void setup(void)

  delay(1000);
  ucg.begin(UCG_FONT_MODE_TRANSPARENT);

  ucg.clearScreen();
  
    // rotation de 90°
  ucg.setRotate90();
 
}

void loop(void)
{

ucg.SetColor( 0, 255, 255, 255);
  ucg.DrawPixel( 50, 20);

}

try

void loop(void)
{
  ucg.setColor( 0, 255, 255, 255);
  ucg.drawPixel( 50, 20);

}
