best free RTOS for dsPIC

[NiHaoMike]

What free RTOS would you recommend for use on dsPIC? I looked at Q-Kernel but there are basically no examples of how to use it. Performance isn't all that critical so I'd prefer something that's easy to use.

Depends on what you mean by "best".

I'm just looking for something that's free (at least for personal use) and easy to get started with. It's my first time running a RTOS on a microcontroller.

I have used ucosII (not on your particular chip) in the past. Good documentation + support.

RTThread is fairly popular as well, as is freeRTOS.

Sometimes the compiler vendors will throw in a free RTOS so that's another possibility.

I think that unless you have a real mmu, running a true OS is more pain than it is worth. A job scheduler might be a more appropriate solution.
