IAR PowerPac RTOS User Guide

ParameterCallbackTimeoutpDataAdditional InformationIAR PowerPac RTOS keeps track of the timers by using a linked list. Once the timeout is expired, the callback routinewill be called immediately (unless the task is in a critical region or has interrupts disabled).This macro uses the functions OS_CreateTimer_Ex() and OS_StartTimer_Ex().OS_TIMERROUTINE_EX is defined in RTOS.h as follows:typedef void OS_TIMER_EX_ROUTINE(void *);Source of the macro (in RTOS.h):#define OS_CREATETIMER_EX(pTimerEx,cb,Timeout,pData) \OS_CreateTimerEx(pTimerEx,cb,Timeout,pData); \OS_StartTimerEx(pTimerEx);ExampleOS_TIMER TIMER100;OS_TASK TCB_HPvoid Timer100(void) {LED = LED ? 0 : 1; /* Toggle LED */if (pTask != NULL) {OS_SignalEvent(0x01, (OS_TASK*)pTask)}OS_RetriggerTimerEx(&TIMER100); /* Make timer periodical */}void InitTask(void) {/* Create and start Timer100 */OS_CREATETIMER_Ex(&TIMER100, Timer100, 100, (void*) &TCB_HP);}OS_CreateTimerEx()DescriptionCreates an extended software timer without starting it.PrototypeDescriptionTable 30: OS_CREATETIMER_EX() parameter listPointer to the callback routine to be called from the RTOS after expiration of the delay. Thecallback function has to be of type OS_TIMER_EX_ROUTINE which takes a void pointer asparameter and does not return any value.Initial timeout in basic IAR PowerPac RTOS time units (nominal ms):The data type OS_TIME is defined as an integer, therefore valid values are:1
