/* ----------------------------------------------------------------------
* $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
*
