Please Check first this for the LDC Pin_ -Out. via Spartan 3E Board . http://www.xilinx.com/support/documentation/boards_and_kits/ug334.pdf So you need to get the source code for LCD via FPGA ... Good Luck.

http://www.cosmiac.org/pdfs/09Tutorial6.pdf This is the hint for source code via FPGA to LCD. May other users help to get the source code. But first you must know the SPARTAN 3E PIN-Out via FPGA<-->LCD. see (UCF) File.. Do you use VHDL or Verilog? . May other find the ORGINAL SPRARTAN 3E Stock Firmware Reference File for the Project on Spartan 3E Board. Greetings Holger.

Here is a Video that shows how LCD via FPGA works . And you can watch the part of the source code. http://www.youtube.com/watch?v=2_yxS-M7HKU I will look for the orginal SPRATAN 3E source code and Project File, wich is on the Board when its delivered. Can anyone find it ? Greetings Holger.
Program LCD on Spartan-3E, Verilog/FPGA (TestLCD) Trap: Please notice exact the sfr_bit set fixed to 1 to disable the Stata FLASH Device wich is also part of the´shared BUS via LCD. See code review , see FPGA OUTPUT-PORT SFR == 1. Link: http://www.youtube.com/watch?v=lQ6YKQt6Rz4 Greetings Holger.
i am using Spratan 3an board using VHDL !! i made code but its not working
Can you put the orginal Stock Software thats delivered with Board as bitfile on, that you can see if the LCD Hardware is working anyway ? Trap: adjust contrast through trim pot. (may you Trim-Pot is not ok) How to Interface 2x16 LCD with Spartan-3an FPGA Link: http://www.pantechsolutions.net/cpld-fpga-boards/2x16-lcd-interfacing-with-spartan-3an-fpga check the Pinning there. See map There is the VHDL Code you can download after registration. Greetings Holger.

ModelSim Simulator?. Here is the code for VHDL -- Description: 16x2 Text LCD controller for 8bit Mode -- used on the Spartan-3A Starter development board http://www.mikrocontroller.net/attachment/highlight/49310 But keep the special Pin at the Strata Flash at permanent High. It is shared with the LCD Bus. -------------------------------------------------------------------- Greetings Holger.
