Introduction

Game Controller

ESP32

Arduino

USB HID (human interface device class)

• USB Host Library 2.0.
  • Compatible with Arduino Due only

Some Libraries

• Arduino Joystick Library 2.0
  • Arduino Leonardo or Micro? Will not work with Uno.
  • X, Y, and/or Z Axis (up to 16-bit precision); X, Y, and/or Z Axis Rotation (up to 16-bit precision), etc
• UnoJoy https://github.com/AlanChatham/UnoJoy https://www.youtube.com/watch?v=Rq2QivBzshs
  • DFU mode (Device Firmware Update).
• Arduino XInput Libraries https://github.com/dmadison/ArduinoXInput_AVR
  • the functionality of an Xbox controller.
• PS2 library, eg Arduino-PS2X (?)

Simple keyboard method #include <Keyboard.h> Press buttons?

• Brake: the code presses 'down arrow'
• Left arrow
• Right arrow
• etc

Components

Optical rotary pulse encoder; 600 ppr (pulse per revolution), 100 ppr.

Force Feedback Motor

• An old drill motor: powerful, planetary gearbox to increase torque.
• a brushless motor or a stepper with direct drive (not a geared motor). Absolute encoder.
• RFR Wheel Configuration

Steering ratio

The inner & outer wheel to turn 35 and 30 degrees respectively

Steering ratio

• motorcycles and bicycles 1:1
• most passenger cars between 12 and 20:1
• F1 between 180deg to 270deg to a turn??

Angle

• Drift cars are 900 and 1080 I believe. (Reddit)
• 900 is pretty much around what on a real car.
