Exit emulator with one button press vía gpio

[paradadf]

I would rather ask @supernature2k, as he told me he was creating his own script to do that.

[8bit_astronaut]

Thank you! A lot of people would use it

@supernature2k I SUMMON YOU !!!

[supernature2k]

@Substring Yep, how can I help?

[Substring]

@supernature2k where is your fringing script to kill emulators via GPIO ?

[supernature2k]

@Substring try this:

import RPi.GPIO as GPIO
import time
import os
import thread
import datetime
import socket
import sys
from datetime import datetime
from configgen import recalboxFiles
# this last one retrieves emulators bin names

IPADDR = "127.0.0.1"
PORTNUM = 55355
# IP and port for retroarch network commands

QUIT = 3


GPIO.setwarnings(False)		# no warnings
GPIO.setmode(GPIO.BCM)		# set up BCM GPIO numbering 
 
GPIO.setup(QUIT, GPIO.IN, pull_up_down=GPIO.PUD_UP)
# GPIO on pin 3 is the GPIO 2 in BCM mode
#to Reset+

  
# Define a threaded callback function to run in another thread when events are detected  
def button_pressed(channel):
	
	nwcommand="QUIT"
	retroarch(nwcommand)
	killthats**t(channel)
		
	
#	on quit press, trying to kill all listed emus 
def killthats**t(channel):
	if channel == QUIT:
		for bin in recalboxFiles.recalboxBins:
				print bin
				proc = os.path.basename(bin)
				print proc
				os.system("killall -9 "+proc)


# 	sending network command to retroarch (only exit and reset atm)		
def retroarch(nwcommand):
	try:
		s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
	except socket.error:
		print 'Failed to create socket'
		sys.exit()
	s.sendto(nwcommand, (IPADDR, PORTNUM))
		

GPIO.add_event_detect(QUIT, GPIO.BOTH, callback=button_pressed, bouncetime=2)
while True:
	time.sleep(0.2)

@supernature2k
Does this automaticly start ES again after killing the Emulator?

[supernature2k]

@sevenx no as ES is not killed when you launch an emu

[sevenx]

@supernature2k
Do you have some time, to talk about a new project from me? Over PM?

[supernature2k]

@sevenx ok

[lackyluuk]

@8bit_astronaut maybe this article I wrote some time ago can help. I use the script to reset the emulator. But with replacing the RESET with QUIT you should be able to quit it and return to ES.

[8bit_astronaut]

@lackyluuk that looks great! Ill check it in a moment, thank you so much!

[8bit_astronaut]

@lackyluuk its necesary to have an internet conection for recalbox???

[lackyluuk]

@8bit_astronaut No, I think it should also work without. But it is highly recommended

[DjLeChuck]

@8bit_astronaut Not at all. The internet connection is only useful for scraping directly with your recalbox or for accessing you share folder through your network.

[sevenx]

maybe?

@sevenx Haha nice! I update the wiki page and links.

[DjLeChuck]

Wiki updated! https://github.com/recalbox/recalbox-os/wiki/Enable-Gpio-button-to-close-emulator-with-only-one-button-press

[supernature2k]

I think my script is betta (btw, I corrected this RESET instead of QUIT):

• sending network command to retroarch is better
• using sub's list of emulator bins is better (no need to modify script if new emus implemented)

[DjLeChuck]

@supernature2k Can you update the wiki this way?
