Everything you need to know about the onboard LCD

NOTE:  I've cross-posted this to the Xilinx Boards & Kits forum here, where this subject is customarily discussed.

 

This is a 'how to use the LCD' question, not a Spartan-3e question.  Here is the information you need:

 

1.  The datasheet for the LCD controller, the Hitachi HD44780.  Here.

The various commands and modes, including character shifts, are described in the controller datasheet.

 

2.  Two-part 'how to use' article, published in 1997:  part 1  part 2

Creating user-defined graphics is covered in part 1

Using nibble (4-bit) mode is covered in part 2.

 

3.  Here's a useful 'how to use' page.  Here.

 

4.  Here's a nifty page for building custom characters for the HD44780.  Here.

 

5.  Here's an online (Java) emulator for an HD44780 LCD !! (also downloadable for offline use)  Here.

I haven't tried this, but it looks very useful for the newbie.

 

Hope this helps.
