I am trying to program a 16F877 from a hex file using my P16PRO parallel port programmer. I can't get it to program with either ICProg or Picallw software, and I checked that I have the latest versions. Code protect is shown as off when I open the hex file. I know my programmer works because I used to use ICProg all the time to program 12F629s. I just downloaded WinPicProg 1.91 but do not know which options to set for a P16PRO programmer, so I have not tried it yet. Any ideas as to what my problem may be?
