Use Wii Nunchuck as Motion-Controller

Post by Nokiator0815 » Sat May 12, 2018 3:47 pm

Hi,
i like the possibility to use a mouse for precise aiming in PS4 games, but i don’t like to play games with the keybord (Here is my GIMX-Setup https://gimx.fr/forum/viewtopic.php?f=3&t=2556).
So i built my Motion-Controller from a Wii Nunchuck. Now I want to share my idea with you.

Image

The Components:
1) Nintendo Wii Nunchuck or Clone
- analog Joystick
- 2 buttons
- 3-axis accelerometer
2) SNES Classic Controller/Nunchuck Extension Cable
- used only the socket side
3) ATmega32u4-Board (Pro Micro 5V 16MHz)
- since the nunchuck works with 3V, a I2C level converter with integrated dc-dc-converter was used
- a piece of software to convert the I2C data to USB-HID
4) micro USB cable

In this setup the Wii Nunchuck works like a normal Joystick with Windows and Linux (no special drivers necessary).

There are 2 axes from the Joystick and 2 axes from the accelerometer (pitch and roll). Also there are 2 physical buttons and 6 „buttons“ generated from the accelerometer (swing the nunchuck in 6 directions).
It's really fun and a more dynamic gameplay, for example, to push the fist with the Nunchuck to the front to do a glory kill in doom, or swing the nunchuck up or down to jump or crouch. The roll-axis can be used for steering, or pitch and roll for flying. There are many possibilities.

Hello,

Thanks for the tutorial! We're always happy when someone uses gimx successfully and we love when you find a new ways to play!

This post contains a lot of useful info so I will move it to the Tutorials section if you don't mind :)
