how can a vxworks task let all other lesser priority tasks run for a ...
Oct 25, 2013 · However this doesn't guarantee a 100 ms sleep, but instead a sleep of up to 100 ms or as little as 0 ms if the next clock tick is imminent. If you call taskDelay(2), then your task will sleep until the next clock tick (some time between 0 and 100 ms) plus the following clock tick (guaranteed to be 100 ms) - resulting in a total delay of between ...
