Probleme Touchscreen Arduino Mega + TFT ILI9481 480x320

Salut. Am și eu o problemă cu ecranul TFT 480x320 (ILI9481 driver). Acesta este conectat direct la Arduino MEGA, am instalat bibliotecile UTFT și URTouch. Când folosesc unul din exemple date, afișează perfect totul, dar touchscreenul nu funcționează. Ar mai trebui să instalez ceva vreo bibliotecă sau vreun driver? Vă mulțumesc.
Codul este următorul:

// This program is a quick demo of how to use the library.

// This program requires the UTFT library and a display
// module with at least 320x240 pixels resolution.
//
// It is assumed that the display module is connected to an
// appropriate shield or that you know how to change the pin
// numbers in the setup.

Cele 2 librarii sint compatibile cu acest model ?
Incearca si alte librarii, eu am gasit cel putin 2 (la una scria clar ca e comatibila, cealalta avea niste producatori, n-am stat sa caut exact modelul)
Conexiunile sint facute corect ?
Mai verifica o data.

Da, conexiunile sunt bune, ecranul fiind pus direct pe Arduino Mega, la pinii 22-54. Sunt compatibile, am văzut videoclipuri pe yt cu librăriile acestea, și functiona ecranul touch.
