DS5Bridge

Windows C++ wrapper for PS5 DualSense controllers — fully Unity-compatible, enabling advanced DualSense features on Windows without a PS5 devkit.

---

Overview

DS5Bridge extends the DS5W Windows driver to provide Unity-safe access to DualSense controller features including:

• Adaptive trigger resistance
• Lightbar color control
• Rumble motors (left & right)
• Player LEDs
• Microphone LED
• Input polling (sticks, triggers, buttons, accelerometer, gyroscope, touchpad, battery)

Designed for developers who want to test or implement DualSense features on Windows without requiring a PS5 devkit.

Purpose: Extend DS5W to support Unity-safe DualSense operations including advanced triggers, microphone input, lightbar, and rumble.

Techniques:

• Thread-safe cached output using a global DS5OutputState g_cachedOutput
• CRITICAL_SECTION locking for hardware writes
• Atomic device updates using setDeviceOutputState(...)
• Continuous resistance trigger profiles via MakeContinuousResistance()

Installation

1. Clone or download this repository:

git clone https://github.com/MrQuazar/DS5Bridge.git

2. Build the DLL using Visual Studio (or use the prebuilt DLL if available).
3. Add the DLL to your Unity project (Assets/Plugins is recommended).
4. Include the C# bridge scripts in your Unity project:
   • DS5Bridge.cs
   • DS5Constants.cs
   • DS5InputCache.cs

Usage in Unity

Initializing the DualSense

using UnityEngine;

public class DualSenseDemo : MonoBehaviour
{
    void Start()
    {
        if (DS5Bridge.Initialize())
            Debug.Log("DualSense initialized!");
    }

    void OnApplicationQuit()
    {
        DS5Bridge.Shutdown();
    }
}

Lightbar

DS5Bridge.SetLightbar(Color.red);   // Red lightbar
DS5Bridge.SetLightbar(Color.green); // Green lightbar

Rumble

DS5Bridge.Rumble(0.5f, 1.0f); // Left 50%, Right 100%

Adaptive Triggers

DS5Bridge.SetTriggerResistance(true, 0, 200);   // Left trigger
DS5Bridge.SetTriggerResistance(false, 50, 150); // Right trigger
DS5Bridge.SetBothTriggerResistance(0, 200, 50, 150); // Both triggers
DS5Bridge.ClearTriggers();                            // Reset triggers

Player LEDs & Mic LED

DS5Bridge.SetPlayerLeds(DS5Constants.PLAYER_LED_LEFT | DS5Constants.PLAYER_LED_MIDDLE_RIGHT);
DS5Bridge.SetMicLed(true);

Reading Input

if (DS5Bridge.TryGetInput(out var state))
{
    Debug.Log($"Left Stick X: {state.leftStickX}, Cross Pressed: {(state.buttonsAndDpad & DS5Constants.BTX_CROSS) != 0}");
}

Using DS5InputCache

Add the DS5InputCache component to a GameObject to automatically poll input each frame:

public class PlayerController : MonoBehaviour
{
    public DS5InputCache inputCache;

    void Update()
    {
        if (inputCache.HasState)
        {
            var state = inputCache.State;
            float moveX = state.leftStickX / 127f;
            float moveY = state.leftStickY / 127f;
            // Use input to move player, rotate camera, etc.
        }
    }
}
