  • The gpio-hammer is used from userspace as an example of how
    to retrieve a GPIO handle for one or several GPIO lines and
    hammer the outputs from low to high and back again. It will
    pulse the selected lines once per second for a specified
    number of times or indefinitely if no loop count is
    supplied.

    Example output:
    $ gpio-hammer -n gpiochip0 -o5 -o6 -o7
    Hammer lines [5, 6, 7] on gpiochip0, initial states: [1, 1, 1]
    [-] [5: 0, 6: 0, 7: 0]
