I joined in this quite late, but on the original bargraph code posted by Darrel (and also the interrupt code posted elsewhere) I have one thing to say....WOW Darrel. GENIUS.. BOTH of these snippets have saved me hours of work on a project I'm working on.

I needed to poll an array of front panel switches every few milliseconds AND service a bargraph update AND change the frequency of a HPWM signal all at set times, I was in the process of writing an RTOS for the PIC to allow me to use queued commands executed on a priority/time basis, then these two pieces of code went live.

OK, you killed my six months of work on the RTOS, but I'm not complaining. Everytime I see a new posting by you I just KNOW it's gonna be soething that makes my life that little bit easier.

A huge thanks and keep up the excellent work.
