VR steam controllers driver

VR-Driver Project

Custom VR controller driver for SteamVR. Receives UDP data from external controllers (Arduino or mobile devices) and converts it into VR controller input.

Quick Start

Prerequisites

• Install ALVR (GitHub Releases)
• Install PhoneVR (ALVR-compatible version)
• Install SteamVR via Steam

Installation

C:\Program Files (x86)\Steam\steamapps\common\SteamVR\drivers\cvdriver\

Hardware Setup

PCB Ordering

• Manufacturer: PCBWay
• Gerber files: kicad/gerber/gerber.zip
• Assembly guide: smd-placement.pdf
• Print dimensions: print_scheme_sizes.pdf

ArUco Marker Generation

pip install -r requirements.txt
python generate_aruco.py

Markers generated: aruco_marker_0.png – aruco_marker_9.png

How It Works

• UDP server listens on port 5555
• Receives controller sensor data
• Converts data to SteamVR input
• Updates controller states in real time

Data Packet Format

struct ControllerData {
    uint8_t controller_id;
    uint32_t packet_number;
    float quat[4];
    float accel[3];
    float gyro[3];
    uint16_t buttons;
    uint8_t trigger;
    uint8_t checksum;
};
