Shutdown scripts for moOde Audio
The default SSH user name is pi, password moodeaudio
The rest of the instructions are the same as for Raspbian, moOde audio is based on Raspbian.
-
Key in :
cd /etc
sudo nano rc.local -
Copy and paste (use shift+ins to paste in nano) the following into the nano editor window, just above the last line (before the line exit 0)
(/etc/irswitch.sh)& - Press ctrl+x to exit the editor, y to confirm, enter to save the file
-
Key in
sudo nano irswitch.sh -
Copy and paste 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 [ $power != 0 ]; then
echo "out" > /sys/class/gpio/gpio$GPIOpin1/direction
echo "1" > /sys/class/gpio/gpio$GPIOpin1/value
sleep 3
sudo shutdown -h now
fi
done - Press ctrl+x to exit, y to confirm, enter to save the file
-
Key in
sudo chmod +x irswitch.sh
The following additional script enables the RemotePi Board to cut off the power, after moOde audio has been shut down from the on-screen menu.
- Key in
- sudo nano /etc/shutdown.sh
- Copy and paste the following contents
- #!/bin/bash
REBOOT_GREP=$(systemctl list-units --type=target | grep reboot)
SHUTDOWN_GREP=$(systemctl list-units --type=target | grep shutdown)
if [ "$SHUTDOWN_GREP" ] && [ ! "$REBOOT_GREP" ]; then
# the condition above makes sure, that the shutdown sequence is not run on reboot
GPIOpin=15
GPIOpin1=14
echo "$GPIOpin" > /sys/class/gpio/export
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$GPIOpin/value
echo "$GPIOpin1" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio$GPIOpin1/direction
echo "1" > /sys/class/gpio/gpio$GPIOpin1/value
sleep 4
fi - Press ctrl+x to exit, y to confirm, enter to save the file
-
After saving the file, mark it as executable with
sudo chmod +x /etc/shutdown.sh - Key in
- sudo nano /etc/systemd/system/irswitch2.service
- Copy and paste the following text into the editor window
[Unit]
Description=RemotePi Board Shutdown Service
Before=multi-user.target
Conflicts=shutdown.target
[Service]
ExecStart=/bin/true
ExecStop=/etc/shutdown.sh
Type=oneshot
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target - Press ctrl+x to exit, y to confirm, enter to save the file
- Key in
sudo systemctl enable irswitch2.service - Reboot one time
- After reboot you can use the RemotePi Board to power cycle moOde audio
The above scripts have been tested and are confirmed to work up to moOde audio 4.4. Although not yet tested, they most likely will work with newer versions as well.
