Nvidia Shield controller

Arfur

Hi, I'm on Rpi3 and retro 4.1.10

I've been trying to get my old Nvidia shield controller working on retropie via usb wire but the configuration only detects buttons in the middle (back, start...) as keyboard.

Any ideas what to do?

@Arfur could try something like https://thund3rm0rph.wordpress.com/2015/12/07/nvidia-shield-controller-on-linux/

Using and tweaking the guide above, I managed to get my Nvidia Shield Controller working via USB and map the buttons in the RetroPie GUI.

I had to add this file, othervise it would not recognize the gampad buttons, only the trackpad:
https://github.com/cyndis/shield-controller-config/blob/master/99-shield-controller.rules

SUBSYSTEM=="input", ENV{ID_MODEL}=="NVIDIA_Controller_v01.03", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1", ENV{ID_INPUT_MOUSE}=""

I put this file in the following location:
/etc/udev/rules.d/99-shield-controller.rules

To activate:
sudo systemctl disable xboxdrv
sudo systemctl stop xboxdrv
sudo systemctl daemon-reload
sudo udevadm control --reload-rules

The trigger buttons registers as an Axis? Guess this is due to the xboxdrv device configuration?

All buttons work fine in the GUI, but when I launch RetroArch I had to manually map the buttons again in the "Settings->Input->Input User 1 Binds" And select "User 1 Device Index: NVIDIA ..."

Then I mapped the buttons accordingly...

Still some tweaking to go, but I'm getting there - using Linux is a learning experience every day ;-)
