Hands-On RTOS with Microcontrollers

Timers

Timers are equivalent, with static and dynamic allocation both being defined by the same osTimerNew function: 

CMSIS-RTOS name	FreeRTOS functions called	Notes
osTimerDelete	xTimerDelete	If Heap1 is used, this function returns osError. It also frees up TimerCallback_t* used by the timer to be deleted.
osTimerGetName	pcTimerGetName
osTimerIsRunning	xTimerIsTimerActive
osTimerNew	xTimerCreateStatic, xTimerCreate	Automatic allocation for TimerCallback_t.
osTimerStart	xTimerChangePeriod
osTimerStop	xTimerStop

 

Timers are very similar between the two APIs, but beware of attempting to use osTimerDelete with Heap1.
