AVR graphical LCD test board

GLCD_board.jpg

The board can be equipped with Atmega16 or Atmega32 depending on memory needs. Also it has many other available features that allow to reach various complex applications on single board like 16MHz speed for high speed ADC applications, ISP for fast programming, RS232 communication block, potentiometer adjustable analog reference voltage (AREF) from 0 to 5V, graphical LCD with contrast potentiometer, 3 ADC inputs, 10 I/O pins, reset button, 5V voltage regulator on board. PCB small(100×50mm) single sided without wire strips. There you can also find program demo which KS0108 control library, and all other project files included.

PIC18F2550 KS0108 GLCD Text Test

After working with HD44780displays for such a long time, I’ve decided to try my hand at graphical LCDs. They are cheap and effective at displaying more information than character LCDs, and in a much more concise manner. Most controllerless graphical LCDs can be difficult to work with, however the KS0107/KS0108 controller combination allow for quick and easy programming. For this project, I opted to use the AZ DisplaysAGM1264F 128 x 64 pixel graphical LCD with the KS0108 controller. This circuit is a very simple proof-of-concept that has acted as a stepping stone for further development into more complex programs and displays. When constructed and run, the display will show the complete custom 3×5 character set that I put together for the firmware (using the font format from Cornell University and additional font information from Michael Koss). http://www.semifluid.com/?p=16
