About the RetroFlag cases! Surprise surprise.... They can cut off power!



  • Main Thread about the Multi Switch Shutdown script

    There are several topics about these cases! And nobody can't tell me what is the behaviour of this cases! They are looking really nice and they are able to ...hold on... COMPLETLY CUT OFF POWER The red LED on the Raspberry isn't glowing after powerdown, so this indicates a real current cut-off. If I'm wrong then please correct me.

    I've written a little instruction to how to install the safe shutdown feature

    NESPi+, SuperPi and MegaPi Instructions!

    This case rocks! It really can totally shutoff power! But we need to edit some service files!
    First: install raspi-gpio with sudo apt install raspi-gpio
    Second: install shutdown_fan script as descriped in point 6
    Today (03/05/18) I got a NESPi+ case so I was able to elaborate the issue. Thanks to @gollumer for your patince!

    1. Set NESPi+, SuperPi or MegaPi case switch to safe shutdown ON
    2. Login with SSH
    3. Type in commands mkdir /home/pi/RetroPie/scripts && cd /home/pi/RetroPie/scripts
    4. DL: wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/multi_switch.sh && chmod +x multi_switch.sh
      3.1 If there is an older version please remove this one with rm multi_switch.sh
      3.2 Otherwise the current downloaded version will get a .sh.1 filename!
    5. Now edit ES autostart with nano /opt/retropie/configs/all/autostart.sh and add script to like ....
    6. /home/pi/RetroPie/scripts/multi_switch.sh --nespi+ & but BEFORE the last line emulationstatio #auto
    7. Install fan_shutdown script: cd /lib/systemd/system-shutdown/ && sudo wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/shutdown_fan && sudo chmod +x shutdown_fan
      6.1 The shutdown_fan is setted to GPIO4 as standard
      6.2 Therefore you might edit with sudo nano /lib/systemd/system-shutdown/shutdown_fan
    8. Write some feedback and sorry for inconvience


  • What inconvenience? This is excellent! Thanks!



  • Sorry for what seem like a stupid question, but does it save metadata? Also I already have installed RetroFlag's "safe shutdown" from their github, do I need to remove that before installing this? Thanks



  • How would I modify it to shut down my fan of it is on GPIO pin 17?



  • @matchaman said in About the NESPi+ case! Surprise surprise.... It can cut off power!:

    What inconvenience? This is excellent! Thanks!

    No problem, @gollumer was my testing site - so thank him for his patience. It is nearly impossible to write working scripts without having the device here for testing... so I decided to buy one and voila, just a quick shot.

    @iLackIQ No not at all. If you are happy with the python way you can of course use that. But it won't provide "safe shutdown" but I also wrote a working python script (based on the retroflags one) that provides safe shutdowns, too. So you decide.

    @cloudlink GPIO17=GPIO17 and Pin17 is Pin17. So you are talking about the 3,3V Pin and mean the pyhsical pin 17 on the header. With a total cut off power this pin looses voltage and your fan is powered down. So the script name in point 6 is a bit misleading I agree. It should named gpio-poweroff, but it doesn't change the behaviour.



  • What I'm asking is, I have a raspberry pi 3 B+ and a NESPi + case. I wanted to know if I can use this for a safe and complete shutfown? And can I use this as a standalone or do I need to have the retroflag scripts installed as well? Finally is there a way to make the reset button restart emulation station or just exit the current running game, instead of restarting the entire system? Thanks



  • @ilackiq Yes safe shutdown is possible.
    With the bash script posted here ... you have all the features you mentioned. Power on power off, reset ends running emulators, reset inside emulationstation restarts emulationstation only (NO REBOOT!). All with safe shutdown!
    But then you have to disable uninstall your python script!

    But you can also use the modified python script that I already posted to you, there you need just to follow instructions and do not need to disable the python script, you exchange it with the one I gave you link. This provides also safe shutdown of course. With this script you just restart emulationstation with reset button... feel free to extend this, if you want - that's also easily possible.



  • Cyperghost this is just superb. I have registered now to thank you for this. I'll be installing it on my setup shortly. Again. Thank you.



  • Hmm didn't work for me, Stretch install, pi 4.4, NesPi+ case and Pi 3B+. Installed script, powered off moved switch to On, booted up and led is now off, reset button doesn't do anything, not tried power button yet, time to snoop on my system.



  • @lininjim Well, did you start the script via autostart or made it executable?
    Is raspi-gpio installed? It is working, believe me ;) If the LED is off, then the script is not active!

    I think I will write an installer script.

    Welcome on board!



  • @cyperghost said in About the NESPi+ case! Surprise surprise.... It can cut off power!:

    /home/pi/RetroPie/scripts/multi_switch.sh --nespi+ &

    Thank you mate, I had not even looked at your script, just installed it etc, when I did I noticed this - # NESPIplus! Install raspi-gpio via "sudo apt install raspi-gpio", no sudo needed, reset, poweroff
    So hang my head in shame haha, installed it, re-ran the script and BINGO. You are a superstar sir. Many thanks. I love it.



  • I am so close to having this working but I am missing something that to you guys is probably glaringly obvious.

    First: install raspi-gpio with sudo apt install raspi-gpio (done, all seemed fine there)

    Second: install shutdown_fan script as descriped in point 6 (again I think thats ok)
    Today (03/05/18) I got a NESPi+ case so I was able to elaborate the issue. Thanks to @gollumer for your patince!

    Set NESPi+ case switch to safe shutdown ON. (done)
    Login with SSH
    Type in commands mkdir /home/pi/RetroPie/scripts && cd /home/pi/RetroPie/scripts (again seemed to go ok)

    This is where I think I have drifted off target.

    DL: wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/multi_switch.sh && chmod +x multi_switch.sh ( i thought I did it right, but not sure now)

    3.1 If there is an older version please remove this one with rm multi_switch.sh (there is definitely a multi_switch file there somewhere, but I cant see it. But if i run with the above dl again its gets renamed to .1/.2 etc. So its there. But if i ssh in and go to the scripts directory I cant see anything there.)
    3.2 Otherwise the current downloaded version will get a .sh.1 filename! (Yep, thats happening alright)

    Now edit ES autostart with nano /opt/retropie/configs/all/autostart.sh and add script to like .... (Not a 100 percent sure what you meant there, did you mean to say look like?)
    Anyway, after edit my autostart looks exactly like this now

    /home/pi/RetroPie/scripts/multi_switch.sh --nespi+ &
    emulationstatio #auto

    (In theory, could I have stopped now, if it had gone right for me, and come back to do the fan aspect later? I only ask out of interest, trying go learn on the fly here)

    Install fan_shutdown script: cd /lib/systemd/system-shutdown/ && sudo wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/shutdown_fan && sudo chmod +x shutdown_fan
    6.1 The shutdown_fan is setted to GPIO4 as standard
    6.2 Therefore you might edit with sudo nano /lib/systemd/system-shutdown/shutdown_fan (again, if I had stayed with the way the nespi+ default setup, would I even need to to this bit?)

    i think my whole issue is the 'not being able to see/access the script file. Something the pi is sharing with me as it cant see it either. The fact that the download adds another version kind of suggests that the original file is there. During my failed attempts to work things out I have seen it deny access to those renamed download files (.2 and .3 before realising I was chasing my tail)

    I really like the idea of having things set up as you have done them. But I am stuck now. After hours of trying I am at the point where I either asked for help, or just gave up and installed the default 'nespi+' script.

    I did read in a follow up, that the question of automatic or executable came into play. Thats a definite level above my capabilities at this moment as I jave no idea which it should be, or how to even change it if its wrong.

    Sorry for asking, but I am totally stuck now and my fumbling around is liable to do more damage than good.



  • @diablo No problem.... Maybe I should provide an installer later. That makes these things automatic.

    Good: raspi-gpio is needed

    What do you mean with: "there is definitely a multi_switch file there somewhere, but I cant see it". Do you use WINSCP and it's command interface? If yes you should press the reload button, and then the files will appear. But all in all prefer the use of putty or kitty. But step by step

    If you type in: mkdir /home/pi/RetroPie/scripts && cd /home/pi/RetroPie/scripts are folders created and are you in this folder with command prompt?

    Now next: if you type in wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/multi_switch.sh && chmod +x multi_switch.sh after that you can use ls command to list the directory. There the file should appear.

    Yes... the autostart is also correct. So it should be a proper setup.

    The GPIO bit to shutoff the fan in the second script needs no change by default! It's just a hint if someone want to rewire the NESPi enclosure.

    What is the output of: ls /home/pi/RetroPie/scripts
    Or can you even execute the multi_switch.sh itself?
    So what is the output of: /home/pi/RetroPie/scripts/multi_switch.sh

    To make something executable means to use chmod +x command. The script is simple a text file and needs to be made excutable, so it can be called by the command line. But you will see it if you execute the script via command line. That's it :)

    BTW: Are other scripts running? Maybe the original from retroflag? You should disable them by removing the call from rc.local therefore sudo nano /etc/rc.localand remove the sudo python ..... entry or set a # before to comment it out.



  • Is there a line I can put into a shell script that will restart EmulationStation, saving metadata?



  • @cyperghost am not at home as I write this so not in range of my gear. But I wanted to say thank you for the response asap. I will get into it later. All looks logical and easy to follow (at this stage thats needed). A couple of things i can confirm are that I am using putty, and I didnt install any retroflag stuff. the directories are there. Its just the multiswitch that seemed to be awol. Again thanks, will check it out asap.



  • @cloudlink yes multi_switch.sh --es-restart
    Therefore I wrote the script...
    For more help type multi_switch.sh --help

    @diablo You are welcome



  • cyperghost, you are a legend. When I first asked the question I had a few doubts about how I had done things. Something had happened with mine that kicked it off track though. I should have added that I am using a pi 3b. Anyway, following your instructions (to the letter), showed that the file structure was correct, though no multiswitch file (sorry for spelling it wrong, but i need to write this fast as i am needed elsewhere in twenty mins). Running the wget https bit gave me a newly created multiswitch.1 file. So it was definitely saving it.

    Ls of the scripts folder still showed nothing there.

    Backtracking through the hierarchy though I discovered both multiswitch and its newly created ms.1 version were both in the 'home' folder. Not where they should have been obviously.

    A quick google on how to move a file within putty (told you i was new to all this) and i moved ms to the scripts folder.

    Ls confirmed the move was good.

    Rechecked the ES autostart details, all looked good.

    Restarted the pi, finally seeing a flicker from the led then eventually lit solid.with ES fully loaded. Tried a game, pressed reset and it jumped back to game selection. Hit the power button and a second or three later it shut down. A number of test shutdowns and resets later and Basically, its working perfectly now (albeit without a fan as the one I had fitted sounds like a 747 taking off, so no idea about fan script working or not, though I have no reason to think it wont now the rest is ok.

    So again, cyperghost, thank you. Your 'fault finding' was used, albeit in a different manner, but its now working as intended thanks to your input. Greatly appreciated.

    I know a lot of people think the nespi has been done to death, but with the + sat next to my c64 and snes minis, and knowing its abilities, the pi is awesome to me now. It just looks'right'.



  • @cyperghost said in About the NESPi+ case! Surprise surprise.... It can cut off power!:

    multi_switch.sh --es-restart

    It worked!
    Thank you so much!

    cyperhost, I tried following your directions for replacing the stock RetroFlag script with your python script (as I had already installed the stock one), but it's not working for me, the red light just blinks indefinitely and never turns off. What did I do wrong? How can I disable or uninstall the python script so I can switch you your bash script and use that instead, since the reset button seems so much more useful on your bash script?

    Thanks.



  • @OhOhOne
    Did you installed the original script by retroflag?
    Can you check if multi_switch.sh is executable and is located into cd /opt/RetroFlag folder?
    Is the python script exchanged by the one given in the thread?

    If you decide to install the bash script then you have to remove the installed python script first. Type sudo nano /etc/rc.local and remove or comment with # the line with the python code.

    Btw: You can easily extend the python with an el-if branch to just restart emulators if they are running.... I just give an example how script can be invoked into other languages. So the bash and the python script function equally.
