I am driving an 40x4 LCD with my DSK, but i use a cpld to drive it. I don'
t know if emif timings are correct to drive an LCD directly. Using a CPLD allows
you to create an 8 bit port, and you can drive it like many people do from the
PC's LPT port. It is quite simple and you can find a lot of code on www. If
you use an 8 bit port, you have to do 4-bit data interfacing to the LCD (i am
assuming it is a common HD44780 based LCD).
For faster developement i suggest you to use the GPIO port of the DSK. Check how
many lines of it are available on the DSK connectors and drive the LCD from
there(4 or 8 bit if enought lines are available).
