I finally got around implementing a shutdown button. It is based on the
script gib8 created but I modified it slightly. The hardware is a bit
different too. I use a delayed button; you have to press and hold it for
about 2 seconds before it kicks in.
The hardware consists of just a few components:
15653
1565215651
As mentioned, I slightly modified gib8s script and called it
*csos-shutdown*. It is located in */usr/sbin* and contains the
following:
Code:
--------------------
#!/bin/bash
sudo echo in > /sys/class/gpio/gpio91/direction
sudo echo out > /sys/class/gpio/gpio200/direction
sudo echo 1 > /sys/class/gpio/gpio200/value
while [ true ]; do
i=`cat /sys/class/gpio/gpio91/value`
if [ $i -eq 1 ]
then
sudo echo 0 > /sys/class/gpio/gpio200/value
sleep 0.5
sudo echo 1 > /sys/class/gpio/gpio200/value
sleep 0.5
sudo echo 0 > /sys/class/gpio/gpio200/value
sleep 0.5
sudo echo 1 > /sys/class/gpio/gpio200/value
sleep 0.5
sudo echo 0 > /sys/class/gpio/gpio200/value
sleep 0.5
sudo echo 1 > /sys/class/gpio/gpio200/value
sleep 0.5
sudo echo 0 > /sys/class/gpio/gpio200/value
sudo shutdown -h now
break
fi
sleep 1
done
--------------------
This script needs to be executable, so run the command *chmod 777
csos-shutdown*
Next, create a service file called *shutdown.service* located in *
/etc/systemd/system*
The shutdown.service file contains the following:
Code:
--------------------
[Unit]
Description=Shutdown Switch
[Service]
ExecStart=/usr/sbin/csos-shutdown
Type=idle
[Install]
WantedBy=multi-user.target
--------------------
Then enable the service: *systemctl enable shutdown.service* and reboot
the system.
How does it work: press and hold the button (about two seconds) until
the LED starts to blink. Allow about 30 seconds (to be sure) to let the
WB shutdown safely before removing the power.
