Seems to work fine for me. 1) Try adding a "nop" at the exact address for your injection label. Make sure that you make a LABEL for the address, because that's what you need to input into MPLAB for the injection location. 2) Make sure you're in bank 1 for PORTC (I think). 3) Don't change your Reply-To address.. it's damn annoying to have to add the PICLIST to reply to your message. --Andrew _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
