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

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.

@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.

@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)

O.M.A.A

@cyperghost just copied it and paste it ;D

mitu

Can you take a picture of how the buttons are wired ?

cyperghost

@O-M-A-A How do you start the script? How do you start the shutdown.py script?

@cyperghost @mitu
sry for the delay, I was having some error when replaying to u guys.

I actually found a command, when I just executed it, it made the shutdown.py script and power button works immediately.

this is the command:
