I am programming a 16f877 with PicBasic at the moment programming size is just over 4500 words, I use Bonny Gijzen Pic Prog.. and the JDM programmer all seems to work OK .
As I write the prog I keep testing what I have written erasing the PIC and reprogramming. But something strange appears to be happening.
I can erase/re-program perhaps 10/15 times all OK then for no reason everthing seems OK the PIC programs and verifies OK but does NOT WORK (Just as though it has not programmed) try a different PIC 16f877 works OK Let the first PIC rest ......back on its foil next day works OK.
Question can the PIC be stopped from doing this.
