Tom, This is the way my JW devices act when they go out; I can't make them work with any amount of UV exposure. I don't know of any way to revive them; someone once said to put them in a oven at a certain temp for a certain period of time, but after this even if they did work I wouldn't use them for development. Your message reads like the part was brand new. Was this the case? If so, just send if back, as they should come new blank. -Todd Peterson

As I remember,...Watch your configuration bits, if you are using MPLAB and the default of an erased chip is different then what you have your system set up for, you will get an incorrect read. --- On Mon, 3 Feb 1997 12:27:57 -0800 Carol & Tom Tumilty <tumiltyKILLspaminterlog.com> wrote: I have a pic16c54jw that i bought and when i went to program it wasn't blank.
