Multi Switch Shutdown Script!

cnoto

@cyperghost I am using your generic script above for a shutdown with a momentary button on a pi3a and Im seeing the following message:

Kernel panic - not syncing attempting to kill init!

Any thoughts why im seeing this?

Many Thanks,

Idelacio

@cyperghost

Oops, sorry for the slow reply.

Yup! That worked perfectly. Thanks! <3

@cyperghost I have used this to shutdown my pi.
But i have come across a few posts saying that it can be used to shutdown a emulator or restart ES.

Can it be used to finishing killing xinit after exiting a game?

cyperghost

@exarkuniv as long as the call is

Runcommand.sh
Xinit
X Application
And all calls are children of the shell parent process then it is very likely that it will work. But never tested before

@cyperghost yes i have the command going through run command to lunch the game

here is my command that i have for my emulator.sh

dhewm3 = "XINIT:/opt/retropie/ports/dhewm3/dhewm3"
default = "dhewm3"

so i know that it calls it correctly. well i think it does

what do i need to do to set the shutdown script up. i have tried to follow your info as best as i could and i still get lost on it.

@exarkuniv there is an issue with dhewm3 that the x window does not close properly after exiting the game. I was going to report it on the github page but never got around to it. It's likely to be a raspberry pi related issue or it could be because we aren't running a full desktop environment. Not sure if the dev would/could help.

There is a setting you can turn on via raspi-config that allows you to kill an x session using cntrl+alt+backspace. That was my workaround when trying to close dhewm3.

@quicksilver thanks for the idea. i managed to get my kill script to work and map my hot keys with Xboxdrv to start it so now my game/ports now exit quickly. but ill remember that if i end up needing it down the road

@cyperghost
Hello and thank you so much for all your hard work in creating the fantastic scripts that you do.

I have built a dual joystick controller with a Raspberry Pi 4 inside.
It is running Retropie 4.7.1
I have a button wired to pins 5 and 6 of the GPIO Header which shorts those pins when the button is pressed.

I would like to use this button as my safe shutdown button.

Please can you tell me whether your script will be good for this and if so should I install using...

wget -O - "https://raw.githubusercontent.com/crcerror/retroflag-picase/master/install.sh" | sudo bash

Many thanks once again for any help.

@vwgolfman You are using the "wrong" script for this. Please visit https://github.com/crcerror/ES-generic-shutdown

There is a dedicated command line option for a single GPIO button. The Retroflag script is just a small subset of the one linked above.

Edit:
Did forget, I wrote small walk-through already here: https://retropie.org.uk/forum/topic/17415/multi-switch-shutdown-script

On resetting games with the reset button I'm getting the following error:
/home/pi/RetroPie/scripts/multi_switch.sh: line 63: kill: (####) - No Such Process

Where #### is the process number.

It also producses the following message on closing the process:
Killed

As it looks messy having persistant messages like these show between screens is there a clean way to hide them?

I don't want to completely prevent error messages showing as sometimes I do screw up so just these ones specifically. If it's all or nothing though I'll just have to accept that.

@cyperghost
Thank you so much, your coding is fantastic and I am now using your safe shutdown script successfully!

Could I please ask, is there a version which monitors the shutdown button continuously rather than polling it every second or so?

cnoto

@cyperghost I just used this script for a generic button on a zero 2 with no luck. Would anything be different about the pi zero 2?

@cyperghost Hi sweet man :v, I wanted to know if you think that by modifying the paths in your install instructions I could make your script work on batocera, since it's emulation station same as retropie, I have a generic button I want to use to save shut down, any help is appreciated

I have got this error on my Raspberry pi 3b+:

DTOVERLAY[error]: failed to open 'RetroFlag_pw_io.dtbo'

Failed to read 'RetroFlag_pw_io.dtbo'

What Can I do?

The file is installed in the correct place, in fact, I installed it with the installer and checked that everything was correct, but the dto does not load it.

@BlackDraGoN-0 That error is not from @cyperghost's script, the script doesn't have any references to that .dtbo file.

My pins are always level=0 fsel=0 func=INPUT how can I change level 1 when I press a button?

@mitu I have done a clean installation of RetroPie, and I have installed the multiswitch, but every time the leds come on and it turns off. I have a Nespicase+ and a Raspberry Pi 3B+. I have also tried with the original retroflag script and the same thing happens.

When I install the script, the nespicase+ always turns off. My Nespicase has a Reset button that is a push button, but the Off button is one of those that stays pressed when pressed, and I have to press it again to get it out.

mitu

@BlackDraGoN-0 I'm not familiar with the case, but I remember you had to activate a switch in order to have the script functional - https://retroflag.com/download/NESPi_CASE+_Manual.pdf mentions this switch and I presume it has to be switched ON (default is OFF).

@mitu I have got the switch in ON.
