vTaskDelay() does not work

Kernel

Hello there,
I want to create a semaphore, but the vTaskDelay() does not work, I am using the Psoc 6 and my code is below:

Can you please be slightly more specific ? Since vTaskDelay is unrelated to semaphores it’s a bit confusing…

  1. What’s the expected behaviour ?
  2. What’s the actual behaviour ?
    (What does it mean vTaskDelay does not work ? Is your program crashing ? Are the delays longer/shorter than expected ?)
  3. What did you already try to solve the problem ?

And is it intended that SINAL_PEDESTRE_1_TASK(void *arg) is running without any delay ? I guess it’s way too fast to see any LED blinking :wink:

Did you set configUSE_PREEMPTION and configUSE_TIME_SLICING to 1 in your FreeRTOSConfig.h ?

BTW For better readabilty better enclose posted code blocks by 3 backticks ``` or alternatively by starting with ~~~c and ending with ~~~ (for C-code).

Relax. I did it. I solved my problem. Thanks!

That’s good :+1:
And I am relaxed :sunglasses:

Pleased you solved the problem. Its always good in these cases if you can also post what the resolution was - that can be helpful to others with a similar issue in the future.

Hello, I solved my problem. I clicked in “FreeRTOSConfig.h” and changed the “#define configUSE_TIME_SLICING 0” for “#define configUSE_TIME_SLICING 1” and work perfectly!
