Hi all -
This forum has already been tons of help, but now I have a question I can't find the answer to. I'm trying to build a minimum parts IR transceiver using a 12F683. I'd like to encode the IR beam at either 30 or 40 kHz (selectable) to minimize ambient light and allow two units to operate in the same area without them getting confused. I've got an darlington pair to give me adequate current and am using encoded receivers, I just don't know if it's possible to code the switch routine in PBP or if I need to do it in assembly. It seems that the docs are telling my the freq is too high for HPWM. I'd like the IR signal to run constantly.

Peace - Fiz
