Multi Switch Shutdown Script!

Well, I'll just turn the volume up, then... ;-)

If the fan is to loud then use following tricks:

You can try to connect to 3,3Voltage (that is PIN 1 on Raspberry GPIO header - I don't recommend this)
Let it connected to 5V and add two Si-diodes to this
like:

+5V --->|---->|------ FAN

each diode consumes 0,6V-0,7V so you've a drop to 3,8-3,6V and the fan is more silent ;) You can also use resistors but this is a bad way I do not recommend.

This might not the right forum to be posting this, but no one else seems to want to help and I don't have enough scripting/programming skills to understand your script.

I have my pi partitioned with PINN (Retropie, OSMC and Raspbian) However your script only works on Retropie. I found another script that does work on both OSMC & Raspbian but doesn't shut down the PI completely. The standby light stays on and the fans keep spinning.

I want to add the shutdown_fan part from your script to this script: LINK

#!/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 sleep 5s & sudo shutdown -h now')

From what I understand I need parts from these parts?:

#From shutdown_fan script 
[ "$1" = "poweroff" ] && raspi-gpio set 4 op pn dl

#From multi_switch.sh scipt
echo "    PowerOnControl GPIO 4 (BCM 4), output, high, power on control!"

        pack_check raspi-gpio
        cli_parameter resetbtn= powerbtn= powerctrl= ledctrl=
        NESPiPlus ${call[@]}

function cli_parameter() {
    unset call
    local PARAMETER=$@
    for i in ${PARAMETER[@]}; do
        value="${CLI#*$i}"
        [[ $value != $PARAMETER ]] && value="${value%% *}" || value="-1"
        [[ $value =~ ^[0-9]{1,2}$ ]] || value="-1"
        call+=("$value")
    done
}

@denisuu Take a look here SHIM ON OFF cut power PART 1
Use this script and set the correct Pins in script. This works

@cyperghost

I tried for more than an hour I really can't get this to work.

In THIS tutorial: Do I copy the content of SHIM ON OFF - PART ONE in part 2.a or 3.a?

I'm also confused with the pin numbers, in the other tutorial he uses pin 5 and in your script it's pin 4 or am I confusing the pin to power down with the button?

cyperghost

@denisuu I don't use OSMC so make sure the directory /lib/systemd/system-shutdown/ is available (I think it is available)

So in your tutorial follow steps till 2b

sudo nano /etc/rc.local
3.1 add above line exit 0 python /home/osmc/shutdown.py &
3.2 or /home/osmc/shutdown.py & alone can also work ;)
setup script according to link from me
4.1 change led_pin from 17 to 14
4.2 poweroff_pin = 4 is okay

No... 5 is physical pin 5 = GPIO 3 so magic are the lines import RPi.GPIO as GPIO ..... GPIO.setmode(GPIO.BOARD) in the python script.

denisuu

Thanks for the help, really appreciate it!!!

It's partially working now, now it goes to sleep and the fans keep spinning like in the original script.
I actually have a Retroflag SUPERpi case (on the other 2 scripts it dind't make a difference).

the power-switch acts a little funny now. Up is reboot and down is sleep.

All steps done: https://pastebin.com/4QcLQY7M

Edit: It's reacts exactly the same on Raspbian.

cyperghost

@denisuu Does the LED blink 3 times? You have to make the gpio shutoff script executable with chmod command. This is essential forget this to mention

Edit it is command
sudo chmod +x /lib/systemd/system-shutdown/gpio-shutoff

denisuu

Yes it blinks 3 times and powers off then after af few seconds turns on again,
or goes to sleep (depending on the possition of the switch).

I did make the script executable I forgot to add it to the pastbin. (added it now)

cyperghost

@denisuu are there any other scripts running? It is a bit hard to guess but you can try to use the original fan_shutdown script. Please install raspi-gpio with sudo apt-get install raspi-gpio

denisuu

Ok I removed the old script on Raspbian and installed yours, it works perfectly now!

Only OSMC left, it's really sad it doens't work on OSMC since that's what I use my pi most often for. OSMC doesn't find the package raspi-gpio or npm. Can I just disable the FAN on that partition? Or get raspi-gpio from somewhere else?

Raspbian:

  296  cd /home/pi/
  297  ls -alF
  298  rm reset.py
  299  rm shutdown.py
  300  rm /lib/systemd/system/shutdown.service
  301  apt install raspi-gpio
  302  mkdir /home/pi/scripts
  303  cd /home/pi/scripts
  304  wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/multi_switch.sh && chmod +x multi_switch.sh                                                                                                         r/multi_switch.sh && chmod +x multi_switch.sh
  305  ls -alF
  306  sudo nano /etc/rc.local     (/home/pi/scripts/multi_switch.sh --nespi+ & before exit 0)
  307  cd /lib/systemd/system-shutdown/ && sudo wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/shutdown_fan && sudo chmod +x shutdown_fan                                                                                                         nt.com/crcerror/ES-generic-shutdown/master/shutdown_fan && sudo chmod +x shutdownfan

@denisuu I think in OSMC it is easily possible to add that function, too. You can try wiringPi instead - I think that should be available. So every call to raspi-gpio must be translated to a wPi call.

EDIT:
I think you should use sudo apt-get install build-essential and then you can further start your build

denisuu

I deleted half of the scipt and it still works, would it be possible to delete everything I don't need from this? That would make it a lot easier to translate it to WiringPi, since I don't understand half of what the script does.

cyperghost

@denisuu You can delete 95% if the script and it will still work. Instead of the raspi-gpio try to translate to wpi calls. Did you try to compile raspi-gpio? https://github.com/RPi-Distro/raspi-gpio

denisuu

@cyperghost I'll try that though I'm pretty new to Linux so that would be a first time compiling anything, good way to learn!

This the most I could delete without breaking functionality. Is it difficult to add the reset button to just reboot?

Retroflag_Raspbian-Shutdown.sh

Danke schön!

cyperghost

@denisuu yes that is a stripped down version. Now use the if clause in line 28 and write your reboot command in. You can further strip down this if you want. Take care about the reset value I am not sure what it's default is. 0 or 1 just pretest with echo command.

denisuu

I compiled raspi-gpio on OSMC and the script is working now!!! I wouldn't know how to further strip this down, it's a miracle I even got this far!

The onlything left to do is the reboot button.

When it's finished is it ok if I put them on Github? All credits to you ofcourse!

denisuu

It was just as simple as putting sudo reboot on the line you said! It seems the button doesn't work every time, sometimes I have to press twice but good enough! Maybe it's just the case...

I put this here:
https://github.com/Denisuu/OSMC_NesPi-SuperPi_Safe-Shutdown

I haven't linked it anywhere so if you have any objections let me know!

Nice job. This is IMHO the best solution to go

Do as you like. I take a look to your git looks good.

Excuse me for my late reply I was on vacation and the internet connection was terrible bad so there was just room for some phone messaging and email. For goodness SMS worked very good ;)

I am just re-doing a new OSMC installation with Retropie embedded in it so I thought I would get a retroflag and finally put it in a case!

@denisuu
I followed your instructions on your git page. I have a question on step 1) You said I could run the command for OSMC as a one liner, but I got permission denied, I just had to run it as sudo in pieces; that worked until i got to the last command "make install". I get the following message:

osmc:/usr/src/raspi-gpio$ make install
gcc -DPACKAGE_NAME=\"raspi-gpio\" -DPACKAGE_TARNAME=\"raspi-gpio\" -DPACKAGE_VERSION=\"0.2\" -DPACKAGE_STRING=\"raspi-gpio\ 0.2\" -DPACKAGE_BUGREPORT=\"serge@raspberrypi.org\" -DPACKAGE_URL=\"\" -DPACKAGE=\"raspi-gpio\" -DVERSION=\"0.2\" -I.     -g -O2 -MT raspi-gpio.o -MD -MP -MF .deps/raspi-gpio.Tpo -c -o raspi-gpio.o raspi-gpio.c
/bin/bash: gcc: command not found
Makefile:361: recipe for target 'raspi-gpio.o' failed
make: *** [raspi-gpio.o] Error 127

Am I missing something?

denisuu

I'm not sure, I tried it a couple of days ago and it was working.

Maybe you can try and compile it from here? https://github.com/RPi-Distro/raspi-gpio
