I have a problem reprogramming a 16F818 with my Wisp628, apparently after enabling the watchdog (not LVP). I anyone can tell me what could cause that I would be very gratefull. But to check the chip I dug up my ICD2, installed MPALB 6.5, inserted the 818 in my PICDEM 2+ board and connected it all. Using MPLAB I can read the chip, but it reads all 0's. I can import a .hex file, program it to the chip, verify it without error message, read the chip, and I get 0's again. I can disconnect the PICDEM board, and still program and verify without errors! Now what the heck is going on? I did not even wave a dead fish...
