A linux sysfs gpio wrapper impl in QT for systems like the Raspberry PI.
A test with pin11 (gpio 17)
echo 17 > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio17/direction
echo "1" > /sys/class/gpio/gpio17/value
echo "0" > /sys/class/gpio/gpio17/value
# Or the same but with high/low and not in/out
echo "high" > /sys/class/gpio/gpio17/direction
echo "low" > /sys/class/gpio/gpio17/direction
