thread safe sleep() #39

Closed Sylensky closed 1 year ago

Sylensky commented 1 year ago

Hi,

Is it possible to add a popular sleep(ms) function back to the scheduler? I am looking for a similiar approach to a vTaskDelay(ms) from FreeRTOS for example.

So far there is just a yield() which context-switches to the next task immediately.

@Sylensky Thanks for the question. Actually the Arduino core function delay(ms) uses yield() and thus gives the coroutine/thread version of sleep().

Oh thanks, this just pointed me into the direction of a bug in my code.
