Honestly, this would be a trivial exercise in PIC programming - unfortunately I'm just too busy to get too involved right now. If no-one else does it, I might be able to do something next month when things are a bit quieter...

Actually, this is an ideal challenge for anyone who has been wanting to get into PIC programming, but has been lacking an idea for a simple "first project". To get you started, you can download a simple set of 4-bit counters from my WWW - there's even a version that deals with switches for up/down. You'll need to modify the code, because IIRC the counter wraps around from 0 to 15...

Good luck!
