These set of examples use the Character LCD Screen to display information in different ways.

Open the LabVIEW project file for this example. Opening any of the VIs before opening its project may lead to
failures.

In order to use the first example the file “PadWrite.vi” must be compiled before attempting execution.
This is done by opening the VI and then pressing the run button while holding the "Ctrl" key on your keyboard. 
Once compiled open the file “PadWriteHost.vi”. Run the VI and LabVIEW will download the example to the FPGA.
When the “Init Done” light in the Front Panel window turns green the LCD initialization will be complete
and ready for user interaction. 
Try using the keypad on the Front Panel window to show different letters in the screen.
Using the controls on the Front Panel of the Targert VI will cause faulty execution.

Running the file “WriteToDDRAM.vi” will display a message on the LCD Screen using predefined characters on the DDRAM memory. 
“WriteToCGRAM.vi” will display custom characters in the CGRAM memory. These VIs do not requiere a host VI.

For more information on the character memory mapping refer to the  Xilinx UG230 Spartan-3E Starter Kit Board User Guide 
Chapter 5: Character LCD Screen

*As specified by the Xilinx UG230 Spartan-3E Starter Kit Board User Guide the examples use the LCD_RW signals 
and four of the StrataFlash data lines, for this reason, the StrataFlash is disabled so it can not interfere with LCD operations.
