{SOLVED} How to make a momentary push button that exit games and take me back to game menu ?

O.M.A.A

Hi guys,
I have been trying to build my ultimate ps classic using raspberry pi 3b+, the reset button, and power button all works fine, but I had difficulties in making the open button(that exit games and takes me directly to the games menu) works with many attempts.
@mitu guided me to script created by @cyperghost (https://github.com/crcerror/ES-generic-shutdown), but I didn't understand a thing xD.
so, is there an easy explanation for how to make that script to work ?
Thanks ;)

What exactly doesn't work and why do you think you need to understand the script ? Read again my reply - you just need to map the button action to execute the script with the --es-closeemu option. You don't need to use the script itself to interpret the buttons press, for that you can use the same method you used for the other buttons.
How did you configure the power and reset buttons - did you use a script ?

@mitu
I just watched ETA Prime videos on how to setup shutdown and reset button, so basically, just copying what he did.

I tried the scripts that both of u did, and a file name: multi_switch.sh was installed, I opened it with notepad++, searching for the --es-closeemu, but no idea where can I map my gpio which is in my case GPIO 7 (pins 25 and 26).

mitu

@O-M-A-A I'm not familiar with those videos, so I can't advise about that. Do you have a link to the script you used for the power and reset button actions ?

@mitu
thanks for ur reply,
here is for the shutdown button:

#!/usr/bin/python
import RPi.GPIO as GPIO
import time
import subprocess

GPIO.setmode(GPIO.BOARD)

# we will use the pin numbering to match the pins on the Pi, instead of the
# GPIO pin outs (makes it easier to keep track of things)
# use the same pin that is used for the reset button (one button to rule them all!)
GPIO.setup(5, GPIO.IN)

oldButtonState1 = True

while True:
    #grab the current button state
    buttonState1 = GPIO.input(5)

    # check to see if button has been pushed
    if buttonState1 != oldButtonState1 and buttonState1 == False:
        # shutdown
        subprocess.call("shutdown -h now", shell=True,
          stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        oldButtonState1 = buttonState1

    time.sleep(.5)

O.M.A.A

@mitu
is it possible to just send me a file were it is already mapped and rdy to exit game on gpio 7, so I just need to drop it ?

mitu

@O-M-A-A You'll need to add another test for GPIO7 in the while loop, check if GPIO7 is pressed and then call the multi_switch.sh script to reset the current emulator. You'll need to copy the script to /home/pi/scripts first.

#!/usr/bin/python
import RPi.GPIO as GPIO
import time
import subprocess

GPIO.setmode(GPIO.BOARD)

# we will use the pin numbering to match the pins on the Pi, instead of the
# GPIO pin outs (makes it easier to keep track of things)
# use the same pin that is used for the reset button (one button to rule them all!)
GPIO.setup(5, GPIO.IN)
GPIO.setup(7, GPIO.IN)

oldButtonState1 = True
oldButtonState2 = True

while True:
    #grab the current button state
    buttonState1 = GPIO.input(5)
    buttonState2 = GPIO.input(7)

    # check to see if button has been pushed
    if buttonState1 != oldButtonState1 and buttonState1 == False:
        # shutdown
        subprocess.call("shutdown -h now", shell=True,
          stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        oldButtonState1 = buttonState1
    
    if buttonState2 != oldButtonState2 and buttonState2 == False:
        # Reset emulator
        subprocess.call("/home/pi/scripts/multi_switch.sh --es-closeemu", shell=True,
          stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        oldButtonState2 = buttonState2
  
    time.sleep(.5)

@mitu Yes that's right ... but you can further utilize the script. If you use the parameters --es-pid and --rc-pid you can determine in which state the Raspberry currently is. So is ES ready booted? Is there an emulator currently running.... and then set actions for each state.

@O-M-A-A
You should get in touch with some coding

O.M.A.A

@cyperghost I'm too bad with coding xD but I hope one day I get used to some of it.
@mitu I copied the script u posted to /home/pi/scripts,
so, now I have this script in this destination: /home/pi/scripts, which contains the script u posted, and another script is in this destination: /home/pi/RetroPie/scripts which is called multi_switch.sh and it contains a very long script.

the power on/off button still working, but I didn't understand this part (You'll need to add another test for GPIO7 in the while loop, check if GPIO7 is pressed and then call the multi_switch.sh script to reset the current emulator), which is why still exit emulator button not working yet.

cyperghost

@O-M-A-A Please perform following command
chmod +x /home/pi/scripts/multi_switch.sh to make it executable

mitu

In addition to what @cyperghost said, copy the multi_switch.sh script also in /home/pi/scripts - that's the script I meant to copy there, not the one you posted (and I modified).

O.M.A.A

@mitu @cyperghost
ok I will try it now

O.M.A.A

@mitu @cyperghost

I renamed the file in /home/pi/scripts, to multi_switch.sh as in this picture

and it contains only the script u posted:

then I executed this command : chmod +x /home/pi/scripts/multi_switch.sh

but still didn't work, even the power button doesn't work now.
not sure what's the mistake I'm doing here.

mitu

@O-M-A-A You misunderstood the instructions - maybe I wasn't so clear.
You already have a script - the one your posted. Modify it and add the code I posted. In addition to the new script you have, download and put the multi_switch.sh script, which you can get from https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/multi_switch.sh, into the /home/pi/scripts folder, then make it executable (chmod +x /home/pi/scripts/multi_switch.sh).
Run your original script (now modified) and see if you get the desired behavior.

cyperghost

@O-M-A-A This does not make sense

Please use command wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/multi_switch.sh -O /home/pi/scripts/multi_switch.sh

and then again chmod +x /home/pi/scripts/multi_switch.sh

O.M.A.A

@mitu thank you very much for your response,
I will try it now, and I hope I get it now

O.M.A.A

@cyperghost @mitu

Is this what u guys meant ?

shutdown.py contains the modified script, while I downloaded the multi_switch.sh and drop it this destination, then I executed this command (chmod +x /home/pi/scripts/multi_switch.sh)., the power button is working but not the exit emu button.
I hope this is what u guys meant !!

Not really:

Run your original script (now modified) and see if you get the desired behavior.

You need to run shutdown.py, not the other way around.

O.M.A.A

@mitu
the original script's name is shutdown.py, I did modified it, or what did u mean ?

cyperghost

@O-M-A-A How do you startup this python script? (It should be the one @mitu presented you in this posting)
