> >I don't want to go to the AVR base because I have no development stuff for the series - right now the only thing I have to work with is the PIC MPLAB and the flash devices. You have my sympathies :) Still, even in the pic, it's workable. I did a command interpreter for a tokenized language in EE, plus a bunch of command routines, plus a full duplex bit-banged uart in an F84 once. I'd take a hardware uart anytime though. At least develop it that way at first, then you can go bit-banged if you must, and you're only debugging that layer. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
