> I am new to PICs, but I have a PIC16F877, I have a 9V power > supply, that The power sounds ok, but check that you battery delivers >= 8 Volt @ 10 mA. Crystal, capacitors, /MCLR pull-up? At http://www.voti.nl/wisp628 I have blink-a-led programs and circuits for most flash PICs. I recommend you start with one of these programs without modifying it. Take one step at a time!
