Attached a Verilog sample LCD driver.

It initializes then continuously updates a 16x2 LCD from a bank of wires. The wires are ASCII chars, "Hello there 32 chars ..." etc.

The timing can be a little bit finicky. I had to add some proper timing constraints to the output signals to get it working on a Cyclone III DSP board.
