ponyprog write failed
Hi,
I am new on the forum.
I have a small problem programming a PIC 16F877A. I built myself a ponyprog serial programmer for PIC MCUs and i2C memories. It reads the pic ok, but i cannot write on it. I can write one byte anywhere on the chip, but if i try to write more than one i get a Write failed message. I can read it so the board must be good. (i verified it hundreds of times). For i2C memories it is ok
Can you please advise me? What could go wrong?
Thank you very much!
