SYS/BIOS periodic tasks

Hello All,

I have a task that I created using Task_Create

Task_Params taskParams;

Task_Params_init(&taskParams);

taskParams.stackSize = 0x4000;

Task_create((Task_FuncPtr)Task, &taskParams, NULL);

I like to run this task every 125us. How can I achieve that ? Should I be using Clock_Create(but I like to have to task thread blockable)?

Thanks

The clock module is bound to system tick increments, which by default is set to 1000us per tick.

A timer in periodic mode can be run at a higher resolution. Whenever the timer's function is executed, you can to post a semaphore or some other primitive to unblock your task.

Thanks Tom for your help.

I understand the concept now, make task thread wait till clock function posts on the semaphore.
