Honored ContributorThe touch screen is hooked up to more then one component in sopc, because you have to control it's functions independently. So you have got one module for showing a picture on the lcd, one interface to access the touch data and an i²c component to set different configuration values. See the LCD-Part as three components.
A good hint is to look into the description from Terasic under http://www.terasic.com/downloads/cd-rom/ you can find ltm and mtdb. There you find all the hints for working with the lcd. The problems I had while working with the neek were, that all data passes the MAX-Chip and because of that you can't normally use a VIP-VCO for Output. You have to use the LCD-Controller Altera provides. There is also a good connector out here in the Forum to get VGA working, see the example here http://www.alteraforum.com/forum/showthread.php?t=6118 That can also be adepted to LCD, perhaps. I hope that helps you a bit. Good luck.
