Through the code example it is straight forward to control the LEDs.
I cannot however find any information on how to control i.e. the GPIOs (or other connectors).
Trying to follow e.g. this guide lets me read values (through “cat /sys/class/gpio/gpioXX/value” ) but I cannot write (I get “permission denied”) even though direction is (preset) to “out”.
Can anyone shed some light on this issue?
