I use the 1100s all the time for comms work. I used the dev kit to get the proper code and programmed it in with a microchip processor and Pic Basic Pro. I cut out the development uP entirely so I can't help you there.Since this is a PBP website, I don't think you will get much help for a 'C' compiler. You might even get a little flamed, but not too badly. Why don't you go directly to the chip? You can PM me if you need further info
