Need Verilog code to display characters on LCD module

[sushantm]

Dear all,


I want to start a lcd display I had studied its datasheet got the pins and specified words the RS , RW and DB0 to DB7 signals..but i am not getting exactly what to do? any one can provide me simple verilog code to display hello or a single letter 'H'.Please help me. I am working on Altera's Cyclone III Fpga Devlopment Board.


Please helpo me out.





Thank's

Re: Character LCD Module

study the lookup table for lcd display
which gives more information on displaying each character on lcd

RS is register select pin that takes 0 or 1 as input and is used to configure LCD in command mode or data mode.

RS=0 command mode. it means that any data sent to LCD will be treated as initialization command.
RS=1, data mode. it means that any data sent to LCD will be treated as data to be printed on LCD.

RW is read or write register that takes 0 or 1 as input.

rw= 0 data can be sent
rw=1 LCD is busy, wait till operation is over.

En is enable. it is used to send the data from controller to LCD internal registers. it acts like a gate that opens and allows the data or closes the gate.
If en=1 then datafrom controller moves into the registers of LCD.
of en=0. data stays on the port pins and waits till en goes high.

en should be given as a high to low pulse. if 1 msec.
