31 A timer function is called when a time period expires whereby both on-shot and
32 periodic timers are possible. A timer can be started, restarted, or stopped.
34 Timers are handled in the thread osTimerThread.
35 Callback functions run under control of this thread and may use CMSIS-RTOS API calls.
