Install the Arduino Joystick Library from by Matthew Heironimus: 16 | 17 | * Repository: https://github.com/MHeironimus/ArduinoJoystickLibrary 18 | * Direct Download: https://github.com/MHeironimus/ArduinoJoystickLibrary/archive/master.zip 19 | 20 | If your IDE is using default directories, you can execute the deploy.bat to Install the library, otherwise you need to copy the Joystick directory into your Arduino/libraries directory manually. 21 | 22 | ### 2. Download and Deploy to Handbrake Arduino 23 | 24 | Download / Clone this repository or just the sktech and open the "ChineseHandbrakeCustomFirmware.ino" with your Arduino IDE: 25 | 26 | * Sketch Only: https://raw.githubusercontent.com/Dakor91/Chinese-SimRacing-14Bit-Handbrake-Custom-Firmware-Arduino-Sketch/master/ChineseHandbrakeCustomFirmware.ino 27 | * Repository: https://github.com/Dakor91/Chinese-SimRacing-14Bit-Handbrake-Custom-Firmware-Arduino-Sketch/archive/master.zip 28 | 29 | Then... 30 | 1. Conntect your Handbrake and select the corresponding COM port of the device, which will be titled "Arduino Leonardo". 31 | 1. Select "Arduino Leonardo" as the Board Type. 32 | 1. Compile and Deploy the Sketch. 33 | 34 | Done! 35 | 36 | 37 | # Technical Details 38 | 39 | Within the handbrake there's a simple PCB with an Arduino Pro Micro and a Hall Sensor. \ 40 | On the pcb titled *version 3.0* the hall sensor is conntector to GND, VCC and A2. The PCB has another lead to pin 10, but it's not connected to anything else, due to a missing resistor. 41 | Pin 3 and pin 1 of the arduino were also soldered on my board, but there are no leads going anywhere. To be sure I measured both and found that they are not connected to anything that's measurable on the pcb. I assume they are just soldered for stabilization. 42 | 43 | Top View of the v3 PCB 44 | 45 | [Top View of the v3 PCB](14bit%20v3%20images/pcb_v3_top_anot.jpg?raw=true "Top View of the v3 PCB") 46 | 47 | Bottom View of the v3 PCB 48 | 49 | [Bottom View of the v3 PCB](14bit%20v3%20images/pcb_v3_bottom_anot.jpg?raw=true "Bottom View of the v3 PCB") 50 | 51 | **Note: I know that there's at least a version 4.0 of this PCB, but I don't know the exact differences.** 52 | --------------------------------------------------------------------------------
