+/* ----------------------------------------------------------------------
+ * $Date: 5. February 2013
+ * $Revision: V1.02
+ *
+ * Project: CMSIS-RTOS API
+ * Title: cmsis_os.c
+ *
+ * Version 0.02
+ * Initial Proposal Phase
+ * Version 0.03
+ * osKernelStart added, optional feature: main started as thread
+ * osSemaphores have standard behavior
+ * osTimerCreate does not start the timer, added osTimerStart
+ * osThreadPass is renamed to osThreadYield
+ * Version 1.01
+ * Support for C++ interface
+ * - const attribute removed from the osXxxxDef_t typedef's
+ * - const attribute added to the osXxxxDef macros
+ * Added: osTimerDelete, osMutexDelete, osSemaphoreDelete
+ * Added: osKernelInitialize
+ * Version 1.02
+ * Control functions for short timeouts in microsecond resolution:
+ * Added: osKernelSysTick, osKernelSysTickFrequency, osKernelSysTickMicroSec
+ * Removed: osSignalGet
+ *
