Spartan3E LCD Driver Info:

---------WHAT IS IN IT----------

There are 4 files in this module:

1) LCD_IF.vhd: This is the top level LCD interface file. It has 4 4bit inputs,
which we want to show on the LCD.

2) kcpsm3: This is the picoblaze, soft processor.. It helps drive the LCD on 
Spartan3E by dealing with complicated initializations, timing, etc.

3) lcd_dr: This is the ROM file created using the Xilinx's assembler.. It 
communicates with the kcpsm3, and provides the necassary instructions to the 
soft processer. 

4) LCD_IF.ucf: This is the .ucf file where we assign the package pins. 


---------HOW TO USE------------

In order to use these files you need to do the following:

a) Copy these files into your project space, and add them to your project. 

b) Instatiate a copy of the LCD_IF module.

c) Connect your 4 4bit display values to the inputs of the instantiated
LCD_IF instance.

d) Also, you will need to remove the existing .ucf file and merge it to your 
top level .ucf file.
