Am I supposed to hook up the header in place of the 8 pins on my IC? Hardly convenient when I have a finished board if that's the case. > > Well, have you tried powering the device thru the external 9V access on > the ICD2. Perhaps you are not > properly powering it.. What do the self-tests say? Do they pass? Yes, the 9V adapter is plugged in to the ICD and all the self-tests pass just fine. Look for a GND loop between the development PC and the product.

But doesn't work worth **** with these 12F675s. I have this ICD in my possession. Just can't figure out why it won't work. Won't recognize the chip. Just returns either a 0x000 or a 0x1FF or something like that. Can't remember and can't always duplicate it. -- Shawn Wilton (b9 Systems) http://b9Systems.com <- New web page -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
