WebSep 10, 2024 · FreeRTOS keeps track of the elapsed time in the system by counting ticks. The tick count increases inside a periodic interrupt routine generated by one of the timers available in the host MCU. When FreeRTOS is running the Idle task hook, the microcontroller can be placed into a low power mode. WebFreeRTOS Interrupt Management. Interrupts are events that the OS scheduler can not understand. This event is made available to the scheduler by a semaphore (like a queue of length 1). There are external interrupts by attachInterrupt and alarm interrupts by RTC library as interrupt processing in GR-ROSE SDK.
