Emulating Xinput, what are the requirements?

blitz0145

Hello,

I'm looking to get XInput working on the nRF52840 so that our device can appear as an Xbox-compatible game controller. I'd appreciate any guidance or recommendations on how to approach implementing a custom feature like this on the Nordic platform.

Thank you in advance for your help!

    If you are wiring XInput on the nRF52840 through Zephyr rather than TinyUSB, those Alpakka HID descriptors still map pretty cleanly onto one of the NCS USB samples. I would start from the HID sample, swap in the XInput report map, then confirm the device enumerates as a gamepad on Windows before you chase Zephyr USB stack quirks.

    I test HID/gamepad USB bits off the bench a lot now. Rent Yachts Thai if you ever need a quieter place than the lab to catch a firmware flash over DAZN-length waits.
