Rerns OSMC GPIO button service (customized for NESPi Case and OSMC by seamonkey420)

script.install

#1. Install RPi.GPIO. Open up Putty and run these commands:
sudo su
apt-get update
apt-get install python-pip python-dev gcc
apt-get install python-setuptools
pip install rpi.gpio

#1a. Enable root to make things easier, you can disable afterwards, type and then enter a root password:
sudo passwd

#2. In Putty, create a python script for push button shutdown:
nano /home/osmc/shutdown.py

#2a. Add to the file the following (copy all up until #2b). Once done hold CTRL+X to save, Y and enter:

#!/usr/bin/python
import RPi.GPIO as GPIO
import os

# hide warning
GPIO.setwarnings(0)

# connect RPi numbered pin
button = 5

# hide warning
GPIO.setwarnings(0)

# pins setup
GPIO.setmode(GPIO.BOARD)
GPIO.setup(button, GPIO.IN, pull_up_down=GPIO.PUD_UP)

# wait for button press
print('Wait for button press...')
GPIO.wait_for_edge(button, GPIO.FALLING)

# activate system command
# Updated to make true safe shutdown w/emustation (incase OSMC has been added)
os.system('sudo killall emulationstation & sleep 5s & sudo shutdown -h now')

#2b. In putty, type this command to change permission:
chmod +x /home/osmc/shutdown.py

#3. In putty, type this command to create a systemd service file:
nano /lib/systemd/system/shutdown.service

#3a. Now add to the service file the below. Once done hold CTRL+X to save, Y and enter:
[Unit]
Description = GPIO shutdown button
[Service]
Type = idle
ExecStart = /home/osmc/shutdown.py
[Install]
WantedBy = multi-user.target

#4. In putty, type this command to enable auto startup:
systemctl enable shutdown


#Connect a push button to RPi GPIO pin #56
#Start the service without reboot:
systemctl start shutdown

#5a FINALLY, to enable the power on LED, we need to add a line to the /boot/config.txt file to enable the serial port
#This case uses the UART port for the led.
sudo nano /boot/config.txt

#5b, add this line of text to the end of config.txt and then CTRL+X and Y and enter:
enable_uart=1


##Press the power button to shutdown OSMC safely!
##Be sure you have toggled the safe mode switch on the pcb to ON
##Once you start up your Pi the LED will also be enabled! updated on 5/6/18

#------------------------------------------------

#You can make the reset button reboot OSMC by doing the following (basically same steps as above but different names and button):

#1. Create a python script for push button shutdown:
nano /home/osmc/reset.py

#2a. Add to the file. Once done hold CTRL+X to save, Y and enter:
#!/usr/bin/python
import RPi.GPIO as GPIO
import os

# hide warning
GPIO.setwarnings(0)

# connect RPi numbered pin
button = 3

# hide warning
GPIO.setwarnings(0)

# pins setup
GPIO.setmode(GPIO.BOARD)
GPIO.setup(button, GPIO.IN, pull_up_down=GPIO.PUD_UP)

# wait for button press
print('Wait for button press...')
GPIO.wait_for_edge(button, GPIO.FALLING)

# activate system command
# reboots OSMC
os.system('sudo reboot')

#2b. Change permission:
chmod +x /home/osmc/reset.py

#3. Create a systemd service file:
nano /lib/systemd/system/resetbutton.service

#3a. Add to the service file. Once done hold CTRL+X to save, Y and enter:
[Unit]
Description = GPIO reset button
[Service]
Type = idle
ExecStart = /home/osmc/reset.py
[Install]
WantedBy = multi-user.target

#4. Enable auto startup:
systemctl enable resetbutton


#Connect a push button to RPi GPIO pin #56
#Start the service without reboot:
systemctl start resetbutton
