The Alpha

It's kind of a core feature that one can enter alphanumeric PINs on the device, so the time is ripe to redo this routine.

Problem is, the keypad is completely different code-wise, so I'm afraid I'm going to have to implement a version of multitap myself ab initio.

Ahhahahahaaaaaaaaa!

Ok, let's just expand the case(){} statement to include all the letters and the capitals. MAYBE can just pass the time that the key is pressed as an integer and add it to the int result that drives the case(). In any case (ha) the statement is set up so 0-11, then add 20 (so no overlap so it rolls 20-31, then 40-51, then 60-71. Caps are the entire alphaspace but with 100 added, so 120-131 etc.

So looks like I ended up going a completely different direction, but it WORKS! Plus it's really easy to add more chars, such as the 9YZ!@#$......

That's in Arduino, now time to integrate that to the main code.
