    i'm using microcode studio, mpasm and an epic programmer.
    What does it mean system clock disabled? Does this mean no oscillator?

    im not sure... i have tried it on both enabled and disabled. those were taken from the config settings of my programmer.

    System clock is actually OSCSEN.
    While a program is running, you can switch the clock source from the main clock source (crystal, R/C, whatever) over to the Timer1 clock source, and back again.

    GOOD TO KNOW... i learn so much from all of you on here.... i know these PICs say they are static sensitive, but how bad is it?? should i be wearing a strap every time i think about looking at it?? or do i really need to worry about it. i know with the 16f devices i have used, they say they are static sensitive, but i have never worried about it and never had any problems...

    I haven't COMPLETELY blown a PIC up with static...YET! I know how dry it gets where you're at (remember, I'm just a bit south-east of you). My 'shop' is in the basement, usually about 20% humidity in the winter, carpet on the floor, and so on and so on.
    I think, that is, THINK, the worst I've done to a PIC is blow out an output driver or two on a few PICs...and I'm not even 100% sure it was static that did it. Probably from putting them in the socket backwards, etc.
    However, I've heard that the 18F's are quite a bit more static sensitive than the 16F's were, probably due to the smaller gate size on the die...not sure...don't care. As long as I don't smoke anymore, I'm all good...

    ok, i was just kind of curious... i get them from Digi-key and they come in a vacuum sealed static bag with one of those little dessicant bags in it and a humidity tester... the 16f ones, come in a little static bag thats just folded over on its self so it doesnt fall out!!

    i de-soldered the pic from the board, everything looks good under there... no solder bridges or shorts of any kind.. everything looks good... i ordered another PIC so it should be here on monday and i will try that...

    i wish there was a pin compatible 16f PIC that i could throw in there and see if i could get it to work... then i would know the board is ok...
