Can any one give me some idea how to implement the code for RTOS with CCS ( in biult functions of RTOS). I went through their manual and examples but still confused...I need to drive 2 stepper motors, scan 6 sensors(IR) give output in the LDC(16x2).

  What the algorithm must be ... I need to detect objects in the front of the bot. How the RTOS functions needs to be called ? Thanks in advance from a newbie, hope all the experienced guy gives me some tips.

yes I have gone through the manual .. and the examples as well, but a full working project would have been more helpful, if any one of you have done some work with rtos, please email/pm [tirthankar.tirtha[at]gmail] me, thanks for your reply.

I don't recommend this rtos, you will be better with your own state machine.
I have used it with version 3.249 which is the most stable version I know and only simple code works. When you start writing real applications, the rtos start to show its weakness.

Have you tried using mplab and pumpkin rtos? I do belive they are both on the forums here somewhere. I acutally designed and wrote my own rtos but for htsoft.

The book Advanced PIC Microcontroller Projects in C has an explanation and some simple RTOS projects in CCS C, this would be a good start. I believe that it may be found within these pages.

Yeah, I would really like to see a decent RTOS. Most of them makes me stumble just by setting them up...

I have coverted a fairly large project that use 95% Rom on 18F242 to use ccs rtos.
Its working fine so far.
What I discovered is that you must be very liberal with your "rtos_yield" statements.
This is because the RTOS does not necesarily share execution time between the tasks equally. This means that if you are not careful, some tasks may actually never run, or run for an unpredictable time.
One challenge is when you process an interupt request, call subroutines or functions from within a task.
I found that I could not execute a rtos_yied from the called routine.
I ended up converting some of the functions/ subroutines to tasks.

Otherwise I am happy with the rtos perfomance( at least as of now ! )
