That is a nice board, I have one. There is code in OBEX for the 17 segment display but it uses up allot of pins. I am trying to get a 16bit I2C bus expander working to use all digits but it will be a while before I get to it. Right now I have the board wired up as a demo board, and waiting to get a flat tire fixed so I can go get a keyboard and mouse for it.
Download the schematic for the board, The switches and buttons are pulled up to 3.3V. That threw me of on a few projects that had them pulled down when I first got the board.

I am going to be using the 4x4 matrix keypad, two PCA9555N I2C expanders, and code from http://forums.parallax.com/showthread.php?102475-PCA9555-IO-Expander-Driver&p=719130&viewfull=1#post719130 to try and try get it all working. Once that is done I will try to get a 24-Bit I2C expander working with the display, but the IC's I have are too tiny for me to work with at the moment.
