strange behavior on my prog !

BTW what does the "static const" declaration do exactly?

"static const byte FontLookup [][5] ="

static : that mean the compiler attribute a fixed adress in ram
constant : that doesn't vary along the prog !
byte : this is the type of your constant...

i think the solution of your prob, is the same of mine...
we have to wait a bit more for a solution.
put your patience under your foot and wait ::slight_smile:

my two pences...
