@mitu Excellent thank you!

@lolonois Thankyou very much. I will keep this in mind !

@mitu
When I tried using gpionext I kept being met with error messages. I ended up just getting a few different parts to work with the super pi girl drivers. Still, thank you for the help.

Thanks for your help. Between the documentation and the example, I have the button matrix somewhat working I think.

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?

Take a look at https://github.com/recalbox/mk_arcade_joystick_rpi, it's similar to what you have in mind and it's already included in RetroPie.

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

Appreciated, thank you.

I've merged those 2 PRs and tagged other users that might be interested Pi 4 compatibility/support.

@fraggle200 said in Cabinet Control Panel not detected on new clean image, via Pi2Jamma.:

@mitu I installed Uinput by following a few links for the install but this method ultimately got me installed, just as a precaution it wasn't already there. https://www.raspberrypi.org/forums/viewtopic.php?t=221622

That's not needed, since PikeyD doesn't look like it uses python. There's - similarly - a Linux kernel module named uinput, that I think it's used, but it's loaded by default on a RetroPIe image (you can check /etc/modules).

It seems you do need to install something - see the manual:

Once connected and booted up, you can navigate to the terminal to install the required
gpio drivers.
In RetroPie, you can do this by pressing the Ctrl-Alt and F4 key; this changes view to a
virtual terminal window, which you can run ‘emulationstation’ to go back to
RetroPie.
...

It looks like you need to install GPIONext, a GPIO user driver to make the gamepad(s) work.

It's not python code but.. maybe could be useful for you.

While ago - Using gpio and PWM - I did add some flash effects to every buttons on my bartop build.

and you can find source code here.

FYI My friend 'sana2dang' made original code for me and I just add little bit.
Although I am not using this any more and moved to RGB effect using Aruino :) but worth trying

@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.
