help me display text LCD on DE2.....

Most 2x16 LCD displays are based on the control commands of the hitachi hd447980 (http://www.electro-tech-online.com/attachments/datasheet-parts-requests/7212d1139693600-help-hitachi-hd44780-16x2-lcd-data-sheet-hd44780u.pdf).

The easiest is to control the LCD display from an embedded processor like Nios II.

But you can also directly drive it from a HDL description.

http://www.edaboard.com/ftopic348429.html has a design in VHDL.

Hope this helps...

Hi trantuan25187,

you can also have a look at http://www.fpga4fun.com/textlcdmodule.html .

Besides the LCD controller, this site also has many other interesting and well documented design examples.
