Function

Control single RGB

/*
    Parameter:
        indexOfLED: 0 ~ 11
        r, g, b: 0 ~ 254
*/
void Led(int indexOfLED, int r, int g, int b){
  Wire.beginTransmission(FACE_JOY_ADDR);
  Wire.write(indexOfLED);
  Wire.write(r);
  Wire.write(g);
  Wire.write(b);
  Wire.endTransmission();
}

Read the offset of each direction

void get_joystick_offset(void){
  Wire.requestFrom(FACE_JOY_ADDR, 5);
  if (Wire.available()) {

    y_data_L = Wire.read();
    y_data_H = Wire.read();
    x_data_L = Wire.read();
    x_data_H = Wire.read();

    button_data = Wire.read();// Z(0: released 1: pressed)
}
