Nintendo Switch AutoXinput (or NX-AX) is a set of Arduino files to "emulate" a Nintendo Switch Pro Controller

NX-AX

The following is required:

• The Arduino XInput Library (https://github.com/dmadison/ArduinoXInput)
• A Arduino board compatible with ArduinoXInput (in my case, a Arduino Leonardo)
• A Mayflash MAGIC-NS (https://www.amazon.com/Mayflash-MAGIC-NS-Wireless-Controller-Nintendo-Switch/dp/B074JZPS39)

The following is optional:

• Another Arduino board to act as a master (in my case, a Arduino Mega 2560)

Nintendo Switch AutoXInput (or NSAXI) is a set of Arduino files to "emulate" a Nintendo Switch Pro Controller. This uses the XInput support of the Mayflash Magic-NS to output Nintendo Switch Pro Controller inputs, allowing automatic and nearly TAS-like inputs. TAS-like because this project is in HEAVY devolpment and is no where near production. There is spaghetti code. There is code that makes no sense. I am aware and am always accepting pull requests.

nx-ax's Issues

Request Advice — Raspberry Pi / Pico

Hey @EpicKitten thank you for putting this online; and thank you for the inspiration 🙌.

I know you've build this for arduino. I try to get away from arduino to just have one base system flying around in my house... So if you don't mind, I'd like to ask if you have any advice / pointers to look into. I'm new to systems engineering.

Regarding approach in combination with the Mayflash

• Do you have an idea / link how you would send XInput directly via a Raspberry PI 4 (4 supports USB host 1.1) or Pico?
• The Mayflash says it has DINPUT (not sure what it exactly means); might that be a better fit in combination with the Raspi (I'm not sure why you used XInput; I don't have yet the Mayflash)
• The Magic-S Pro has wireless... maybe a way to ditch the cables?

Skipping Mayflash

• Are you aware of a library / way of implementation to skip the mayflash and directly emulate a switch controller? (Since this repo was last updated 15 months ago, maybe you learned something new)

What I am up to: Automate Video Conversion for Super Smash Bros Ultimate (SSBU) via Computer Vision
Since 1998 I play smash. If you played SSBU you may know, that you can save replays. Those need to be converted one by one into Videos (life is hard). Since I am in the product and machine learning space, I just want to put a webcam (or smartphone) over the switch and have "the AI" deal with the problem of going through the menus, watch every replays and convert all of them into video while doing so — reading from the screen / realizing when the replay is done without my help etc etc. For that I need to get controller input into the switch — so I am searching for elegant solutions to this. Also a fun pandemic side project 😋

Ideal scenario would be to just plug / connect an iOS / Android phone into a pico (or similar) and have the device connect to the switch. Than run the AI / Computer Vision inside the App on the phone.

All the best from Berlin
