This function is called by FreeRTOS idle task.

This function is called by FreeRTOS each tick.

This function will be called by each tick interrupt if configUSE_TICK_HOOK is set to 1 in FreeRTOSConfig.h. User code can be added here, but the tick hook is called from an interrupt context, so code must not attempt to block, and only the interrupt safe FreeRTOS API functions can be used (those that end in FromISR()).
