Strange Demo Board Problem

crgwbr

Hey Everyone,

I recently discovered that P16 and P17 (first two LEDs) on my demo board·have stopped·working·. · I was just wandering if anyone else has had this happen?··I just thought it was strange for this to happen, after all, the circuits are hardwired into the board (you·can't short them).

Have you scoped the pins on the Prop chip itself? I've not had that happen, but for instance my demo board doesn't have that
green power LED that most of them seem to. I'd run a blinker program, slap a scope on the pins and see if you get any
wiggles at all.

I am running a rev. F demo board. Nothing is plugged into the VGA connecter, so I don't think that it could be that. Later today, if I have time, I going to plug a scope into it. I have a feeling that it's just the resistors they go through. I'll post what's going on after I figure it out.

Have you any prog flashed to the eeprom? or did you write a simple prog just to check these pins and then F11.Was wondering because I was getting odd results on outputs and realised it was an intercog conflict...
