    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    I'm going to have to agree with you I think.I suppose I have one good PIC and one bad, but I would think I would have difficulty reading from the ports of aa bad one, or at the very least the programmer would fail to recognize it.Maybe I'm asking for too much.

    Bruce, I haven't tried your code yet.I'm afraid your suggestion got buried in the conversation.I think I'll give it a try and post the results later if I have any success.

    Thanks for everyone for helping me figure this out.I'm sure I'll have many more questions as I go

    Lightbulb Idea

    Hi,

    I'd suggest you to try to place 4.7k and 22 pf as the external RC Clock components ... and give a try like that ...

    no risk !

    Will tell if CONFIG Word is transmitted by the programmer ...

    Just one step further.

    Do you mean to use a 4.7 k resistor instead of the crystal and set the oscillator at RC?
