I'm upgrading the interface that uses the 8 pin PIC and actually studying another two slightly more advanced designs.So is your new design going to use a differend PIC with more I/O pins?
If you're interested, I've attached the source (assembler) for the 12F635 backpack as well as the source (also assembler) for the 16F1823 on that prototype board. This is the old software and, as I mentioned, probably not very useful for PBP users who are used to having all those wonderful LCD output formatting capabilities.
Happy Holidays! Mike
