Switch Fightstick Code (Atmega32U4)

This one is a working switch fightstick sketch flashable via Arduino IDE. I personally use it on a pro micro clone microcontroller that can be bought for 2-3$ on aliexpress. My motivation was to have a working solution for dirt-cheap easy source-able parts. Well here it is.

The Code itself has proper Button-Debounce, and 3 Modes of input.

You can switch seamlessly between the 3 modes by pressing START+SELECT.

• Digital Only
• Fake Analog (Digital Movement is mapped to L-Analog)
• Smash Ultimate Mode (Most-left button on the second row of a fight stick is used as a modifier key to decrease the range of the Analog stick, if held)

Building Instructions

• Download Arduino IDE,

• Download the Bounce2 Library inside the Arduino IDE

• Download Arduino Lufa from https://github.com/Palatis/Arduino-Lufa and follow the instructions on it's repository

• Build and Flash for your ATMEGA32U4 Board

• Have Fun
