GPIOs in Rasplex?

Dev Community Apps & Creations

Hello everybody,

 

I`m trying to add a shutdownbutton to the pi with this howto: http://www.gtkdb.de/index_18_2237.html

 

But I have the problem that the script stopps with the following error:

File "./shutdownbutton.py", line 7, in 
    import RPi.GPIO as GPIO
ImportError: No module named RPi.GPIO

It seems that python is not able to load the GPIO librarys.

 

Does anybody know how i can access the GPIOs with python running rasplex. 

 

At the moment I`m running Rasplex 0.3.1

I don't think openlec has the GPIO module installed... it is a minimalist build...

I use a the RemotePi board to power on/off the raspberry with a remote or locally with a button.

It is connected to the GPIO's.

The shutdown script i use is the following:

#!/bin/bash
# prevent restarting XBMC at shutdown
LOCKDIR="/var/lock/"
LOCKFILE="xbmc.disabled"
# this is the GPIO pin receiving the shut-down signal
GPIOpin1=22
# functions
  add_omit_pids() {
    omit_pids="$omit_pids -o $1"  
  }
  safe_shutdown () {
    touch "$LOCKDIR/$LOCKFILE"
    add_omit_pids $(pidof connmand)
    add_omit_pids $(pidof dbus-daemon)
    killall5 -15 $omit_pids
    for seq in `seq 1 10` ; do
      usleep 500000
      clear > /dev/tty1
      killall5 -18 $omit_pids || break
    done
    sync
    umount -a >/dev/null 2>&1
    poweroff -f
  }

echo “$GPIOpin1” > /sys/class/gpio/export

echo “in” > /sys/class/gpio/gpio$GPIOpin1/direction

while [ 1 = 1 ]; do

sleep 1

power=$(cat /sys/class/gpio/gpio$GPIOpin1/value)

if [ $power != 0 ]; then

sleep 5

safe_shutdown

fi

done

Got it from here

so it should work for you as well.
