Matrix Keypad routine

[T.Jackson]

Huh? Lookups have their place (and I love them when needed) but to say PICs are not equipped for calculations is just plain silly.

I didn't say not equipped - I said not as well equipped. And, I'm more so referring to something that's more so "hard coded" over calculations. When I say hard coded I'm talking about something that's direct as in (a = 100) Vs (a = b x 10 / 2) No prizes for guessing which is faster and uses less resource.
