Posted - 01/15/2008 : 18:51:35 I have the enhanced JDM programmer and I'm having trouble programming the 16F628A. I've successfully programmed a 16F877A and a 12F675, so I know the programmer is ok.
PicPgm finds the programmer and identifies the PIC as a 16F628A. When I try to program, it says it works, but verify fails. Reading the chip shows all 0's. I can erase and if reverts back to 3FF.
I've tried PicPgm, WinPic800 and IcProg with similar results.
Anyone have any suggestions?

Yes, the code protect was set in the sample hex file I downloaded to test. The program I was using didn['t make it clear until I checked with another.
I turned off code protect and it is working fine now.
