Hi all (again), In the documentation, it is stated that the default (1000hz) tick is higher than normally would be required. What I notice is, that when i increase the tick count to 1050hz I never get a tick count. This happens only when there is a task available. When I just start the scheduler, i can get as high as 10.000 without any problem. I get the tick count by using a trace macro on the PIC32. What is this about? The task that is running is the only task and has nothing in it (except a continuous loop). But my main question is, what is the best (highest) tick count without (crashing) sooner or later the tick count?

Sorry, had to add this text too. And when I select a tick rate off 100, the task will run continuously. (Also measured using trace functions) This is the tasks only function:     while(1){         vTaskDelay(5 / portTICK_RATE_MS );             }

portTICK_RATE_MS will be less than 0 if configTICK_RATE_HZ is greater than 1000. As its an integer it will probably be a divide by  zero.

I just found out so :) Thank you very much!

If you want, use the following macro for a generic greater than 1000 ticks converter: #define rtos_convert_to_ms(A)  (((A * 1000)/(1000000 / configTICK_RATE_HZ)))
