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

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

@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 ?

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

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:

Why are you posting an image of a text, instead of posting the text ? It makes it harder to copy it and verify the URL/file. We know now how the script looks like, the issue is why the 2nd button doesn't work - can you show us how you wired the buttons to the PI ?

@mitu I received error when posting it as it marked as a spam, give me seconds

@O-M-A-A The link to the script is not so important now.

the white and grey wires are for the power button, while the brown and red are for the exit emu button

mitu

@O-M-A-A I don't think the brown/red are tied to GPIO 7.

Modify the script and change 2nd buttons's pin number from 7 to 33 and see if you get a different result:

#!/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(33, GPIO.IN)

oldButtonState1 = True
oldButtonState2 = True

while True:
    #grab the current button state
    buttonState1 = GPIO.input(5)
    buttonState2 = GPIO.input(33)

    # 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

@mitu didn't work,
would it be fine if u get access to my computed and try it yourself as maybe the way I'm doing it is wrong.

Can't do that, I'm sorry.

@mitu it is okay thank you for your patient,

I will just summarized what I did so u will have an idea maybe of the mistake I did, when I installed the retropie image, I basically run the link to the script (shudown.py) and this made the power button to work.

Then I open it with notepad++ and I modified it to install the exit emu button.

lastly, I downloaded ur file (multi_switch.sh) and executed the command u provided it me.

for now pins are 3+4 for the exit emu button and 5+6 for the power button.

I edited the post - try putting the reset pins (brown/red) on the original position and change the GPIO number from 3 to 33 (or just copy the edited script).

O.M.A.A

@mitu I put the 2 wires back to the same position and I edited the file from 3 to 33, but didn't work

@O-M-A-A Please remeber to do a restart after every change!

O.M.A.A

@mitu

Yeah, I do that with every change
