Comments: It's good you have it working.  Now you need to fix up this page.
Assume you are writing to someone who wants to know how to use the device.  Show a picture
of it. Note the importance of soldering the display on correctly. Give wiring instructions.
Be specific, where do I wire the power?  Where does the clock go, etc.  How is the voltage
level converter wired in? Show a picture of the wiring.

Clean up Greg's code an put it in your github repository. Include a Makefile
Give me a demo.

Can you have this done in a week?  24-Oct-2012?

Wiring Information

The device relies on the 5V source on the board and to insure functionality an I2C voltage up-converter is used to boost the 3.3V I2C voltage to 5V.

Wiring Diagram

Current Status

The current LED Matrix is fully functional except for a minor issue with alignment of the rows. It is shifted up by one LED and puts the top row at the bottom. The former issues encountered with the device was due to a miss-wiring of the matrix to the I2C Part.
