I'm trying to get a button to work on my Beaglebone. I bought MAKE Volume 32 and tried to follow the guide in there.
But when I read the GPIO pin, do I always get 1. I also tried to disconnect everything and is still got 1 from that pin.
I tried to read the value using the file systen as following
echo 70 > /sys/class/gpio/export cd /sys/class/gpio/gpio70 echo in > direction cat value
Here is my setup.
The resistor is a 10k resistor and the button is a arcade push button from Adafruit.
