I have a strange problem with a pic 16F877A
I’m using my K8076 programmer to program it.
I have 2 pics. One of them reads and writes perfectly, but the program loaded into it never starts running. The other one only starts up when running in debug mode. I tried various programs, also the blinkled supplied with the K8076 kit, but still the same problem. I also tried various configurations on the MCLR pin, still the same.
Only when i use the fuses Powerup-timer and Debug, one of them works.When i load the same problem, but only select Powerup-timer, the program never starts.
Any idea what the problem can be? I have made various project with PIC 16F648A,pic 12F675, so I’m familiar with the needed hardware and programming pics.
thanks,
Niels
