Adafruit: 8x8 Blue LED Matrix Panel
This Mini Project dealt with using Adafruit's 8x8 Blue LED Matrix. The source code they provided is written for Arduino. However, I am using the Beagle Bone instead. Luckily, Dr. Yoder has provided an example program called matrixLEDi2c.c that interfaces the Beagle. You can download or observe his source code here: Dr. Yoder's github repository.
