What should happen whith the GPIO when I unexport an output pin? I did the following:
$ echo 89 > /sys/class/gpio/export
$ echo “out” > /sys/class/gpio/gpio89/direction
$ echo 1 > /sys/class/gpio/gpio89/value
$ echo 89 > /sys/class/gpio/unexport
After the last command I was expecting that the GPIO pin was in high impedance or set to input but the signal remains high. It’s correct?
