Hi, thanks for the help.
I want to know, can we set periodicity for task? like task1 will have 1 ms periodicity, task2 will have 100 ms of periodicity.
because delay function will not give the exacttime when we task is starting to run and when this come to run.

Did you look at vTaskDelayUntil()? It is designed for just this sort of thing.
