I recently bought a new 8bitdo switch controller, mainly for the price point and the 6 axis gyroscope
I was quite disappointed seeing the gyro did not work out of the box (not displayed in any emulator, nor antimicrox which is very reliable), but I saw it worked on steam so there was hope
After a little digging, I found that the main controller inputs and the gyroscope (accelerometer) inputs are separated in two special input files.
Doing
evemu-describe /dev/input/by-id/usb-Nintendo.Co.Ltd._Pro_Controller_000000000001-event-if00
displays the accelerometer properties and
evemu-describe /dev/input/by-id/usb-Nintendo.Co.Ltd._Pro_Controller_000000000001-event-joystick
all other inputs
The idea I had was trying to create a new input, which would combine the two previous ones and use this one as my controller, with gyro control
However, while I have coding knowledge I have very little about drivers and input devices and documentation on the internet about all that is very hard to find because it’s a precise topic and search engines are so shitty
So if anyone could help me linking to some documentation or trying to come up with an implementation would be very helpful
this is the output for the two commands
