EV3 Buttons

The 6 buttons on the EV3 are connected to GPIOs.

Button	GPIO	Description
0	7-5	Up
1	1-13	Enter
2	7-14	Down
3	7-12	Right
4	6-6	Left
5	6-10	Back (ESC)

##Device Driver We are using the existing gpio-keys driver. This causes the buttons to function as regular keyboard keys. Key mapping is defined in board-legoev3.c. Currently the back key is mapped to ESC, but @dlech wonders if it might be better mapped to Backspace.
