DOH! I had a detailed question but it got cleared. So here's the short-short version.

Has enybody included a 4x4 keypad routine in with DT's instant interrupts? It would most likely use port B change to trigger. I found forum references to keypad and interrupts but since I'm using the elapsed timer routine anyway I think I should stick with the "instant interrupts" technique. Can it be done with a change in variable value?
