MCP23017 input expansion

[kenzo]

Hi All,
I created a driver based on Adafruit Retrogame which can expand Raspberry GPIO. Thus you can buid your own arcade station with 2 players using 6 (or more) buttons per player.

Hope you enjoy it !
See ya

I also attached circuit schematic in order to help people connecting MCP23017 with Raspberry
