UnoJoy VS HoodLoader2

I am trying to make the arduino work as an Human Interface Device (HID) for a gaming steering wheel that I am trying to revive, so it would work as a plug and play gamepad. I am shorting the pins in red in this image. I found the Unojoy from their github page here, as far as I understood it is a commonly known library for this kind of project. My main problem with this project is to transform arduino input into game input, thats why I am using a library that should make the arduino pretend to be a gamepad or something of the kind.

I have an Arduino Mega set up with (UnojoyMegajoy)[https://github.com/AlanChatham/UnoJoy], it works pretty well.

There’s also the UnoJoy method, which involves reflashing the firmware on the Mega’s usb controller chip to act as a HID https://github.com/AlanChatham/UnoJoy

UnoJoy

I'm scratch building a dashboard for SnowRunner which I also hope to use for American Truck Simulator, Euro Truck Simulator, Construction Simulator, etc. My current proof of concept includes potentiometers and buttons connected to an Arduino Mega 2560 running UnoJoy over USB to Windows 10 to Toca Edit's X360ce.

I've never used it on console. The project seems abandonned but it was compatible with PS3 https://github.com/AlanChatham/UnoJoy

STEP 5: upload the code to the arduino, my code is: https://pastebin.com/SM1wJ5tk this code is based in UnoJoy project here: https://github.com/AlanChatham/UnoJoy

If it thinks it's an Uno, you can use UnoJoy. It's not quite as easy to use as guitar configurator and may require you to change some values in the code to match pins up

The Mega2560 like the Uno has a second MCU that does the USB-Serial stuff, an atmega16u2. You can flash this one to show up as a USB HID device instead of serial through Hoodloader (https://github.com/NicoHood/HoodLoader2).

The library is compatible with all boards using the MCU ATmega32U4. This includes Arduino Leonardo, SparkFun Pro Micro, Arduino Micro, and Adafruit 32u4 AVR Boards. It also supports the Arduino Uno and Arduino Mega, but this requires the HoodLoader2 bootloader, see this wiki for more details.

hoodLoader2 might help you out. I've no experience with it though.

You should buy a Leonardo if you want to do USB projects, the Uno can do that stuff too - it has a small microcontroller (16u2) that's a cut down version of the one on the Leo (32u4) that handles the USB to serial conversion required for a PC to communicate with the main microcontroller (328P) on an Uno, the 16u2 can be reprogrammed to make the board appear to be anything - but it's harder to achieve for beginners. If you're interested in reading more, take a look at https://github.com/NicoHood/HoodLoader2, but if you just want to do keyboard and mouse stuff quickly with all "off the shelf" hardware and software (and the community support that entails) the Leo is definitely your best bet.
