Pic not running anything

[GatorGnet]

Is it possible for a pic to be fried from over voltage and not run its code but still be able to be programmed and read on a programmer?

Just as a double check, this is the ASM that picbasic Pro made. Maybe something is wrong with it.

Is it possible for a pic to be fried from over voltage and not run its code but still be able to be programmed and read on a programmer?

No, it's far more likely you've made a mistake in the code, or in the construction - in your other thread you were certainly not connecting things properly.

I added the caps to the power and switched to proper resistors but I am still not getting anything.

I'm starting to thing it is a programming issue. As of today, I noticed that the pic is not programming right. I have tried a couple of different program software but I usually have good luck with yours Nigel.

It reads the pic and shows what was last programmed but it wont program anything new now. If I read the pic then reprogram it with what was already on, it verifies. But anything new fails. It will not erase it either.

Hi, Gator

Why not simply post your PBP source code .... ???

this kind of post is quasi-unreadable for 99% of forumers - PicBasicPro users included -

to me ... you just forgot to declare your ports as outputs ...

you could have disabled the comparator section ...

AND, to the end ... the default osc setting being XT ... did you ALSO place the XTAL and its caps ??? ...
