Pour ajouter le 2ème fichier, Aller sur Sketch, Add File

#include <Wire.h>
#include <I2C_LCD.h>

I2C_LCD LCD;
extern GUI_Bitmap_t bmTuzki;       //Declare bitmap data package.
uint8_t I2C_LCD_ADDRESS = 0x51;  //Device address configuration, the default value is 0x51.

void setup(void)
{
    Wire.begin();         //I2C controller initialization.
