> I have a noppp that I built for my 16f84a. To program a 16F628 using the NOPPP you can try the free software (FPP) available here: http://www.man.ac.uk/~mbhstdj/piclinks.html If you use Windows run FPP and select the TOPIC setting. If you prefer a Windows DOS box version use a command of the form "fpp -w0 -h8 -t10 -f628 file.hex" or if you have a DOS-only machine use a command of the form "fppdos -h8 -t10 -f628 file.hex".
