Thanks to everyone for all their help so far.I was stupid enough to stay up all last night working on this project, and now I am so fried I can barley think!


I threw together a quick circuit & program, but it does not appear to be sending usable IR. At this point I could be missing something really basic and think I need to change gears for a few hours.

dhouston's sample code appears to be for an oscillator. How would I reduce this down to the Hz needed for my carrier? Is this program specific to the PIC12F683, or can I use it on a 12F629, 12F675 or 16F88 (chips I have available now)? Would this PIC just be used to generate the carrier, or could it also generate the complete IR stream including carrier & data pulses?

Thanks - know I will be back in the morning, against my better judgment
