Usage#
The example of using the GPIO interface is as follows.
# Use root
sudo su -
# Set output to high
echo 1 > /sys/class/gpio/<device node>/value
# Example: echo 1 > /sys/class/gpio/gpio339/value
# Set output to low
echo 0 > /sys/class/gpio/<device node>/value
# Example: echo 0 > /sys/class/gpio/gpio339/value
