is there a way to make the custom key matrix read by keypad.h support more than single characters? as i have 32 keys, i have 1-8 and then alpha characters, but i am having a horrible time constructing the rest of the code because of the letters.
most of the problem is i don't know how to construct comparative statements that only read one row of the keypad, eg: 1-8 changes the "currentbank" var but, i don't know how to limit the "customKey" return to only one set of numbers.
ugh. i don't know how to explain this clearly :-/
