6 <table class="cmtable" summary="Revision History">
14 Additional functions allowed to be called from Interrupt Service Routines:
21 Additional functions allowed to be called from Interrupt Service Routines:
22 - \ref osKernelGetInfo, \ref osKernelGetState
28 Additional functions allowed to be called from Interrupt Service Routines:
29 - \ref osKernelGetTickCount, \ref osKernelGetTickFreq
31 Changed Kernel Tick type to uint32_t:
32 - updated: \ref osKernelGetTickCount, \ref osDelayUntil
38 Support for critical and uncritical sections (nesting safe):
39 - updated: \ref osKernelLock, \ref osKernelUnlock
40 - added: \ref osKernelRestoreLock
42 Updated \ref CMSIS_RTOS_ThreadFlagsMgmt "Thread Flags" and \ref CMSIS_RTOS_EventFlags "Event Flags":
43 - changed flags parameter and return type from int32_t to uint32_t
49 New API Version 2.0 available.
50 - See \ref rtos_api2 for a detailed function reference.
51 - See \ref os2Migration for details on the migration process from API Version 1.
55 <td>V1.02 - only documentation changes</td>
57 Added: Overview of the \ref rtosValidation "CMSIS-RTOS Validation" Software Pack.\n
58 Clarified: Behavior of \ref CMSIS_RTOS_TimeOutValue.
63 <td>Added: New control functions for short timeouts in microsecond resolution \b osKernelSysTick,
64 \b osKernelSysTickFrequency, \b osKernelSysTickMicroSec.\n
70 <td>Added capabilities for C++, kernel initialization and object deletion.\n
71 Prepared for C++ class interface. In this context to \em const attribute has been moved from osXxxxDef_t typedefs to
72 the osXxxxDef macros.\n
73 Added: \ref osTimerDelete, \ref osMutexDelete, \ref osSemaphoreDelete.\n
74 Added: \ref osKernelInitialize that prepares the kernel for object creation.\n
80 <td>First official Release.\n
81 Added: \ref osKernelStart; starting 'main' as a thread is now an optional feature.\n
82 Semaphores have now the standard behavior.\n
83 \b osTimerCreate does no longer start the timer. Added: \ref osTimerStart (replaces osTimerRestart).\n
84 Changed: osThreadPass is renamed to \ref osThreadYield.
89 <td>Preview Release.</td>
