switch-controller's Introduction

switch-controller

Lets you control a switch from your Linux Box

Hardware

Board with either a ATmega16u2 or ATmega32u4
- E.g. A blank Arduino Uno Rev3 or an Adafruit ItsyBitsy 32u4
USB to Serial Converter
- E.g. Another blank Arduino Uno Rev3 or an Adafruit CP2104 Friend

You will need packages dfu-programmer and avr-gcc or avr-libc.

To install these on a Mac with homebrew:

 brew install dfu-programmer
 brew tap osx-cross/avr
 brew install avr-gcc

On Linux Mint 19:

 sudo apt-get install dfu-programmer
 sudo apt-get install avr-libc

Update MCU in the makefile to match your chip, either MCU = atmega16u2 or MCU = atmega32u4.
make
Follow the DFU mode directions to flash Joystick.hex onto the 16u2 of your Arduino UNO R3. Abridged instructions:
- Jumper RESET and GND of the 16u2
```
 sudo dfu-programmer atmega16u2 erase
 sudo dfu-programmer atmega16u2 flash Joystick.hex
 sudo dfu-programmer atmega16u2 reset
```
Install SDL2
- To install these on a Mac with homebrew:
```
 brew install sdl2
```
- On Linux Mint 19:
```
 sudo apt-get install libsdl2-dev
```

Install python libraries pyserial, evdev, PySDL2, and tqdm

 pip install pyserial
 pip install evdev
 pip install PySDL2
 pip install tqdm

Connect the Switch Control board flashed with Joystick.hex to the Switch and the USB to Serial converter to the Linux PC.
Connect the the USB to Serial converter to the Switch Control board
- Example wiring diagram using a second Arduino as a USB to Serial Converter:
Run python bridge.py
- You can see a list of available command line options with python bridge.py -h
- If using a PS3 controller you may need to press the PS button before the controller sends any inputs.
