The only ways I can think of, is to verify the code on the chip with the HEX file that it was programmed with, using the programmers 'verify' command. If the chip is code protected, you should read back the program contents after you have programmed it and save it to a file. The data in this file can be used to verify the software in code protected chips. Regards Tony Just when I thought I knew it all, I learned that I didn't.
