How can i make sure that my PIC is functional? I use PIC16F88 and PicKit2. I connected PIC with my robot and programmed couple of times. Suddenly all programming fails and I get error "Unsupported Part (ID=3FE0)". I googled it and everyone said it is a power error. I took PIC away from robot and used breadboard to connect it with PicKit. No other components were used. It still showed error when trying to program. When i clicked "Check communication" PicKit found the PIC but if i try to program it doesn't.
Finally I took other PIC (PIC16F818) and used that for robot. And same thing happened. Couple of times good programming and then "Unsupported Part (ID=3FE0)". On robot and on breadboard.
I think maybe h-bridge (L298N) tried to get much current from logic input pins or something like that. Although it is very weird because it worked perfectly yesterday.
