UNO Change Font
In this simple simple example we use one Arduino UNO connected to the ArduTV and use a different font (Greek) from the ones just provided as default.
The code of the Example
#include <ArduTV.h> //ArduTV Library to be included
ArduTV HDMI1(10); //Set the CS pin for ArduTV
u8 FONT[8]={0,255,0,255,0,255,0,255};
u8 font8x8_greek[57][8] = {
