[Gumstix-users] Adding a push button

[Brian W. <bw...@ir...>]

I am adding a button to be able to enter low power mode (umount CF, disable 
ethernet, turnoff LCD, etc) I am using the Connex 400 XM board + NetCF + 
breakout GS. If I understand correctly, I should be able to use GPIO 42 
(BTUART) as my input with:
echo "GPIO out clear" > /proc/gpio/GPIO42
and then controlling events via the gpip event montior.

Is this correct? Also, Is there an easier/better pin to use? IE can I more 
easily use the pads on from the breakout GS (I2C/PWM) as my  GPIO? I am a bit 
confused on this point.

Thanks
Brian
