I was getting a little frustrated at having to add characters to the LED library, so here is a modified character set for the header file ledcontrol.H
it now contains :-
01234567890ABCDEFGHIJLnOoPSTU?+-_=.
letters are included in both upper and lower case, where there is only one the only upper/lower case letter is O! rather than trying to remember which is which!
const static byte charTable[128] = {
