Following examples are provided with libgpiod https://github.com/brgl/libgpiod : |# Toggle a GPIO by name, then wait for the user to press ENTER. |$ gpioset --mode=wait `gpiofind "USR-LED-2"`=1 |# Pause execution until a single event of any type occurs. Don't print |# anything. Find the line by name. |$ gpiomon --num-events=1 --silent `gpiofind "USR-IN"` Used names was taken from RIoTboard schematics, version 1 (2013.12.07).
