Handle gyro from external gamepads

[d0k3]

This plugin really does work like a charm, thanks a lot for your work!

Right now, there's no easy way using gyro input from external gamepads, like, for example Switch Pro Controllers. The Steam Deck software recognizes gyro input and allows to either ignore it or map it to something else (mouse or stick), but there's no easy way to let the gyro input be handled by emulators.

Would it be possible for SteamDeckGyroDSU to also handle these inputs, possibly depending on some conditions? Meaning: if a Bluetooth gamepad is connected, ignore the Steam Decks internal gyro and use the gamepad gyro instead.

List of gamepads with gyro to handle:

• Steam Controller (the easiest to implement for now?)
• Switch Pro
• Switch Joy-Cons
• Dualshock 4
• Dualsense
  ...

Features:

• Manual switching between gyro sources
• Automatic switching when external gamepad connected (+ config for that behavior)

Nice, progress!

I'm not sure if this will help but emudeck does have a guide on enabling Gyro for external controllers
https://emudeck.github.io/emulators/steamos/yuzu/#how-to-configure-gyro-with-external-controllers

I have tried it personally and managed to get it working with Yuzu in desktop mode but can never get it to work in game mode on my steamdeck. the controller is 8bitdo lite 2

That tutorial, I actually figured that out on my own a while ago. However, this has some disadvantages, it basically forces you to go to Desktop mode and change your Yuzu configuration every time you switch from docked play to mobile play and vice versa. Also when you change gamepads, etc...

In short, the way described there is not really an option for me.

https://github.com/FrogTheFrog/steam-gyro-for-cemuhook May be helpful for Steam Controller

https://github.com/v1993/linuxmotehook2 is also something that might be of interest for you as it handles the the Wii Remotes.

@kmicki is the thought of this for it to be handled with Steam Input support as well for at least he standard controllers?

If you need someone to test all the controllers just send us PM on Discord as we got the most of them and are doing ourself several input experiments with them.

Or if there is anything else we can assist you with.

We are experimenting with trying to build your nice application into RetroDECK:

I have to add that now both FrogTheFrog's application and Ryochan7's fork of sc-controller have been archived. This project is currently the only active endeavor to get the Steam Controller's gyro directly to applications towards the foreseeable future.

Hey @kmicki thanks for your great work. I wanted to passthrough my Dualsense Edge's gyro through to Y*** instead of fighting Steam Input, and stumbled upon the world of CemuHook. It seems like you have pinned the issue last week. When are you planning to work on this? I don't mean to pressure you, just that I thought maybe I could contribute this feature for the Edge, but don't want to duplicate effort if you already picked it up.

Hello @kidoman. Unfortunately I am not able to plan anything in time. I work on issues when I am able to.
You are free to take a look at the linked branch (multi-device). Some refactoring was done there and the steam deck specific code has been extracted into separate classes (look into inc/cemuhook/sdcontroller, src/cemuhook/sdcontroller). The aim would be to create similar classes (implementing DataSource interface) for other controllers. Communication with a HID device has also been made independent of the Steam Deck HID implementation (HidDevReader class), so it may be possible to use it for other controllers.

I appreciate all the efforts on contributing to the project. If I get to work on any specific controller myself, I will make sure to communicate it in this issue.

would also love to see this implemented, unfortunately I couldn't make anything of the code as was suggested by @kmicki
