Motion evdev: Difference between revisions

Dolphin supports the motion [https://en.wikipedia.org/wiki/Evdev evdev] devices but setting it up is a bit awkward. Nintendo controllers (JoyCon and Pro controller) are supported through the hid-nintendo driver. Sony DualShock4 and DualSense through hid-playstation.

The HID kernel driver exposes 2 (or more) evdev devices, one for the buttons and another for the accelerators/gyroscopes. The hid-nintendo driver exposes the motion axis on an IMU device while hid-playstation named it "Wireless Controller Motion Sensors". Do note that Nintendo Joy-Cons will have 2 devices each (4 in total).

It took me a bit of time figuring out which axis corresponds with the right motion control in dolphin. '''These axis might change in the future when evdev standardizes them.

Select the corresponding Accel or Gyro axis, select it and click ok. For example for ''Accel Up'' in dolphin you need to select ''Accel Z+''. The end result should look like below.
