Hi,
Of course, xmega (3v3) is not diectly compatible with LCD in 5V.
i use some "translator" 74VHC1VT50 and it's works perfectly.
In attachement a part of sheet of exemple. (sorry the wiring is to be according with the CAO).
4 X 20 lcd
i use same chip to interface other moduleS in 5V (RFID reader).
