Guys, I have successfuly gotten a 16F84 up and running and made an attempt at getting a 16F877 up, but I'm stumped. The pic is programmed correctly (verified using a protoboard, I am blinking Port D.0 through D.2) I wired it up using the same "concept" as the 16F84: OSCin/OSCout (pins 13/14) to a Crystal (same crystal that I used on my 16F84, 10mhz). With 22pf caps to ground. 4.7k resitor to +5v on Pin 1 for MCLR. +5v on pins 11 and 32 with a .1uf cap to ground. 12 + 31 to ground. I then wired pin 21 (Port D.2) to a 470 ohm to a led... I don't see any voltage change on port D at all...as if either no clocks are running, or the chip is in reset... OR I don't know about something else I should have wired up... Anyone have any ideas? -- Aaron
