to prevent
+ an MCU reset.
+
+ [..] The IWDG is implemented in the VDD voltage domain that is still functional
+ in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
+
+ [..] IWDGRST flag in RCC_CSR register can be used to inform when a IWDG
+ reset occurs.
+
+ [..] Min-max timeout value @37KHz (LSI): ~108us / ~28.3s
+ The IWDG timeout may vary due to LSI frequency dispersion. STM32L1xx
+ devices provide the capability to measure the LSI frequency (LSI clock
+ connected internally to TIM10 CH1 input capture). The measured value
+ can be used to have an IWDG timeout with an acceptable accuracy.
+ For more information, please refer to the STM32L1xx Reference manual.
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Enable write access to IWDG_PR and IWDG_RLR registers using
+ IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable) function.
+ (#) Configure the IWDG prescaler using IWDG_SetPrescaler() function.
+
+ (#) Configure the IWDG counter value using IWDG_SetReload() function.
+ This value will be loaded in the IWDG counter each time the counter
+ is reloaded, then the IWDG will start counting down from this value.
+
+ (#) Start the IWDG using IWDG_Enable() function, when the IWDG is used
+ in software mode (no need to enable the LSI, it will be enabled
+ by hardware).
+
+ (#) Then the application program must reload the IWDG counter at regular
+ intervals during normal operation to prevent an MCU reset, using
+ IWDG_ReloadCounter() function.

+ [..] Using its double buffer memory the LCD controller ensures the coherency
+ of the displayed information without having to use interrupts to control
+ LCD_RAM modification.
+
+ [..] The application software can access the first buffer level (LCD_RAM) through
+ the APB interface. Once it has modified the LCD_RAM, it sets the UDR flag
+ in the LCD_SR register using the LCD_UpdateDisplayRequest() function.
+
+ [..] This UDR flag (update display request) requests the updated information
+ to be moved into the second buffer level (LCD_DISPLAY).
+
+ [..] This operation is done synchronously with the frame (at the beginning of
+ the next frame), until the update is completed, the LCD_RAM is write
+ protected and the UDR flag stays high.
+
+ [..] Once the update is completed another flag (UDD - Update Display Done) is
+ set and generates an interrupt if the UDDIE bit in the LCD_FCR register
+ is set.
+
+ [..] The time it takes to update LCD_DISPLAY is, in the worst case, one odd
+ and one even frame.
+
+ [..] The update will not occur (UDR = 1 and UDD = 0) until the display is
+ enabled (LCDEN = 1).

+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the operational amplifiers (opamp) peripheral:
+ * + Initialization and configuration
+ * + Calibration management
+ *
+ * @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..] The device integrates three independent rail-to-rail operational amplifiers
+ OPAMP1, OPAMP2 and OPAMP3:
+ (+) Internal connections to the ADC.
+ (+) Internal connections to the DAC.
+ (+) Internal connection to COMP1 (only OPAMP3).
+ (+) Internal connection for unity gain (voltage follower) configuration.
+ (+) Calibration capability.
+ (+) Selectable gain-bandwidth (2MHz in normal mode, 500KHz in low power mode).
+ [..]
+ (#) COMP AHB clock must be enabled to get write access
+ to OPAMP registers using
+ (#) RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE)
+
+ (#) Configure the corresponding GPIO to OPAMPx INP, OPAMPx_INN (if used)
+ and OPAMPx_OUT in analog mode.
+
+ (#) Configure (close/open) the OPAMP switches using OPAMP_SwitchCmd()
+
+ (#) Enable the OPAMP peripheral using OPAMP_Cmd()
+
+ -@- In order to use OPAMP outputs as ADC inputs, the opamps must be enabled
+ and the ADC must use the OPAMP output channel number:
+ (+@) OPAMP1 output is connected to ADC channel 3.
+ (+@) OPAMP2 output is connected to ADC channel 8.
+ (+@) OPAMP3 output is connected to ADC channel 13 (SW1 switch must be closed).

+ (+) Sleep mode: Cortex-M3 core stopped, peripherals kept running.
+ (+) Low power sleep mode: Cortex-M3 core stopped, limited clock frequency,
+ limited number of peripherals running, regulator in low power mode.
+ (+) Stop mode: all clocks are stopped, regulator running, regulator in low power mode.
+ (+) Standby mode: VCORE domain powered off.
+
+ *** Low power run mode (LP run) ***
+ ===================================
+ [..]
+ (+) Entry:
+ (++) Decrease the system frequency.
+ (++) The regulator is forced in low power mode using the PWR_EnterLowPowerRunMode()
+ function.
+ (+) Exit:
+ (++) The regulator is forced in Main regulator mode sing the PWR_EnterLowPowerRunMode()
+ function.

+ ==================
+ [..]
+ (+) Entry:
+ (++) The Sleep mode is entered by using the PWR_EnterSleepMode(PWR_Regulator_ON,)
+ function with regulator ON.
+ (+) Exit:
+ (++) Any peripheral interrupt acknowledged by the nested vectored interrupt
+ controller (NVIC) can wake up the device from Sleep mode.

+ (++) The Flash memory must be switched off by using the FLASH_SLEEPPowerDownCmd()
+ function.

+ *** Auto-wakeup (AWU) from low-power mode ***
+ =============================================
+ [..]The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC

+ without depending on an external interrupt (Auto-wakeup mode).
+
+ (+) RTC auto-wakeup (AWU) from the Stop mode
+ (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to:
+ (+++) Configure the EXTI Line 17 to be sensitive to rising edges (Interrupt
+ or Event modes) using the EXTI_Init() function.
+ (+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function
+ (+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
+ and RTC_AlarmCmd() functions.
+ (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
+ is necessary to:
+ (+++) Configure the EXTI Line 19 to be sensitive to rising edges (Interrupt
+ or Event modes) using the EXTI_Init() function.
+ (+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
+ function.
+ (+++) Configure the RTC to detect the tamper or time stamp event using the
+ RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
+ functions.
+ (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to:
+ (+++) Configure the EXTI Line 20 to be sensitive to rising edges (Interrupt
+ or Event modes) using the EXTI_Init() function.
+ (+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function.
+ (+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
+ RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
+
+ (+) RTC auto-wakeup (AWU) from the Standby mode
+ (++) To wake up from the Standby mode with an RTC alarm event, it is necessary to:
+ (+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function.
+ (+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
+ and RTC_AlarmCmd() functions.
+ (++) To wake up from the Standby mode with an RTC Tamper or time stamp event, it
+ is necessary to:
+ (+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
+ function.
+ (+++) Configure the RTC to detect the tamper or time stamp event using the
+ RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
+ functions.
+ (++) To wake up from the Standby mode with an RTC WakeUp event, it is necessary to:
+ (+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function
+ (+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
+ RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
+
+ (+) Comparator auto-wakeup (AWU) from the Stop mode
+ (++) To wake up from the Stop mode with an comparator 1 or comparator 2 wakeup
+ event, it is necessary to:
+ (+++) Configure the EXTI Line 21 for comparator 1 or EXTI Line 22 for comparator 2
+ to be sensitive to to the selected edges (falling, rising or falling
+ and rising) (Interrupt or Event modes) using the EXTI_Init() function.
+ (+++) Configure the comparator to generate the event.

+ (#) The clock for all peripherals is switched off, except the SRAM and
+ FLASH.
+ (#) All GPIOs are in input floating state, except the JTAG pins which
+ are assigned to be used for debug purpose.
+ [..] Once the device started from reset, the user application has to:
+ (#) Configure the clock source to be used to drive the System clock
+ (if the application needs higher frequency/performance)
+ (#) Configure the System clock frequency and Flash settings
+ (#) Configure the AHB and APB busses prescalers
+ (#) Enable the clock for the peripheral(s) to be used

+ ##### System, AHB and APB busses clocks configuration functions #####
+ ===============================================================================
+ [..] This section provide functions allowing to configure the System, AHB,
+ APB1 and APB2 busses clocks.
+ (#) Several clock sources can be used to drive the System clock (SYSCLK):
+ MSI, HSI, HSE and PLL.
+ The AHB clock (HCLK) is derived from System clock through configurable
+ prescaler and used to clock the CPU, memory and peripherals mapped
+ on AHB bus (DMA and GPIO).APB1 (PCLK1) and APB2 (PCLK2) clocks are
+ derived from AHB clock through configurable prescalers and used to
+ clock the peripherals mapped on these busses. You can use
+ "RCC_GetClocksFreq()" function to retrieve the frequencies of these
+ clocks.
+
+ -@- All the peripheral clocks are derived from the System clock (SYSCLK)
+ except:
+ (+@) The USB 48 MHz clock which is derived from the PLL VCO clock.
+ (+@) The ADC clock which is always the HSI clock. A divider by 1, 2
+ or 4 allows to adapt the clock frequency to the device operating
+ conditions.
+ (+@) The RTC/LCD clock which is derived from the LSE, LSI or 1 MHz
+ HSE_RTC (HSE divided by a programmable prescaler).
+ The System clock (SYSCLK) frequency must be higher or equal to
+ the RTC/LCD clock frequency.
+ (+@) IWDG clock which is always the LSI clock.
+
+ (#) The maximum frequency of the SYSCLK, HCLK, PCLK1 and PCLK2 is 32 MHz.
+ Depending on the device voltage range, the maximum frequency should
+ be adapted accordingly:
+
+ +----------------------------------------------------------------+
+ | Wait states | HCLK clock frequency (MHz) |
+ | |------------------------------------------------|
+ | (Latency) | voltage range | voltage range |
+ | | 1.65 V - 3.6 V | 2.0 V - 3.6 V |
+ | |----------------|---------------|---------------|
+ | | VCORE = 1.2 V | VCORE = 1.5 V | VCORE = 1.8 V |
+ |-------------- |----------------|---------------|---------------|
+ |0WS(1CPU cycle)|0 < HCLK <= 2 |0 < HCLK <= 8 |0 < HCLK <= 16 |
+ |---------------|----------------|---------------|---------------|
+ |1WS(2CPU cycle)|2 < HCLK <= 4 |8 < HCLK <= 16 |16 < HCLK <= 32|
+ +----------------------------------------------------------------+
+
+ (#) After reset, the System clock source is the MSI (2 MHz) with 0 WS,
+ Flash 32-bit access is enabled and prefetch is disabled.
+ [..] It is recommended to use the following software sequences to tune the
+ number of wait states needed to access the Flash memory with the CPU
+ frequency (HCLK).
+ (+) Increasing the CPU frequency (in the same voltage range)
+ (+) Program the Flash 64-bit access, using "FLASH_ReadAccess64Cmd(ENABLE)"
+ function
+ (+) Check that 64-bit access is taken into account by reading FLASH_ACR
+ (+) Program Flash WS to 1, using "FLASH_SetLatency(FLASH_Latency_1)"
+ function
+ (+) Check that the new number of WS is taken into account by reading
+ FLASH_ACR
+ (+) Modify the CPU clock source, using "RCC_SYSCLKConfig()" function
+ (+) If needed, modify the CPU clock prescaler by using "RCC_HCLKConfig()"
+ function
+ (+) Check that the new CPU clock source is taken into account by reading
+ the clock source status, using "RCC_GetSYSCLKSource()" function
+ (+) Decreasing the CPU frequency (in the same voltage range)
+ (+) Modify the CPU clock source, using "RCC_SYSCLKConfig()" function
+ (+) If needed, modify the CPU clock prescaler by using "RCC_HCLKConfig()"
+ function
+ (+) Check that the new CPU clock source is taken into account by reading
+ the clock source status, using "RCC_GetSYSCLKSource()" function
+ (+) Program the new number of WS, using "FLASH_SetLatency()" function
+ (+) Check that the new number of WS is taken into account by reading
+ FLASH_ACR
+ (+) Enable the Flash 32-bit access, using "FLASH_ReadAccess64Cmd(DISABLE)"
+ function
+ (+) Check that 32-bit access is taken into account by reading FLASH_ACR

+
+ ===============================================================================
+ ##### RTC Domain Reset #####
+ ===============================================================================
+ [..] After power-on reset, the RTC domain (RTC clock source configuration,
+ RTC registers and RTC Backup data registers) is reset. You can also
+ reset this domain by software using the RCC_RTCResetCmd() function.
+
+ ##### RTC Operating Condition #####
+ ===============================================================================
+ [..] As long as the supply voltage remains in the operating range,
+ the RTC never stops, regardless of the device status (Run mode,
+ low power modes or under reset).
+
+ ##### RTC Domain Access #####
+ ===============================================================================
+ [..] After reset, the RTC domain (RTC clock source configuration,
+ RTC registers and RTC Backup data registers) are protected against
+ possible stray write accesses.
+ [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
+ (+) Enable the Power Controller (PWR) APB1 interface clock using the
+ RCC_APB1PeriphClockCmd() function.
+ (+) Enable access to RTC domain using the PWR_RTCAccessCmd() function.
+ (+) Select the RTC clock source using the RCC_RTCCLKConfig() function.
+ (+) Enable RTC Clock using the RCC_RTCCLKCmd() function.
+
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ (+) Enable the RTC domain access (see description in the section above)
+ (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and
+ RTC hour format using the RTC_Init() function.
+ ***Time and Date configuration ***
+ ==================================
+ [..]
+ (+) To configure the RTC Calendar (Time and Date) use the RTC_SetTime()
+ and RTC_SetDate() functions.
+ (+) To read the RTC Calendar, use the RTC_GetTime() and RTC_GetDate()
+ functions.
+ (+) To read the RTC subsecond, use the RTC_GetSubSecond() function.
+ (+) Use the RTC_DayLightSavingConfig() function to add or sub one
+ hour to the RTC Calendar.
+
+ ***Alarm configuration ***
+ ==========================
+ [..]
+ (+) To configure the RTC Alarm use the RTC_SetAlarm() function.
+ (+) Enable the selected RTC Alarm using the RTC_AlarmCmd() function
+ (+) To read the RTC Alarm, use the RTC_GetAlarm() function.
+ (+) To read the RTC alarm SubSecond, use the RTC_GetAlarmSubSecond() function.
+
+ ***RTC Wakeup configuration ***
+ ===============================
+ [..]
+ (+) Configure the RTC Wakeup Clock source use the RTC_WakeUpClockConfig()
+ function.
+ (+) Configure the RTC WakeUp Counter using the RTC_SetWakeUpCounter()
+ function.
+ (+) Enable the RTC WakeUp using the RTC_WakeUpCmd() function
+ (+) To read the RTC WakeUp Counter register, use the RTC_GetWakeUpCounter()
+ function.
+
+ ***Outputs configuration ***
+ ============================
+ [..] The RTC has 2 different outputs:
+ (+) AFO_ALARM: this output is used to manage the RTC Alarm A, Alarm B
+ and WaKeUp signals.
+ To output the selected RTC signal on RTC_AF1 pin, use the
+ RTC_OutputConfig() function.
+ (+) AFO_CALIB: this output is 512Hz signal or 1Hz.
+ To output the RTC Clock on RTC_AF1 pin, use the RTC_CalibOutputCmd()
+ function.
+
+ ***Smooth digital Calibration configuration ***
+ ===============================================
+ [..]
+ (+) Configure the RTC Original Digital Calibration Value and the corresponding
+ calibration cycle period (32s,16s and 8s) using the RTC_SmoothCalibConfig()
+ function.
+
+ ***Coarse digital Calibration configuration ***
+ ===============================================
+ [..]
+ (+) Configure the RTC Coarse Calibration Value and the corresponding
+ sign using the RTC_CoarseCalibConfig() function.
+ (+) Enable the RTC Coarse Calibration using the RTC_CoarseCalibCmd()
+ function.
+
+ ***TimeStamp configuration ***
+ ==============================
+ [..]
+ (+) Configure the RTC_AF1 trigger and enables the RTC TimeStamp
+ using the RTC_TimeStampCmd() function.
+ (+) To read the RTC TimeStamp Time and Date register, use the
+ RTC_GetTimeStamp() function.
+ (+) To read the RTC TimeStamp SubSecond register, use the
+ RTC_GetTimeStampSubSecond() function.
+
+ ***Tamper configuration ***
+ ===========================
+ [..]
+ (+) Configure the Tamper filter count using RTC_TamperFilterConfig()
+ function.
+ (+) Configure the RTC Tamper trigger Edge or Level according to the Tamper
+ filter (if equal to 0 Edge else Level) value using the RTC_TamperConfig()
+ function.
+ (+) Configure the Tamper sampling frequency using RTC_TamperSamplingFreqConfig()
+ function.
+ (+) Configure the Tamper precharge or discharge duration using
+ RTC_TamperPinsPrechargeDuration() function.
+ (+) Enable the Tamper Pull-UP using RTC_TamperPullUpDisableCmd() function.
+ (+) Enable the RTC Tamper using the RTC_TamperCmd() function.
+ (+) Enable the Time stamp on Tamper detection event using
+ RTC_TSOnTamperDetecCmd() function.
+
+ ***Backup Data Registers configuration ***
+ ==========================================
+ [..]
+ (+) To write to the RTC Backup Data registers, use the RTC_WriteBackupRegister()
+ function.
+ (+) To read the RTC Backup Data registers, use the RTC_ReadBackupRegister()
+ function.
+
+ ##### RTC and low power modes #####
+ ===============================================================================
+ [..] The MCU can be woken up from a low power mode by an RTC alternate
+ function.
+ [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
+ RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
+ These RTC alternate functions can wake up the system from the Stop
+ and Standby lowpower modes.
+ The system can also wake up from low power modes without depending
+ on an external interrupt (Auto-wakeup mode), by using the RTC alarm
+ or the RTC wakeup events.
+ [..] The RTC provides a programmable time base for waking up from the
+ Stop or Standby mode at regular intervals.
+ Wakeup from STOP and Standby modes is possible only when the RTC
+ clock source is LSE or LSI.
+
+ ##### Selection of RTC_AF1 alternate functions #####
+ ===============================================================================
+ [..] The RTC_AF1 pin (PC13) can be used for the following purposes:
+ (+) Wakeup pin 2 (WKUP2) using the PWR_WakeUpPinCmd() function.
+ (+) AFO_ALARM output.
+ (+) AFO_CALIB output.
+ (+) AFI_TAMPER.
+ (+) AFI_TIMESTAMP.

+ ##### Initialization and Configuration functions #####
+ ===============================================================================
+ [..] This section provide functions allowing to initialize and configure the
+ RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
+ RTC registers Write protection, enter and exit the RTC initialization mode,
+ RTC registers synchronization check and reference clock detection enable.
+ (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
+ It is split into 2 programmable prescalers to minimize power consumption.
+ (++) A 7-bit asynchronous prescaler and A 13-bit synchronous prescaler.
+ (++) When both prescalers are used, it is recommended to configure the
+ asynchronous prescaler to a high value to minimize consumption.
+ (#) All RTC registers are Write protected. Writing to the RTC registers
+ is enabled by writing a key into the Write Protection register, RTC_WPR.
+ (#) To Configure the RTC Calendar, user application should enter
+ initialization mode. In this mode, the calendar counter is stopped
+ and its value can be updated. When the initialization sequence is
+ complete, the calendar restarts counting after 4 RTCCLK cycles.
+ (#) To read the calendar through the shadow registers after Calendar
+ initialization, calendar update or after wakeup from low power modes
+ the software must first clear the RSF flag. The software must then
+ wait until it is set again before reading the calendar, which means
+ that the calendar registers have been correctly copied into the
+ RTC_TR and RTC_DR shadow registers.The RTC_WaitForSynchro() function
+ implements the above software sequence (RSF clear and RSF check).

+ * @date 20-April-2015
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the SDIO peripheral:
+ * + Initialization
+ * + Interrupts and flags management
+ *
+ * @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) The SDIO clock (SDIOCLK = 48 MHz) is coming from a specific output of PLL
+ (PLLVCO) througth a fixed divider by 2.
+ Before to start working with SDIO peripheral make sure that the PLLVCO is
+ well configured to 96MHz.
+ The SDIO peripheral uses two clock signals:
+ (++) SDIO adapter clock (SDIOCLK = 48 MHz).
+ (++) APB2 bus clock (PCLK2).
+ PCLK2 and SDIO_CK clock frequencies must respect the following
+ condition: Frequenc(PCLK2) >= (3 / 8 x Frequency(SDIO_CK)).
+ (#) Enable peripheral clock using
+ RCC_APB2PeriphClockCmd(RCC_APB2Periph_SDIO, ENABLE).
+ (#) According to the SDIO mode, enable the GPIO clocks using
+ RCC_AHBPeriphClockCmd() function.
+ The I/O can be one of the following configurations:
+ (++) 1-bit data length: SDIO_CMD, SDIO_CK and D0.
+ (++) 4-bit data length: SDIO_CMD, SDIO_CK and D[3:0].
+ (++) 8-bit data length: SDIO_CMD, SDIO_CK and D[7:0].
+
+ (#) Peripheral's alternate function:
+ (++) Connect the pin to the desired peripherals' Alternate
+ Function (AF) using GPIO_PinAFConfig() function.
+ (++) Configure the desired pin in alternate function by:
+ GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF.
+ (++) Select the type, pull-up/pull-down and output speed via
+ GPIO_PuPd, GPIO_OType and GPIO_Speed members.
+ (++) Call GPIO_Init() function.
+
+ (#) Program the Clock Edge, Clock Bypass, Clock Power Save, Bus Wide,
+ hardware, flow control and the Clock Divider using the SDIO_Init()
+ function.
+ (#) Enable the Power ON State using the SDIO_SetPowerState(SDIO_PowerState_ON)
+ function.
+ (#) Enable the clock using the SDIO_ClockCmd() function.
+ (#) Enable the NVIC and the corresponding interrupt using the function
+ SDIO_ITConfig() if you need to use interrupt mode.
+ (#) When using the DMA mode
+ (++) Configure the DMA using DMA_Init() function.
+ (++) Active the needed channel Request using SDIO_DMACmd() function.
+ (#) Enable the DMA using the DMA_Cmd() function, when using DMA mode.
+ (#) To control the CPSM (Command Path State Machine) and send commands to the
+ card use the SDIO_SendCommand(), SDIO_GetCommandResponse() and
+ SDIO_GetResponse() functions. First, user has to fill the command
+ structure (pointer to SDIO_CmdInitTypeDef) according to the selected
+ command to be sent. The parameters that should be filled are:
+ (++) Command Argument.
+ (++) Command Index.
+ (++) Command Response type.
+ (++) Command Wait.
+ (++) CPSM Status (Enable or Disable).
+ To check if the command is well received, read the SDIO_CMDRESP register
+ using the SDIO_GetCommandResponse(). The SDIO responses registers
+ (SDIO_RESP1 to SDIO_RESP2), use the SDIO_GetResponse() function.
+ (#) To control the DPSM (Data Path State Machine) and send/receive
+ data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(),
+ SDIO_ReadData(), SDIO_WriteData() and SDIO_GetFIFOCount() functions.
+
+ *** Read Operations ***
+ -----------------------
+ [..]
+ (#) First, user has to fill the data structure (pointer to
+ SDIO_DataInitTypeDef) according to the selected data type to be received.
+ The parameters that should be filled are:
+ (++) Data TimeOut.
+ (++) Data Length.
+ (++) Data Block size.
+ (++) Data Transfer direction: should be from card (To SDIO).
+ (++) Data Transfer mode.
+ (++) DPSM Status (Enable or Disable).
+ (#) Configure the SDIO resources to receive the data from the card
+ according to selected transfer mode (Refer to Step 8, 9 and 10).
+ (#) Send the selected Read command (refer to step 11).
+ (#) Use the SDIO flags/interrupts to check the transfer status.
+
+ *** Write Operations ***
+ ------------------------
+ [..]
+ (#) First, user has to fill the data structure (pointer to

+ * functionalities of the Serial peripheral interface (SPI):
+ * + Initialization and Configuration
+ * + Data transfers functions
+ * + Hardware CRC Calculation
+ * + DMA transfers management
+ * + Interrupts and flags management
+ *

+ Medium-density Plus and High-density devices.
+
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ (#) Enable peripheral clock using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE)
+ function for SPI1 or using RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI2, ENABLE)
+ function for SPI2 or using RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI3, ENABLE)
+ for SPI3.
+
+ (#) Enable SCK, MOSI, MISO and NSS GPIO clocks using
+ RCC_AHBPeriphClockCmd() function.
+
+ (#) Peripherals alternate function:
+ (++) Connect the pin to the desired peripherals' Alternate
+ Function (AF) using GPIO_PinAFConfig() function.
+ (++) Configure the desired pin in alternate function by:
+ GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF.
+ (++) Select the type, pull-up/pull-down and output speed via
+ GPIO_PuPd, GPIO_OType and GPIO_Speed members.
+ (++) Call GPIO_Init() function.
+
+ (#) Program the Polarity, Phase, First Data, Baud Rate Prescaler, Slave
+ Management, Peripheral Mode and CRC Polynomial values using the SPI_Init()
+ function.In I2S mode, program the Mode, Standard, Data Format, MCLK
+ Output, Audio frequency and Polarity using I2S_Init() function.
+
+ (#) Enable the NVIC and the corresponding interrupt using the function
+ SPI_ITConfig() if you need to use interrupt mode.
+
+ (#) When using the DMA mode
+ (++) Configure the DMA using DMA_Init() function.
+ (++) Active the needed channel Request using SPI_I2S_DMACmd() function.
+
+ (#) Enable the SPI using the SPI_Cmd() function or enable the I2S using
+ I2S_Cmd().
+
+ (#) Enable the DMA using the DMA_Cmd() function when using DMA mode.
+
+ (#) Optionally, you can enable/configure the following parameters without
+ re-initialization (i.e there is no need to call again SPI_Init() function):
+ (++) When bidirectional mode (SPI_Direction_1Line_Rx or SPI_Direction_1Line_Tx)
+ is programmed as Data direction parameter using the SPI_Init()
+ function it can be possible to switch between SPI_Direction_Tx
+ or SPI_Direction_Rx using the SPI_BiDirectionalLineConfig() function.
+ (++) When SPI_NSS_Soft is selected as Slave Select Management parameter
+ using the SPI_Init() function it can be possible to manage the
+ NSS internal signal using the SPI_NSSInternalSoftwareConfig() function.
+ (++) Reconfigure the data size using the SPI_DataSizeConfig() function.
+ (++) Enable or disable the SS output using the SPI_SSOutputCmd() function.
+
+ (#) To use the CRC Hardware calculation feature refer to the Peripheral
+ CRC hardware Calculation subsection.

+ ##### Hardware CRC Calculation functions #####
+ ===============================================================================
+ [..] This section provides a set of functions allowing to manage the SPI CRC
+ hardware calculation SPI communication using CRC is possible through
+ the following procedure:
+ (#) Program the Data direction, Polarity, Phase, First Data, Baud Rate
+ Prescaler, Slave Management, Peripheral Mode and CRC Polynomial
+ values using the SPI_Init() function.
+ (#) Enable the CRC calculation using the SPI_CalculateCRC() function.
+ (#) Enable the SPI using the SPI_Cmd() function.
+ (#) Before writing the last data to the TX buffer, set the CRCNext bit
+ using the SPI_TransmitCRC() function to indicate that after
+ transmission of the last data, the CRC should be transmitted.
+ (#) After transmitting the last data, the SPI transmits the CRC.
+ The SPI_CR1_CRCNEXT bit is reset. The CRC is also received and
+ compared against the SPI_RXCRCR value.
+ If the value does not match, the SPI_FLAG_CRCERR flag is set and an
+ interrupt can be generated when the SPI_I2S_IT_ERR interrupt is enabled.
+ -@-
+ (+@) It is advised to don't read the calculate CRC values during the communication.
+ (+@) When the SPI is in slave mode, be careful to enable CRC calculation only
+ when the clock is stable, that is, when the clock is in the steady state.
+ If not, a wrong CRC calculation may be done. In fact, the CRC is sensitive
+ to the SCK slave input clock as soon as CRCEN is set, and this, whatever
+ the value of the SPE bit.
+ (+@) With high bitrate frequencies, be careful when transmitting the CRC.
+ As the number of used CPU cycles has to be as low as possible in the CRC
+ transfer phase, it is forbidden to call software functions in the CRC
+ transmission sequence to avoid errors in the last data and CRC reception.
+ In fact, CRCNEXT bit has to be written before the end of the transmission/
+ reception of the last data.
+ (+@) For high bit rate frequencies, it is advised to use the DMA mode to avoid the
+ degradation of the SPI speed performance due to CPU accesses impacting the
+ SPI bandwidth.
+ (+@) When the STM32L15xxx are configured as slaves and the NSS hardware mode is
+ used, the NSS pin needs to be kept low between the data phase and the CRC
+ phase.
+ (+@) When the SPI is configured in slave mode with the CRC feature enabled, CRC
+ calculation takes place even if a high level is applied on the NSS pin.
+ This may happen for example in case of a multislave environment where the
+ communication master addresses slaves alternately.
+ (+@) Between a slave deselection (high level on NSS) and a new slave selection
+ (low level on NSS), the CRC value should be cleared on both master and slave
+ sides in order to resynchronize the master and slave for their respective
+ CRC calculation.
+ -@- To clear the CRC, follow the procedure below:
+ (#@) Disable SPI using the SPI_Cmd() function
+ (#@) Disable the CRC calculation using the SPI_CalculateCRC() function.
+ (#@) Enable the CRC calculation using the SPI_CalculateCRC() function.

+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..] This driver provides functions for:
+ (#) Remapping the memory accessible in the code area using
+ SYSCFG_MemoryRemapConfig().
+ (#) Manage the EXTI lines connection to the GPIOs using
+ SYSCFG_EXTILineConfig().
+ (#) Routing of I/Os toward the input captures of timers (TIM2, TIM3 and TIM4).
+ (#) Input routing of COMP1 and COMP2.
+ (#) Routing of internal reference voltage VREFINT to PB0 and PB1.
+ (#) The RI registers can be accessed only when the comparator
+ APB interface clock is enabled.
+ To enable comparator clock use:
+ RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE).
+ Following functions uses RI registers:
+ (++) SYSCFG_RIDeInit()
+ (++) SYSCFG_RITIMSelect()

+ (++) SYSCFG_RISwitchControlModeCmd()
+ (++) SYSCFG_RIHysteresisConfig()
+ (#) The SYSCFG registers can be accessed only when the SYSCFG
+ interface APB clock is enabled.
+ To enable SYSCFG APB clock use:
+ RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
+ Following functions uses SYSCFG registers:
+ (++) SYSCFG_DeInit()
+ (++) SYSCFG_MemoryRemapConfig()
+ (++) SYSCFG_GetBootMode()
+ (++) SYSCFG_USBPuCmd()
+ (++) SYSCFG_EXTILineConfig()

+ *** TIM Driver: how to use it in Output Compare Mode ***
+ ===============================================================================
+ [..] To use the Timer in Output Compare mode, the following steps are mandatory:
+ (#) Enable TIM clock using
+ RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE) function.
+ (#) Configure the TIM pins by configuring the corresponding GPIO pins
+ (#) Configure the Time base unit as described in the first part of this
+ driver, if needed, else the Timer will run with the default
+ configuration:
+ (++) Autoreload value = 0xFFFF.
+ (++) Prescaler value = 0x0000.
+ (++) Counter mode = Up counting.
+ (++) Clock Division = TIM_CKD_DIV1.
+ (#) Fill the TIM_OCInitStruct with the desired parameters including:
+ (++) The TIM Output Compare mode: TIM_OCMode.
+ (++) TIM Output State: TIM_OutputState.
+ (++) TIM Pulse value: TIM_Pulse.
+ (++) TIM Output Compare Polarity : TIM_OCPolarity.
+ (#) Call TIM_OCxInit(TIMx, &TIM_OCInitStruct) to configure the desired
+ channel with the corresponding configuration.
+ (#) Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
+ [..]
+ (@) All other functions can be used separately to modify, if needed,
+ a specific feature of the Timer.
+ (@) In case of PWM mode, this function is mandatory:
+ TIM_OCxPreloadConfig(TIMx, TIM_OCPreload_ENABLE).
+ (@) If the corresponding interrupt or DMA request are needed, the user should:
+ (#@) Enable the NVIC (or the DMA) to use the TIM interrupts (or DMA requests).
+ (#@) Enable the corresponding interrupt (or DMA request) using the function
+ TIM_ITConfig(TIMx, TIM_IT_CCx) (or TIM_DMA_Cmd(TIMx, TIM_DMA_CCx)).

+ function.
+ (#) Configure the TIM pins by configuring the corresponding GPIO pins.
+ (#) Configure the Time base unit as described in the first part of this
+ driver, if needed, else the Timer will run with the default configuration:
+ (++) Autoreload value = 0xFFFF.
+ (++) Prescaler value = 0x0000.
+ (++) Counter mode = Up counting.
+ (++) Clock Division = TIM_CKD_DIV1.
+ (#) Fill the TIM_ICInitStruct with the desired parameters including:
+ (++) TIM Channel: TIM_Channel.
+ (++) TIM Input Capture polarity: TIM_ICPolarity.
+ (++) TIM Input Capture selection: TIM_ICSelection.
+ (++) TIM Input Capture Prescaler: TIM_ICPrescaler.
+ (++) TIM Input CApture filter value: TIM_ICFilter.
+ (#) Call TIM_ICInit(TIMx, &TIM_ICInitStruct) to configure the desired
+ channel with the corresponding configuration and to measure only
+ frequency or duty cycle of the input signal,or, Call
+ TIM_PWMIConfig(TIMx, &TIM_ICInitStruct) to configure the desired
+ channels with the corresponding configuration and to measure the
+ frequency and the duty cycle of the input signal.
+ (#) Enable the NVIC or the DMA to read the measured frequency.
+ (#) Enable the corresponding interrupt (or DMA request) to read
+ the Captured value, using the function TIM_ITConfig(TIMx, TIM_IT_CCx)
+ (or TIM_DMA_Cmd(TIMx, TIM_DMA_CCx)).
+ (#) Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
+ (#) Use TIM_GetCapturex(TIMx); to read the captured value.

+ [..]
+ This subsection provides a set of functions allowing to initialize the USART
+ in asynchronous and in synchronous modes.
+ (+) For the asynchronous mode only these parameters can be configured:
+ (+) Baud Rate.
+ (+) Word Length.
+ (+) Stop Bit.
+ (+) Parity: If the parity is enabled, then the MSB bit of the data written
+ in the data register is transmitted but is changed by the parity bit.
+ Depending on the frame length defined by the M bit (8-bits or 9-bits),
+ the possible USART frame formats are as listed in the following table:
+ [..]
+ +-------------------------------------------------------------+
+ | M bit | PCE bit | USART frame |
+ |---------------------|---------------------------------------|
+ | 0 | 0 | | SB | 8 bit data | STB | |
+ |---------|-----------|---------------------------------------|
+ | 0 | 1 | | SB | 7 bit data | PB | STB | |
+ |---------|-----------|---------------------------------------|
+ | 1 | 0 | | SB | 9 bit data | STB | |
+ |---------|-----------|---------------------------------------|
+ | 1 | 1 | | SB | 8 bit data | PB | STB | |
+ +-------------------------------------------------------------+
+ [..]
+ (+) Hardware flow control.
+ (+) Receiver/transmitter modes.
+ [..] The USART_Init() function follows the USART asynchronous configuration
+ procedure(details for the procedure are available in reference manual
+ (RM0038)).
+ (+) For the synchronous mode in addition to the asynchronous mode parameters
+ these parameters should be also configured:
+ (++) USART Clock Enabled.
+ (++) USART polarity.
+ (++) USART phase.
+ (++) USART LastBit.
+ [..] These parameters can be configured using the USART_ClockInit() function.

+ * @file stm32l1xx_wwdg.c
+ * @author MCD Application Team
+ * @version V1.3.1
+ * @date 20-April-2015
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the Window watchdog (WWDG) peripheral:
+ * + Prescaler, Refresh window and Counter configuration
+ * + WWDG activation
+ * + Interrupts and flags management
+ *
+ * @verbatim
+ *
+ ==============================================================================
+ ##### WWDG features #####
+ ==============================================================================
+ [..] Once enabled the WWDG generates a system reset on expiry of a programmed
+ time period, unless the program refreshes the counter (downcounter)
+ before to reach 0x3F value (i.e. a reset is generated when the counter
+ value rolls over from 0x40 to 0x3F).
+ [..] An MCU reset is also generated if the counter value is refreshed
+ before the counter has reached the refresh window value. This
+ implies that the counter must be refreshed in a limited window.
+
+ [..] Once enabled the WWDG cannot be disabled except by a system reset.
+
+ [..] WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
+ reset occurs.
+
+ [..] The WWDG counter input clock is derived from the APB clock divided
+ by a programmable prescaler.
+
+ [..] WWDG counter clock = PCLK1 / Prescaler.
+ [..] WWDG timeout = (WWDG counter clock) * (counter value).
+
+ [..] Min-max timeout value @32MHz (PCLK1): ~128us / ~65.6ms.
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Enable WWDG clock using RCC_APB1PeriphClockCmd(RCC_APB1Periph_WWDG, ENABLE)
+ function.
+
+ (#) Configure the WWDG prescaler using WWDG_SetPrescaler() function.
+
+ (#) Configure the WWDG refresh window using WWDG_SetWindowValue() function.
+
+ (#) Set the WWDG counter value and start it using WWDG_Enable() function.
+ When the WWDG is enabled the counter value should be configured to
+ a value greater than 0x40 to prevent generating an immediate reset.
+
+ (#) Optionally you can enable the Early wakeup interrupt which is
+ generated when the counter reach 0x40.
+ Once enabled this interrupt cannot be disabled except by a system reset.
+
+ (#) Then the application program must refresh the WWDG counter at regular
+ intervals during normal operation to prevent an MCU reset, using
+ WWDG_SetCounter() function. This operation must occur only when
+ the counter value is lower than the refresh window value,
+ programmed using WWDG_SetWindowValue().
