Looking for Simple LCD DISPLAY source codes

Hi everyone,

i'm a new guy for this forum, and i looking for a sample and simple LCD VHDL codes for display characters on @ltera UP3 board! this several days, i just exposed to the VHDL and the UP3 board. i not familiar about the codes as well, hopefully someone willing to give me a hand. thanks a lot..........

    http://users.ece.gatech.edu/~hamblen/up3/designs/up3_clock.zip (http://users.ece.gatech.edu/%7ehamblen/up3/designs/up3_clock.zip) has a Quartus project which does exactly what you want it to. You can also try some cool LCD display programs using Nios II.

    hello vizziee,

    thanks for ur help..... but the source code seems too difficult for me to understand it. actually i only need a really simple source codes to display the character on LCD. i just want to display a few words on the LCD!

    example: " welcome to the world"

    and hopefully someone can tell me where i can get the reference about the LCD character too. thanks......

    If you find it difficult to code in HDL, try doing it using Nios processor. In that case, use a sample project of NIOS and code in C (in fact, there is an LCD Display example already there in NIOS examples). The code is very simple in this case.

    Try to develop a simple FSM that generates the signals timing to write commands and data to the LCD.
