4-Digit Display Error

Using Arduino LEDs and Multiplexing
8

Hi there,

Yeap. It seems it used 0 to 15 as hex as it ends up printing from 0 to F.

But the key to understanding both:

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];

is really understanding what int8_t stand for. Which I don't have a clue about. :frowning: I am guessing it is not arduino lingo per se, but C.
