Hi Andrea, have you tried the UTFT library with your 2.2 TFT LCD HX8340B yet? Which display is it?
I am guessing it is the adafruit 2.2" 18-bit color TFT LCD display with microSD card ID: 797. I am a newbie to microprocessors and need a LCD display for a radio project and thought I would introduce myself to arduino by programing this display. Thanks Simon
