    gpio export 27 in
    gpio edge 27 both
    
    gpio export 17 in

    sh -c "echo '1' >> /sys/class/gpio/gpio22/active_low"
    sh -c "echo '1' >> /sys/class/gpio/gpio27/active_low"
    sh -c "echo '1' >> /sys/class/gpio/gpio17/active_low"
    sh -c "echo '0' >> /sys/class/gpio/gpio22/active_low"
    sh -c "echo '0' >> /sys/class/gpio/gpio27/active_low"
    sh -c "echo '0' >> /sys/class/gpio/gpio17/active_low"
    sh -c "echo '1' >> /sys/class/gpio/gpio22/active_low"
    sh -c "echo '1' >> /sys/class/gpio/gpio27/active_low"
