Hi. I use a p16pro programmer with picall software. I can program a blank pic but once it is programmed I cannot reprogram = it at all. I get a fault1 error in the programming software. I suspect that it is probably running in the programmer since it is = using the internal Rc oscillator. this is somehow preventing it from going into programming mode Has anybody else encountered this? what am I doing wrong?
