Multi Switch Shutdown Script!

Lol. Yeah, I originally had the fan connected to the fan connector, but recently changed it due to the noise. You're right: the fan doesn't shut down. I'm not at home right now, but when I get home I'll try the command you suggest (raspi-gpio set 4 op dl) from the terminal and see what happens.

Yes, thank you. I think that's the way the GPIO is intended for.

@cloudlink
About GPIO17, of course both of you can shutoff the fan by uncommenting line 184 in my script and then edit the call in line 311

 NESPiPlus 2 3 4 14

to

 NESPiPlus 2 3 17 14

But I assume GPIO 4 shutoff the fan if installed in case connector!

[gollumer]

Ok, I tried aspi-gpio set 4 op dl from the terminal, and nothing happened (as expected).

I then uncommented line 184, and edited line 311 as shown (replaced 4 with 17). I rebooted, then shutdown using the button. Shutdown is fine, but the fan is still working. So...perhaps I do need to go back to using fan connector.

[cyperghost]

@gollumer Yes I think the fan connector works with GPIO4, so please uncomment the line 184 and set the number back to 4. I think then it's possible to shutoff the fan.

Do you really use GPIO 17 or do you mean PIN 17 (That's a 3.3V Pin) and can't be shutoff! So this does not work at all! I would assume to the old connection provided by the case itself ;) GPIO 4 and the connector on the NESPi+ board ;)

[cloudlink]

Thank you cyperghost.
I connected my fan to the Nespi+ fan pins. I uncommented line 184 in /home/pi/RetroPie/scripts/multi_switch.sh. Now my fan turns on when I power on the system and my fan turns off when I power off the system.
I have the issue though where my fan is way too loud, spinning way too fast. Is it possible to control the power level?

EDIT: Ok, I see...pin 17 on the GPIO board isn't the same as GPIO 17. I'm connected to pin 17.

@cloudlink Okay NESPi+ is 100% supported now, thank you.
About the spinning speed.... Well I would not use resistors because you will likely need some that resists to 1-2Watts. The easiest way imho is to use 1 or 2 simple Si diodes. Each drops the voltage up to 0.7V so you have 4.3V if you use one or 3.6V if you use two diodes. That's a dirty hack but will work - 1N4001 and higher are a good choice.
The cleanest (cheap) way would be a step down regulator. The masters/professional way is a PWM regulator together with NTC/PTC ;)

@gollumer Yes we talk about BCM numbers and physical PINs there are also wPi numbers for complete confusion! But you're right use the common pinout helpers that are free to use ;)

[gollumer]

Ok, I connected the fan back to the FAN connectors, and edited line 311 back to NESPiPlus 2 3 4 14. I tried it first with line 184 still un-commented. It wouldn't shut down, but would instead go into a reboot loop. (Shut down, immediately reboot, part-way through ES loading up, it would shut down again, then reboot...and keep doing that.) I then edited line 184 and commented it out again. It now shuts down, but the fan does not turn off. Only way to turn off the fan is to unplug the power supply.

@gollumer You can update script

1. cd /home/pi/RetroPie/scripts
2. rm multi_shutdown.sh
3. wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/multi_switch.sh && chmod +x multi_switch.sh

I updated to 0.42

Ok, I updated the script. Unfortunately, it now gets stuck in the reboot loop when shutting down. It gets several seconds into the video splash screen, then reboots...keeps doing that over and over until I unplug.

[cyperghost]

@gollumer That's weird becasue @cloudlink reports good results.
Then please comment line 183, then the same version is restored.

This is caused as you leave the LOOP caused by a button press. But don't know why ... can you recheck the ON/OFF position of the switch. Can you shot some photos from you setup?

Then later you can use the raspi-gpio command raspi-gpio set 4 op dl manuell then you immedialty should loose power. And more weird becasue you said you typed the command raspi-gpio command later and nothing happens... But again: weird becasue cloudlink got good results. I can help you to shut off then fan with a workaround but let us eloborate this first.

Mine is working perfectly.
If I have an emulator running and I hit Reset, it only exits the emulator. If I have no emulator running and I hit Reset, it restarts Emulationstation.
If it is off and I press the Power button, it powers on. If it is on and I press the Power button, it safely saves metadata and shuts down.

I have noticed though that if I press and release the Reset button too quickly, it does not work. Is there a configured amount of time it must be held?

[gollumer]

Ok, I've commented line 183. It now shuts down properly again, but the fan still runs.

I turned it back on, exited ES, then typed the raspi-gpio set 4 op dl command. Nothing happened. The fan keeps running.

I've re-checked the on-off switch. It's firmly all the way in the on position.

Here's a photo, if that helps. (For some reason the photo isn't showing up...) Here's the direct link instead: https://www.dropbox.com/s/vgt95faj8oe65ib/raspi3.jpg?dl=0

@gollumer The link you've posted is not working :( So it may be helpfull to upload your photo again ;)

I assume two things as @cloudlink is reporting a good shot and even a powered down fan.

1. There are several cases around with different PCBs (maybe annother reversion)
2. You have annother script running in background

You are talking about an endless reboot loop...
This isn't possible with my script. In the worst case it will powerdown the Raspberry, but won't reboot. Can you post output of ps -la please? This will show all programms running. So you can be sure no other script is running.

Sadly I don't have this case! Without this it's a bit difficult to give you best advices. So it's just a bit of try and error! But I've to thank your for your energy in testing.

Can you type raspi-gpio set 4 op dl if ES is running? And what is happening then?

@cloudlink

I have noticed though that if I press and release the Reset button too quickly, it does not work. Is there a configured amount of time it must be held?

Yes it's the sleep loop. The state of all switches is polled only every second. So it can take up to one second until the button press is detected. It's caused by the script itself you may use sleep 0.5 instead of sleep 1

[gollumer]

Thank you very much for your help, you've been very patient.

I re-sized the image after I posted the link, so I think Dropbox thought it was a new image. Here's a new link: https://www.dropbox.com/s/cevy9c5zeijm434/raspi3.jpg?dl=0

Here's the output from ps -la:

When I run this command (raspi-gpio set 4 op dl) with ES running, nothing happens. I get straight back to the command prompt (running in an SSH session from my laptop). Fan still runs.

I hope this helps.

I'm not sure if this could cause the issue, but I had to correct the path in step 5 of the installation instructions at the top of this thread:
From
/home/pi/RetroPie/multi_switch.sh --nespi+ &
To
/home/pi/RetroPie/scripts/multi_switch.sh --nespi+ &

[cyperghost]

@gollumer Thanks.... Yes it looks all clean.
Annother user posted an image of the case maybe you can compare revision numbers but I see really no error in the setup.... strange strange strange....

Can you please post output of cat /opt/retropie/configs/all/autostart.sh

@cloudlink Oh really? Yes that a wrong path! Indeed. I corrected this! Thank you so much. That may caused the issue at all! And your fan shuts off if you powerdown the system?

[cloudlink]

Sorry I didn't think to mention that earlier. I forgot I had corrected that, but I just remembered while retracing my steps.
See if that fixes the issue.

[cloudlink]

Yes, my fan shuts off when the system shuts down after I uncommented line 184 in /home/pi/RetroPie/scripts/multi_switch.sh

Here you go:

pi@retropie:~ $ cat /opt/retropie/configs/all/autostart.sh
/home/pi/RetroPie/scripts/multi_switch.sh --nespi+ &
emulationstation #auto

[cyperghost]

@gollumer and now... output of ls /home/pi/RetroPie/scripts

I still found no error ;)
