+ * @brief SMARTCARD HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the SMARTCARD peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ * + Peripheral State and Error functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The SMARTCARD HAL driver can be used as follows:
+
+ (#) Declare a SMARTCARD_HandleTypeDef handle structure.
+ (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
+ (##) Enable the interface clock of the USARTx associated to the SMARTCARD.
+ (##) SMARTCARD pins configuration:
+ (+++) Enable the clock for the SMARTCARD GPIOs.
+ (+++) Configure SMARTCARD pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
+ and HAL_SMARTCARD_Receive_IT() APIs):
+ (+++) Configure the USARTx interrupt priority.
+ (+++) Enable the NVIC USART IRQ handle.
+ (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
+ and HAL_SMARTCARD_Receive_DMA() APIs):
+ (+++) Declare a DMA handle structure for the Tx/Rx channel.
+ (+++) Enable the DMAx interface clock.
+ (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+ (+++) Configure the DMA Tx/Rx channel.
+ (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
+ (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
+ (used for last byte sending completion detection in DMA non circular mode)
+
+ (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware
+ flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure.
+
+ (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
+ (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customized HAL_SMARTCARD_MspInit() API.
+ [..]
+ (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
+
+ [..]
+ Three operation modes are available within this driver :
+
+ *** Polling mode IO operation ***
+ =================================
+ [..]
+ (+) Send an amount of data in blocking mode using HAL_SMARTCARD_Transmit()
+ (+) Receive an amount of data in blocking mode using HAL_SMARTCARD_Receive()
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Send an amount of data in non blocking mode using HAL_SMARTCARD_Transmit_IT()
+ (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
+ (+) Receive an amount of data in non blocking mode using HAL_SMARTCARD_Receive_IT()
+ (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
+ (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback
+
+ *** DMA mode IO operation ***
+ ==============================
+ [..]
+ (+) Send an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Transmit_DMA()
+ (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
+ (+) Receive an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Receive_DMA()
+ (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
+ (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback
+
+ *** SMARTCARD HAL driver macros list ***
+ ========================================
+ [..]
+ Below the list of most used macros in SMARTCARD HAL driver.
+
+ (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral
+ (+) __HAL_SMARTCARD_DISABLE: Disable the SMARTCARD peripheral
+ (+) __HAL_SMARTCARD_GET_FLAG : Check whether the specified SMARTCARD flag is set or not
+ (+) __HAL_SMARTCARD_CLEAR_FLAG : Clear the specified SMARTCARD pending flag
+ (+) __HAL_SMARTCARD_ENABLE_IT: Enable the specified SMARTCARD interrupt
+ (+) __HAL_SMARTCARD_DISABLE_IT: Disable the specified SMARTCARD interrupt
+
+ [..]
+ (@) You can refer to the SMARTCARD HAL driver header file for more useful macros
+
+ ##### Callback registration #####
+ ==================================
+
+ [..]
+ The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+
+ [..]
+ Use Function @ref HAL_SMARTCARD_RegisterCallback() to register a user callback.
+ Function @ref HAL_SMARTCARD_RegisterCallback() allows to register following callbacks:
+ (+) TxCpltCallback : Tx Complete Callback.
+ (+) RxCpltCallback : Rx Complete Callback.
+ (+) ErrorCallback : Error Callback.
+ (+) AbortCpltCallback : Abort Complete Callback.
+ (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
+ (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
+ (+) MspInitCallback : SMARTCARD MspInit.
+ (+) MspDeInitCallback : SMARTCARD MspDeInit.
+ This function takes as parameters the HAL peripheral handle, the Callback ID
+ and a pointer to the user callback function.
+
+ [..]
+ Use function @ref HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default
+ weak (surcharged) function.
+ @ref HAL_SMARTCARD_UnRegisterCallback() takes as parameters the HAL peripheral handle,
+ and the Callback ID.
+ This function allows to reset following callbacks:
+ (+) TxCpltCallback : Tx Complete Callback.
+ (+) RxCpltCallback : Rx Complete Callback.
+ (+) ErrorCallback : Error Callback.
+ (+) AbortCpltCallback : Abort Complete Callback.
+ (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
+ (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
+ (+) MspInitCallback : SMARTCARD MspInit.
+ (+) MspDeInitCallback : SMARTCARD MspDeInit.
+
+ [..]
+ By default, after the @ref HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET
+ all callbacks are set to the corresponding weak (surcharged) functions:
+ examples @ref HAL_SMARTCARD_TxCpltCallback(), @ref HAL_SMARTCARD_RxCpltCallback().
+ Exception done for MspInit and MspDeInit functions that are respectively
+ reset to the legacy weak (surcharged) functions in the @ref HAL_SMARTCARD_Init()
+ and @ref HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand).
+ If not, MspInit or MspDeInit are not null, the @ref HAL_SMARTCARD_Init() and @ref HAL_SMARTCARD_DeInit()
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
+
+ [..]
+ Callbacks can be registered/unregistered in HAL_SMARTCARD_STATE_READY state only.
+ Exception done MspInit/MspDeInit that can be registered/unregistered
+ in HAL_SMARTCARD_STATE_READY or HAL_SMARTCARD_STATE_RESET state, thus registered (user)
+ MspInit/DeInit callbacks can be used during the Init/DeInit.
+ In that case first register the MspInit/MspDeInit user callbacks
+ using @ref HAL_SMARTCARD_RegisterCallback() before calling @ref HAL_SMARTCARD_DeInit()
+ or @ref HAL_SMARTCARD_Init() function.
+
+ [..]
+ When The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS is set to 0 or
+ not defined, the callback registration feature is not available
+ and weak (surcharged) callbacks are used.

+ ##### Initialization and Configuration functions #####
+ ==============================================================================
+ [..]
+ This subsection provides a set of functions allowing to initialize the USART
+ in Smartcard mode.
+ [..]
+ The Smartcard interface is designed to support asynchronous protocol Smartcards as
+ defined in the ISO 7816-3 standard.
+ [..]
+ The USART can provide a clock to the smartcard through the SCLK output.
+ In smartcard mode, SCLK is not associated to the communication but is simply derived
+ from the internal peripheral input clock through a 5-bit prescaler.
+ [..]
+ (+) For the Smartcard mode only these parameters can be configured:
+ (++) Baud Rate
+ (++) Word Length => Should be 9 bits (8 bits + parity)
+ (++) Stop Bit
+ (++) Parity: => Should be enabled
+ (++) USART polarity
+ (++) USART phase
+ (++) USART LastBit
+ (++) Receiver/transmitter modes
+ (++) Prescaler
+ (++) GuardTime
+ (++) NACKState: The Smartcard NACK state
+
+ (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
+ (++) Word Length = 9 Bits
+ (++) 1.5 Stop Bit
+ (++) Even parity
+ (++) BaudRate = 12096 baud
+ (++) Tx and Rx enabled
+ [..]
+ Please refer to the ISO 7816-3 specification for more details.
+
+ [..]
+ (@) It is also possible to choose 0.5 stop bit for receiving but it is recommended
+ to use 1.5 stop bits for both transmitting and receiving to avoid switching
+ between the two configurations.
+ [..]
+ The HAL_SMARTCARD_Init() function follows the USART SmartCard configuration
+ procedures (details for the procedures are available in reference manuals
+ (RM0008 for STM32F10Xxx MCUs and RM0041 for STM32F100xx MCUs)).
+
+@endverbatim
+
+ The SMARTCARD frame format is given in the following table:
+ +-------------------------------------------------------------+
+ | M bit | PCE bit | SMARTCARD frame |
+ |---------------------|---------------------------------------|
+ | 1 | 1 | | SB | 8 bit data | PB | STB | |
+ +-------------------------------------------------------------+

+ ===============================================================================
+ ##### IO operation functions #####
+ ===============================================================================
+ [..]
+ This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
+
+ [..]
+ (#) Smartcard is a single wire half duplex communication protocol.
+ The Smartcard interface is designed to support asynchronous protocol Smartcards as
+ defined in the ISO 7816-3 standard.
+ (#) The USART should be configured as:
+ (++) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
+ (++) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.
+
+ (#) There are two modes of transfer:
+ (++) Blocking mode: The communication is performed in polling mode.
+ The HAL status of all data processing is returned by the same function
+ after finishing transfer.
+ (++) Non Blocking mode: The communication is performed using Interrupts
+ or DMA, These APIs return the HAL status.
+ The end of the data processing will be indicated through the
+ dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
+ using DMA mode.
+ The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
+ will be executed respectively at the end of the Transmit or Receive process
+ The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication error is detected
+
+ (#) Blocking mode APIs are :
+ (++) HAL_SMARTCARD_Transmit()
+ (++) HAL_SMARTCARD_Receive()
+
+ (#) Non Blocking mode APIs with Interrupt are :
+ (++) HAL_SMARTCARD_Transmit_IT()
+ (++) HAL_SMARTCARD_Receive_IT()
+ (++) HAL_SMARTCARD_IRQHandler()
+
+ (#) Non Blocking mode functions with DMA are :
+ (++) HAL_SMARTCARD_Transmit_DMA()
+ (++) HAL_SMARTCARD_Receive_DMA()
+
+ (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
+ (++) HAL_SMARTCARD_TxCpltCallback()
+ (++) HAL_SMARTCARD_RxCpltCallback()
+ (++) HAL_SMARTCARD_ErrorCallback()
+
+ (#) Non-Blocking mode transfers could be aborted using Abort API's :
+ (+) HAL_SMARTCARD_Abort()
+ (+) HAL_SMARTCARD_AbortTransmit()
+ (+) HAL_SMARTCARD_AbortReceive()
+ (+) HAL_SMARTCARD_Abort_IT()
+ (+) HAL_SMARTCARD_AbortTransmit_IT()
+ (+) HAL_SMARTCARD_AbortReceive_IT()
+
+ (#) For Abort services based on interrupts (HAL_SMARTCARD_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
+ (+) HAL_SMARTCARD_AbortCpltCallback()
+ (+) HAL_SMARTCARD_AbortTransmitCpltCallback()
+ (+) HAL_SMARTCARD_AbortReceiveCpltCallback()
+
+ (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
+ Errors are handled as follows :
+ (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
+ to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
+ Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
+ and HAL_SMARTCARD_ErrorCallback() user callback is executed. Transfer is kept ongoing on SMARTCARD side.
+ If user wants to abort it, Abort services should be called by user.
+ (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
+ This concerns Frame Error in Interrupt mode tranmission, Overrun Error in Interrupt mode reception and all errors in DMA mode.
+ Error code is set to allow user to identify error type, and HAL_SMARTCARD_ErrorCallback() user callback is executed.
