    rtos design

    Hello Guys,

    Anybody has some documents/links to share how to design preemptive RTOS on PIC18?

    Or are there any Software that supports Preemptive RTOS (similar to Salvo but this case a preemptive RTOS instead of cooperative).

    One high priority task of my applcation (the highest priority task on my applciaiton if running anyway) is to be periodically serviced every 2000 instruction cycles (via a TIMER Interrupt) and the task itself can be serviced in less than 100 instruction cycles. So I will be forced to use preemtive RTOS in teh design since the applcation does a lot of tasks aside from this major high priority task

    Thanks,

    neo
