How to obtain delay in the order of 50us on TMDX570LC43HDK with FreeRtos
Hy,
I would like to obtain delay in the order of 50us on a FreeRTOS having a tick of 1ms (1000Hz) on TMDX570LC43HDK, I’m almost sure that this is a non sense,
so the solution could be a tick for example of 10us, is it a realistic solution to this kind of problem?
Thanks
Antonio

No, leave tick at 1 to 100ms and use a timer on interrupts for your
delay. If it happen infrequently, you might be able to use a delay loop.
All depends on your system design.
Haveing a tick at 50 or 10us would use a lot of CPU resources in the
FreeRTOS scheduler doing nothing very useful.

Antonio, in my opinion: when you need a delay of more that a ms, you could have the task sleep by calling e.g.
vTaskDelay()
.
When you want to wait for 50 uS, you can go either of two ways:
- Set-up a timer-counter that you can poll and wait 50 uS in a loop.
- Write a loop that has a predictable speed of execution.
