I don't see why not :-). As I mentioned in my
earlier reply tonight, I
wasn't sure if using the normal 7-segemtn decoder helped or not (and
whether it's better to use it for 0-7 or 0-9). Thinking about it,
aren't the 'e' and 'g' segments always on for A-F? That simplifies
things...
Actually, looking at the sequence A-F in the negative sense, many
simplifications come to mind, depending on how the letters are
displayed. I chose "AbCdEF", but there's no reason that "abcdeF"
couldn't be chosen.
Using "AbCdEF", "d" is the only letter where segment "f"
isn't
illuminated. "C" is the only letter that doesn't include "g",
unless
you make the "c" lowercase, in which case, it's always on (as you
observed). "b" and "d" are the only letters that omit the top
segment...and so on.
