Hi fungus,You mean to say that it needs something else? Do you maybe know what that is?
From what is shown in the loop in the second sketch
int8_t NumTab[] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};//0~9,A,b,C,d,E,F
int8_t ListDisp[4];
it seems it is a char.
I didn't say it wasn't a char, I said it wasn't ASCII. Looks like they use
the value 0 to display a '0'.
