The sample Verilog will take care of initializing the driver chip on the LCD board. It has a power up init protocol similar to a DRAM chip. Then it sweeps through the ASCII data you provide one character at a time.

The displays have fancy features for cursors, changing character sets, etc. If you want to use that stuff you will need a more detailed control state machine.
