i have actually made d.4 an I/O connection on my board.. there is three pins, ground, + and signal (just like a servo). so i had an LED hooked to it, but since then, i have just hooked up my multimeter, and its not showing any voltage across signal to ground when i put it high. i do get 5V across the + and ground. and i can write code to the PIC, and i can read the same code back off the PIC.. its a double stacked board, and i soldered the headers into both boards, so i may need to try to get them apart to look inside where the PIC is..
