Touch Shield Slide or stealth Help.

Hi all,

I am using an Arduino Touchshield Stealth right now to develop a project, however the end product is supposed to be a 5in LCD display so i was wondering how am i supposed to port it over?

i went to check out what the stealth has and it seems to me its all controlled by ATMEGA645 mico controller, and since i am really rather weak in hardware and stuff i was wondering if it is actually possible to buy an ATMEGA645 chip, do the relavent connection and the LCD will work accordingly or will assembly language be involved?

Please advice! =( its driving me crazy heeh..

Thanks alot

Jonathan
