Hi, Ive not touched 16F877A's for a while but now i need to use one again and im having more problems with it. Ive written some test code and ive tried mister_e's code from last time. My test code uses portD but ive tested ports A and B with mister_e's code too and im not picking anything up. Ive done all the usual checks (MCLR, Resonator, Capacitor etc). Ive checked the voltage with my oscilloscope and its extremely smooth. It almost looks like theres no load on it at all. The PIC is definately connected to it so im guessing its just not starting up correctly.

Im sure i got it working last time but i dont know how and im out of ideas now. I dont have any beer this time either . Does anyone have any ideas?
