Setup as output
echo "23" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio23/direction
echo "1" > /sys/class/gpio/gpio23/value echo "0" > /sys/class/gpio/gpio23/value
Setup as input
echo "23" > /sys/class/gpio/export echo "in" > /sys/class/gpio/gpio23/direction
cat /sys/class/gpio/gpio23/value
echo "23" > /sys/class/gpio/unexport
Or:
gpio -g mode 23 out gpio -g write 23 1 gpio -g write 23 0
