@John_RM_70 Try one command at a time and see which ones locks up the Pi. It's probably tvservice, but it could be because of the previous command, which specifies might specify an invalid mode. Have you tried tvservice -p (preferred mode) ?

@mitu said in Modify Power Button Behaviour to 'Hold for three seconds'??: You can increase the bouncetime from 2sec to something larger. Even as it is now, just a single quick push will shut the software down - i dont have to hold the button at all. Perhaps I need to use a different script that relies on the button being held.

@JToivonen got what you mean and here is the "un modified" solution...simply if you're playing plug the usb controller and when you finish just unplug it and it will shutdown automatically!, even when a power trigger happens "electricity went off then come back again" and found that your gamepad isn't connected it will shut down :) here is the python file you just need to edit the line that kills qjoypad to kill whole system add poweroff or shutdown -h as you use in your momentry switch don't forget to make the file run at start and special thanks to pablo idea behind the script is that system creates a js0 file for controller 1 inputs and js1 for controller 2 when connected and so on, the script searches for that file if it's found that mean you've connected the gamepad and probably playing a game and when you finish unplugging the gamepad removes js0 file and when the script discovers the file is not found it kills an app process called qjoypad which you'll change to shutdown please note you're not gonna use //User Variables section in this code so just ignore it.

Ok I see... So it's possible to use my script and retropie However, only on a computer. Thanks for the information I wasn't aware that on RP almost all emulators don't run on X. Thanks a lot :)

@mesym Well I don't know what's wrong but this worked for me. It starts Tetris and shows me pointer adress. Something wrong with your py-fu? import os import time import subprocess p = subprocess.Popen(['/opt/retropie/supplementary/runcommand/runcommand.sh','0', '_SYS_', 'gb', '/home/pi/RetroPie/roms/gb/Tetris (JUE) (V1.0) [!].gb']) while 1: print(p) time.sleep(5)

@mitu I did it, but then suddenly my wi-fi dongle stopped working. Then I tried some more troubleshooting attempts for that and messed stuff up even more. Much as it pains me, I'm just reinstalling RetroPie and doing it all from scratch. I made backups of everything, so hopefully I'll be able to salvage some of my customizations.

i'm afraid I cant find much on how to output to this from python. Im no coder, it needs to be call-able from python once Ive done with my process. thanks for info!.. do you have any more? Other options please! what other options do I have to get my character input into ES and retroarch please?

I'm having the error 404 today, but other things in github still ok. edit: Typing wrong was what got me into that, now it's alright

so my remote monitering script helped rule out overheating on my pie its become unstable suddenly... so time to backup and reflash

Thanks! I'll give that guide a go, and see what turns up.

@mitu I gave it another shot and moving the line to autostart did the trick! Music still starts and I get to keep the music folder on my usb stick. Thanks!

Thank you for the point to minty pi. Will post the first images as soon as it‘ in „beta“. But it will be fairly easy to print and build ;) will be in beta somewhere in q1 :D

@nemecyys said in runcommand-onstart.sh pass data to python script: Because im running this python script every time i run onstart.sh or onend.sh does that mean there will be LOTS of instances of it running? On normal typical usage, no. The runcommand script calls the onstart one and waits it finish. The way you're invoking your python script in onstart also makes it wait the python script to finish. Then, from what I'm seeing from the codes, I believe that there won't be lots of instances running. With a Bash Script: Would this also be the case? Would i want to exit the bash after running and achieving the desired result? There's no need. *also, any links to some of meleu's coding goodness? You can find links to some of my scripts on the "useful topics" post (link on my signature). You can find many other useful info there. ;-) Oh, as @cyperghost said, we usually use this thread to talk about shell scripting. By the way, you asked above and I'm not sure if you got an answer: the /dev/shm/runcommand.log file is deleted after a shutdown/reboot.

@buzz Sorry for the long delay - I was prevented from working on this. When I did get around to it though, I was able to use this advice to come up with a solution. Thanks a bunch!

I have reinstaled retropie , and Reicast is ok now. but now I have another issue,I can't see my Pi in my network -_-' . BTW , you can close this topic.

@anasazi29 Broadly speaking, here is what you need to do: You need a python script that will watch a GPIO pin (that you have wired to a normally open switch like an arcade button--other wire to ground) such that when the button is pressed, the script sends a keypress. The key you send (suggestion: "ESC") would have to be picked up by the emulator as EXIT. So, you will have to go into your retroarch.cfg file, disable the hotkey function, and set the EXIT function to "ESC". I know of a few ways this has been done in the past. One of the more popular is to use the adafruit Retrogame software. This basically takes care of the scripting process and leaves it up to you to configure what keys the GPIO pins trigger. Some folks use ONLY this solution for input control. I also like mholgatem's GPIOneer which does the same thing, but uses a more elegant interactive configuration, then a web interface once it is setup. It is also easy to configure combo keys and to send full commands (I use it to send commands to increase and decrease master volume).
