Shutdown scripts for RuneAudio

The default SSH user name is root, password rune

• Key in :
• cd /etc
• nano irswitch.sh
  
• Copy and paste (use shift+ins to paste in nano) the following text into the editor window
  #!/bin/bash
  # this is the GPIO pin receiving the shut-down signal
  GPIOpin1=14
  echo "$GPIOpin1" > /sys/class/gpio/export
  echo "in" > /sys/class/gpio/gpio$GPIOpin1/direction
  while true; do
    sleep 1
    power=$(cat /sys/class/gpio/gpio$GPIOpin1/value)
    if [ $power != 0 ]; then
      mpc stop
      /srv/http/command/rune_shutdown
      echo "out" > /sys/class/gpio/gpio$GPIOpin1/direction
      echo "1" > /sys/class/gpio/gpio$GPIOpin1/value
      sleep 3
      poweroff
    fi
  done
• Press ctrl+x to exit, y to confirm, enter to save the file
• Key in
  chmod +x irswitch.sh
  
• RuneAudio is based on Arch Linux, in order to run the above script at boot it has to be registered as a startup service :
• Key in
  cd /usr/lib/systemd/system
  nano irswitch.service
  
• Copy and paste the following text into the editor window
  [Unit]
  Description=RemotePi Service
  After=systemd-modules-load.service
  [Service]
  Type=simple
  ExecStart=/etc/irswitch.sh
  [Install]
  WantedBy=multi-user.target
  
• Press ctrl+x to exit, y to confirm, enter to save the file
• Key in
  systemctl enable irswitch.service

The following additional script enables the RemotePi Board to cut off the power, after RuneAudio has been shut down from the on-screen menu.

• Key in
• sudo nano /etc/shutdown.sh
• Copy and paste the following contents

• #!/bin/bash
  GPIOpin=15
  echo "$GPIOpin" > /sys/class/gpio/export
  # execute shutdown sequence on pin
  echo "out" > /sys/class/gpio/gpio$GPIOpin/direction
  echo "1" > /sys/class/gpio/gpio$GPIOpin/value
  sleep 0.125
  echo "0" > /sys/class/gpio/gpio$GPIOpin/value
  sleep 0.2
  echo "1" > /sys/class/gpio/gpio$GPIOpin/value
  sleep 0.4
  echo "0" > /sys/class/gpio/gpio$GPIOpin/value

• Press ctrl+x to exit, y to confirm, enter to save the file
• Mark ir as executable by keying in
  chmod +x /etc/shutdown.sh
• Edit the file rune_SY_wrk located in /var/www/command/ with
  nano /var/www/command/rune_SY_wrk
  
• Find at or near line 600 the text sysCmdAsync(‘poweroff'); and change it to sysCmdAsync(‘/etc/shutdown.sh’);
  
  
• Reboot one time
• After the reboot you can use the RemotePi Board to power cycle RuneAudio.

The above scripts have been tested and are confirmed to work up to RuneAudio 0.4-beta. Although not yet tested, they most likely will work with newer versions as well.
