Hi,

working first time with RTOS and PIC and used OSA for that.
Questions:
i have a task that is aimed to work only when a flag is set, and after the flag is set then the task is run for only a scpecified time using Timers under OSA
So I have
for(;; ) {
OS_Flag_Wait_On (flag, Mask); //don't run task until mask is set
OS_Flag_Clear (flag, mask);  //clear the mask
OS_Ttimer_Run (20); // Run current task's timer for 20 ticks
         for(condition)
                {   ....../some actions
                   if (OS_Ttimer_Check()) { break;}   // If timer overflowed then break and exit this task

                 }
       }

Is this the way it should be, basically wants to run this task only when a condition is met and then run it for only a determined time?
The mask is set inside the Int routine using OS_Flag_Set(flag, mask).
The task is already created with OS_create_task...etc and I don't have any errors when compiling my concern is maybe my undestading of what OSA services are meant to do.

Gents,

Any help with that matter is highly appreciated. I am strugling with a function that I want to run only for a quantum of time. or other ways to accomplish that. I don;t want to put a load on the application by terminating that function if the allocated time is over.
