Sample Atmel AVR Code for the
Spark Fun Nokia-like graphic color LCD

Last Updated August 21, 2006

The following sample code is distributed under the GNU General Public License. It comes with no warranty or support.

This sample code (124k ZIP, 8-21-06) is designed to control Spark Fun's Nokia-like graphic color LCD with an Atmel AVR microcontroller.

The sample code was written for an Atmel ATmega644 AVR microcontroller, but should run on the mega16, mega32, mega128, etc.

The code uses C++ classes. If you have ever forgotten to set the direction register for an output, or neglected to call a setup function to initialize a counter, you'll appreciate that the class constructors automatically take care of all the setup required for each object.

Some tips for using the code...

• Read the readme.txt included in the ZIP. It contains lots of useful information!
• Look at the code in main.cpp for examples of how to use the features in the LCD code.
• For files in the "lib" (library) folder, look at the code in the .h files to see what each object can do. You shouldn't need to modify the .h or .cpp files in the lib folder.
• Read the comment at the beginning of "makefile" to see what commands you can specify.
• Use the "make setfuse" command to ensure that your microcontroller's fuse bits are set for the sample code (e.g. 8 MHz processor speed). You only need to do this once; the fuse bits are persistent.
