for my application on dsPIC33 I need a task with 100us period time. Is it possible in FreeRTOS/OpenRTOS to define the tick time in us range?
Is the minimal tick time 1 ms (portTICKPERIODMS = 1) ?
The minimum tick period is 1 only if you make use of the portTICKRATEMS or portMSTOTICKS macros (which the demo applications do). However I think 100us is probably too fast for the dsPIC. You can have a timer other than the tick interrupt execute at that frequency, and leave the tick interrupt slower.
