Is there an API call (or equivalent) to tell if the scheduler is running?

I have some functions that use FreeRTOS calls if the scheduler is running, and other calls if not.

While I certainly could set a global when I call vTaskStartScheduler, is there a reliable way to ask FreeRTOS if its scheduler has been started?

There is xTaskGetSchedulerState available if INCLUDE_xTaskGetSchedulerState is enabled.

Perfect – that’s exactly what’s needed. In particular:

static void bsp_delay_ms(bsp_duration_t ms) {
    if (xTaskGetSchedulerState() == taskSCHEDULER_NOT_STARTED) {
      delay_ms(ms);
    } else {
      vTaskDelay(pdMS_TO_TICKS(ms));
    }
}
