This is a simple interface that I have implemented to test the LCD device when I got it for the first time. I simply used the documentation provided in the issue of Everyday Practical Electronics magazine, February 1997. LCD can be easily controlled with any device. If you are using Micro Controllers then it is very easy to use. You can get the free samples of Micro Controllers from MicroChip and Maxim Dallas companies. I have provided the software (with source codes) that I have developed with Delphi 6. If you want to try it simply connect the LCD panel as in the above diagram to the PC parallel port, connect pin 1 and pin 2 to power supply, connect pin 3 to ground for maximum contrast and run the software.

Parallel port information can be taken at beyond logic site.
 

Software developed for this experiment. If you need further assistance let me know.

Some times you may need to slow down the commanding speeds to the LCD device to perform its proper operation, then you have to edit my source code and compile it again. But if you still don't get the correct output, then this software may not be compatible with this LCD device

However writing routines to any LCD panel is as simple as this project. Unfortunately my LCD panel does not have a back light. But  connecting the pin 15 and 16 to the power supply you can turn on the back light if available. (Check for the Anode and Kathode of pin 15 and 16.).

Application software is written in Delphi 6. This is a very good language for such activities and you can learn more about Delphi from the site Torry.
