These routines manages the 128x64 Graphic LCD based on the Samsung KS0108 or Hitachi HD61202 driver.

The available functions for the moment are :

• Initialize the LCD
• Clear the LCD
• Display a 128x64 picture
• Set the cursor position
• Display a string
• Display a value
• Draw a rectangle
• Draw a circle

I've planned to design a function to draw lines, to draw 2D graphics and a rolling menu. It's currently in development.

You can download the code here (ZIP, 5Kb).

You can download the fonts here (ZIP, 4Kb). I've coded four fonts :

• System3x6 (from char 32 to char 96. There is no the lower cases)
• System5x8, (from char 32 to char 128)
• System 7x8 (from char 32 to char 128)
• Courrier8x12 (from char 32 to char 57. There is only the numbers here)

To draw pictures and fonts, I've used the software FASTLCD by Bojan I. - MICRODESIGN. You can download the version 1.20 here (ZIP, 82Kb). If you have a more recent version or an other tool, please tell me.

You can download the following datasheets

• GMD12864A (PDF, 199Kb) : this is the LCD datasheet
• KS0108 (PDF, 158Kb)
• HD61202 (PDF, 77Kb)

I will add some pictures of the LCD in a few days...
