I try to manage GPIO12: echo 12 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio12/direction echo 1 > /sys/class/gpio/gpio12/value echo 0 > /sys/class/gpio/gpio12/value But the voltage at J12 pin 9 is not changed. Where an error? |

gpio 12 is reserved for UART CTS Try another GPIO like 23,22,21,20,19,18,17,16,15,1 |
