Can I use an idle hook function in FreeRTOS to perform low-priority tasks?

@Middleware & OS Hello, can I use an idle hook function in FreeRTOS to perform low-priority tasks? My idle hook isn't being executed. Here's my configuration:

      void vApplicationIdleHook(void) {
          // Perform low-priority task
      }

      void vApplicationIdleHook(void) {
          // Perform low-priority task
      }

What should I check?

Solution:

@Boss lady If your idle hook isn't being executed, check that the idle hook is enabled in your FreeRTOSConfig.h file by setting configUSE_IDLE_HOOK to 1.

#define configUSE_IDLE_HOOK 1

#define configUSE_IDLE_HOOK 1

, check that your idle hook function is correctly implemented and matches the expected function signature....

void vApplicationIdleHook(void) {
    // Perform low-priority task
}

void vApplicationIdleHook(void) {
    // Perform low-priority task
}

, make sure that there are periods when no other tasks are ready to run so the idle task can execute.
