I have the old spreadsheet file for you Charlie.. I'll send you another email with it attached. Just sent you the hex file of the new code but it only works on a 16f628A chip. While assembling it with the MPlab program, it asked for a target chip number. I only had 16f628a chips sitting here and wanted to try it out so that's what it was assembled for. I'll do another one for us with the 16f628 chip as a target and send that to you also. When I can, I'll try posting both hex files on here for everyone to download that's interested.
I use Picprog4u to write to the chips and it gave me a warning when I tried the 628 instead of the 628a..needless to say it didn't work when programmed cause it had the chip internal info for the 628a in the hex file. Oh well live and learn I guess.. Have to erase that one and try again with the right code.
