Hi rngd, If you have a suspected dead PIC try erasing it several times, this sometimes works.

Rngd,
For times like these (suspect RIP pic) I load it with a very simple LED blinky program which flashes all the ports on and off. If that works than I know that the pic is OK.
;P

Amazing how it always goes back to ol' blinky isn't it?Originally Posted by Squibcakes

Ya.. It's a good basic beginner, and testing code

If you did something to the Vref pin, you only may have messed up the analog circuitry. I would do an LED check of the specific pin you overvoltaged. Also was the voltage directly on the pin or through a series resistor? The resistor would have probably protected the pin.

Overvoltage with no current limiter is more or less a bulletproof way to fry a pin on a pic. I've never seen the entire pic beeing fried from it though.
