Thanks Rob.. I'm sure that is the problem I have with the excel sheets.. I have Microsoft office here somewhere and will be installing it shortly on my computer. Then I can do some serious curve generation for my chips.
Did you change output pins on your edited Nyemi code? I tried your code and it programmed ok but doesn't function when I plug the 16f628 chip into the timer board..no output at all. Maybe I missed something in the compiler?
