It's a fresh raspbian installierbar, with the only Addition of 1wire and snmp.
I'd expect /sys/class/gpio/gpio<pinnumber>/value there.
@alsternerd I'm not sure what you are trying to do, but did you call "echo «pinnumber» > /sys/class/gpio/export" beforehand?
And maybe you need to change /sys/class/gpio/gpio0/direction to "in" or "out", too.
The package "sysfsutils" can help to make this permanent and assign user permissions, if needed.
@mehdorn Hm, I did try to set the pins through /boot/config.txt with
gpio=18,20=pu,ip ( pullup, input )
@mehdorn This seems to work, thank you.
SO I do have to choose the echo and sysfsutils options over /boot/config.txt.
I hoped this had to be done with a one-line. :D
@alsternerd I prefer the sysfs variante over /boot/config.txt, as it works with Olimex, BananaPC, …, too.
