Emulator Exit button GPIO

[Substring]

haha i'm the man

Seriously, most of emulators are listed in the recalboxFiles.py. Would need to improve it because all bins are not listed there. But I really like this idea : kill the running emulator, or even reset the game (there is a topic on it somewhere, will gid this and update my post) -> https://forum.recalbox.com/topic/3435/game-reset/6

solution via python with network commands:

import os
import RPi.GPIO as GPIO
import time
import socket
import sys
# addressing information of target
IPADDR = "127.0.0.1"
PORTNUM = 55355
 
# enter the data content of the UDP packet
PACKETDATA = "RESET"
 
# initialize a socket, think of it as a cable
# SOCK_DGRAM specifies that this is UDP
try:
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
except socket.error:
    print 'Failed to create socket'
    sys.exit()
#s.connect((IPADDR, PORTNUM))
 
# connect the socket, think of it as connecting the cable to the address location

data = bytes(PACKETDATA)

GPIO.setmode(GPIO.BCM)
GPIO.setup(3, GPIO.IN, pull_up_down=GPIO.PUD_UP)

def exitEmulator(channel):
	print("exitEmulator")
	print(IPADDR)
	print(PORTNUM)
	print(PACKETDATA)
	s.sendto(PACKETDATA, (IPADDR, PORTNUM))
    
GPIO.add_event_detect(3, GPIO.FALLING, callback=exitEmulator, bouncetime=500)

while True:
    time.sleep(10)

@supernature2k Hi,

I'm replying to this old topic because I'm currently working on a project that needs such a feature. I tried your last script, I just removed GPIO code at for now to test, so here is my code:

import os
import time
import socket
import sys
# addressing information of target
IPADDR = "127.0.0.1"
PORTNUM = 55355

# enter the data content of the UDP packet
PACKETDATA = "RESET"

# initialize a socket, think of it as a cable
# SOCK_DGRAM specifies that this is UDP
try:
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
except socket.error:
    print 'Failed to create socket'
    sys.exit()
#s.connect((IPADDR, PORTNUM))

# connect the socket, think of it as connecting the cable to the address location

data = bytes(PACKETDATA)

print("exitEmulator")
print(IPADDR)
print(PORTNUM)
print(PACKETDATA)
s.sendto(PACKETDATA, (IPADDR, PORTNUM))

So to try it, I start a retroarch game then I launch the script:

# python rpi-exit-emulator.py 
exitEmulator
127.0.0.1
55355
RESET

But in fact it does nothing, I'm still in the game (with no reset). Any idea ?

@oyyodams it's RESET, not exit

[OyyoDams]

@substring yes that's it's supposed to do... but no reset by the way...

[Substring]

@oyyodams check on command line if you can connect to the port some netcat commands should do it

[OyyoDams]

@substring Well I found a great doc on the wiki. But...

• I can't use netcast: nc is not include in this buildroot build (and I can't rebuild by now)
• It seems retroarch doesn't respond to any command. I tried to edit retroarch.cfg to add network_cmd_enable = "true", nothing better (even after reboot)

I will not let go;)

[Substring]

@oyyodams hold the door !!!

[OyyoDams]

@substring

Don't worry I keep up the good work, things begin to be better, news soon

[OyyoDams]

Ok solution:

network_cmd_enable = "true" has to be added in /recalbox/share/system/configs/retroarch/retroarchcustom.cfg

[supernature2k]

@oyyodams sorry I'm late...
Does it work now?

[OyyoDams]

@supernature2k yes, see my post above Thanks a lot for your scripts!
