I made the move from running my project with the emulator to running with the actual part today. Seems to work fine at 5V but when I switch from power supply (5V) to battery (3.6V) the PIC doesn't seem to run. I programmed the PIC with my Picstart Plus. I ordered a Promate two weeks ago but due to the efficient purchasing group they haven't placed the order yet. I seem to recall something about needing a special programmer for other than 5V supply operation. Can someone please enlighten me. The data book didn't seem to. Thanks, - -Mark
