PyGame has the pygame.event and pygame.joystick modules to process inputs.

Wikipedia has an elaborate artikle about Parsing and its meaning in Computer Languages.

RetroPie is based on Rasbperry Pi OS (Lite), you can install the desktop and then separately install IDLE with

sudo apt install idle

You can then find it in the list of programs in the start menu.

Try running it with full paths to both the python executable and your python script. No need for anything in runcommand.cfg.

One more piece of the puzzle...at the end of my script, if I remove the GPIO.cleanup(), then the light stays on.

But, in subsequent calls to my script, I receive a warning that the channel is already in use. It doesn't stop the code, but the programmer in me doesn't like warnings.

My question now is why does the cleanup function change the output of the GPIO pins?

After my genius idea to delete all stuff in this discussion, which only cause trouble and chaos, I figured out to do another attempt and post again. This is version 2 of the little app. The gui and commandline are streamlined into one app. The commandline options are flexible now and it supports a configuration file. Unfortunately in GUI mode only one patch file at a time is supported (but I think this is not a real issue and is a limitation in GUI only). And it can create output folders too. Updated the first post with all relevant information.

It started out so simple.

So with 4.4, most core and main packages installed, but there were a few that wouldn't. lr-stella, lr-pcsx-rearmed failed to build.

So in short - trying this is a mixed bag. Some things will build. Some things won't.
At least the raspberry pi image is a stable platform, but doing PC builds will always be a forever-forward moving target

Thanks. As soon as I posted here, I found this topic and with a bit of modification I was able to get it working. :)

@mitu no problem, I’m working around it with the other emulator for now. I’ve not tested what it’s like but I’m sure I can hold on! Thanks!

@WesleyBidsnipes said in I'd like the Retropie to power on our Xbox and switch to its OneGuide app:

@mitu It's been years since I've messed with udev... does that work with Bluetooth as well? We have one of the Playstation 3 wireless controllers, I think it's the Sixaxis.

It should work.

@corminos said in Setting ServoStik using python and GPIO pins:

I see my problem now. When I first read the instructions on the link, I did not understand what he meant by "switching to hardware mode". At the time I did not have the joysticks and did not understand what that meant. Now I do.

I'm going to do some more reading and then give it a try. Just a little nervous because this is a one-way ticket and I really don't feel like shelling out more for another control board if I screw it up.

Thanks to those who read and responded. I love how active this forum is.

Hey there. I'm just wondering if you had any luck with controlling a ServoStik with GPIO? Did you convert the board to hardware mode and have success?

Thanks.

@mitu Ah, that scuppers those plans then. I think I'll give this up as a failed experiment. I did manage to get Kodi to launch from my green button by importing psutil and check_output and changing the code to

espid = int(check_output(["pidof","-s","emulationstation"])) es = psutil.Process(espid) es.suspend() Kodi = subprocess.Popen("/home/pi/RetroPie/roms/ports/Kodi.sh") Kodi.wait es.resume()

But then the script would no longer start from my crontab on boot so not really usable.

Mystic Mine is a Python game included in RetroPie. You can find it in the Experimental packages. I strongly recommend you to study how this game is programmed as it runs very well on the Raspberry Pi.

The scriptmodule that installs and configures this game in RetroPie is here: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/ports/mysticmine.sh

This looks grate and just what I need. Do you have a complete idiots guide on how to setup on raspberry pi? I have two ultrastik 360s and two dragon rise joystick buttons i want to combine one ultrastik with one dragon rise for player 1 and the the other two for player 2. I've lost count of how many methods I've found and tried but can't get anything working... Been at it for weeks now. Any help greatly appreciated.

I am a complete noob so a step by step guide is really needed thanks

@sdabbs
I don't know sorry. Try using pip to check and upgrade py modules.

pip list pip upgrade xxx.xxx

I fixed it after writing it all out above I figured it out.

First off I needed to run the below and reboot as it turns out not all functions where doing there job:

sudo apt-get install build-essential python-dev python-smbus python-pip python-imaging python-numpy git

Then when you restart the error goes away.

Also the site has the GPIO pins incorrect as it should of been as follows.

Now all works with options and game name displaying will check album art later.
