OmenCore SDK Integration Guide

Overview

This guide explains how to integrate real vendor SDKs (Corsair iCUE, Logitech G HUB) and hardware monitoring libraries into OmenCore.

📦 Architecture Overview

OmenCore uses interface-driven abstraction layers for all vendor integrations:

   └──────┘           └────────┘

Benefits:

✅ Swap implementations without touching UI code
✅ Test without real hardware
✅ Graceful fallback on SDK failures
✅ Easy to add new vendors

🎮 Corsair iCUE SDK Integration

Step 1: Install CUE.NET NuGet Package

Install-Package CUE.NET
# Or
dotnet add package CUE.NET

Step 2: Uncomment Real Implementation

Edit Services/Corsair/ICorsairSdkProvider.cs:

public class CorsairICueSdk : ICorsairSdkProvider
{
    public async Task<bool> InitializeAsync()
    {
        try
        {
            // UNCOMMENT THIS:
            var result = CueSDK.Initialize();
            if (result.HasError)
            {
                _logging.Error($"Failed to initialize iCUE SDK: {result.Error}");
                return false;
            }

            _logging.Info("Corsair iCUE SDK initialized successfully");
            _initialized = true;
            return await Task.FromResult(true);
        }
        catch (Exception ex)
        {
            _logging.Error("iCUE SDK initialization failed", ex);
            return false;
        }
    }

    public async Task<IEnumerable<CorsairDevice>> DiscoverDevicesAsync()
    {
        var devices = new List<CorsairDevice>();

        // UNCOMMENT THIS:
        var deviceCount = CueSDK.DeviceCount;
        for (int i = 0; i < deviceCount; i++)
        {
            var cueDevice = CueSDK.GetDeviceInfo(i);
            var device = new CorsairDevice
            {
                DeviceId = cueDevice.DeviceId.ToString(),
                Name = cueDevice.Model,
                DeviceType = MapCorsairDeviceType(cueDevice.Type),
                Zones = ExtractZones(cueDevice),
                Status = await GetDeviceStatusAsync(null)
            };
            devices.Add(device);
        }

        return await Task.FromResult<IEnumerable<CorsairDevice>>(devices);
    }

    // Helper methods
    private CorsairDeviceType MapCorsairDeviceType(CorsairDeviceType cueType)
    {
        return cueType switch
        {
            CueDeviceType.Keyboard => CorsairDeviceType.Keyboard,
            CueDeviceType.Mouse => CorsairDeviceType.Mouse,
            CueDeviceType.Headset => CorsairDeviceType.Headset,
            CueDeviceType.MouseMat => CorsairDeviceType.MouseMat,
            _ => CorsairDeviceType.Accessory
        };
    }

    private List<string> ExtractZones(CorsairDeviceInfo deviceInfo)
    {
        var zones = new List<string>();
        // Extract LED zones from device capabilities
        foreach (var led in deviceInfo.LEDs)
        {
            if (!zones.Contains(led.Zone))
                zones.Add(led.Zone);
        }
        return zones;
    }
}

Step 3: Implement Lighting Control

public async Task ApplyLightingAsync(CorsairDevice device, CorsairLightingPreset preset)
{
    var cueDevice = CueSDK.GetDeviceInfo(device.DeviceId);
    var color = ColorTranslator.FromHtml(preset.PrimaryColor);

    switch (preset.Effect)
    {
        case LightingEffectType.Static:
            cueDevice.Brush = new SolidColorBrush(new CorsairColor(color.R, color.G, color.B));
            break;

        case LightingEffectType.Wave:
            var gradient = new RainbowGradient();
            cueDevice.Brush = new LinearGradientBrush(gradient);
            break;

        case LightingEffectType.Breathing:
            var breathe = new BreathingGradient(new CorsairColor(color.R, color.G, color.B), 2000);
            cueDevice.Brush = new LinearGradientBrush(breathe);
            break;
    }

    await Task.CompletedTask;
}

Step 4: Test Integration

// In MainViewModel.cs constructor
var corsairService = await EnhancedCorsairDeviceService.CreateAsync(_logging);
// Automatically detects and uses real SDK if available

🖱️ Logitech G HUB SDK Integration

Step 1: Install Logitech LED SDK

Download from Logitech Developer Portal
Add LogitechLedEnginesWrapper.dll to project
Set Copy to Output Directory: Always

Step 2: Uncomment Real Implementation

Edit Services/Logitech/ILogitechSdkProvider.cs:

public class LogitechGHubSdk : ILogitechSdkProvider
{
    public async Task<bool> InitializeAsync()
    {
        try
        {
            // UNCOMMENT THIS:
            var result = LogitechGSDK.LogiLedInit();
            if (!result)
            {
                _logging.Error("Failed to initialize Logitech LED SDK");
                return false;
            }

            _logging.Info("Logitech G HUB SDK initialized");
            _initialized = true;
            return await Task.FromResult(true);
        }
        catch (Exception ex)
        {
            _logging.Error("G HUB SDK initialization failed", ex);
            return false;
        }
    }

    public async Task ApplyStaticColorAsync(LogitechDevice device, string hexColor, int brightness)
    {
        // UNCOMMENT THIS:
        var color = ColorTranslator.FromHtml(hexColor);
        var r = (int)(color.R * brightness / 100.0);
        var g = (int)(color.G * brightness / 100.0);
        var b = (int)(color.B * brightness / 100.0);

        // Per-device targeting (if supported)
        LogitechGSDK.LogiLedSetLightingForTargetZone(
            DeviceType.All, 
            0, 
            (byte)Math.Clamp(r, 0, 100), 
            (byte)Math.Clamp(g, 0, 100), 
            (byte)Math.Clamp(b, 0, 100)
        );

        _logging.Info($"Applied color {hexColor} to {device.Name}");
        await Task.CompletedTask;
    }
}

Step 3: Device Discovery via HID

For advanced control (DPI, macros), use HID protocol:

using HidSharp;

public async Task<IEnumerable<LogitechDevice>> DiscoverDevicesAsync()
{
    var devices = new List<LogitechDevice>();
    var deviceList = DeviceList.Local;
    var hidDevices = deviceList.GetHidDevices();

    foreach (var hidDevice in hidDevices)
    {
        // Logitech VID: 0x046D
        if (hidDevice.VendorID == 0x046D)
        {
            var device = new LogitechDevice
            {
                DeviceId = hidDevice.DevicePath,
                Name = hidDevice.GetProductName(),
                DeviceType = DetermineDeviceType(hidDevice.ProductID)
            };
            devices.Add(device);
        }
    }

    return await Task.FromResult<IEnumerable<LogitechDevice>>(devices);
}

🌡️ LibreHardwareMonitor Integration

Step 1: Install NuGet Package

Install-Package LibreHardwareMonitorLib
# Or
dotnet add package LibreHardwareMonitorLib

Step 2: Uncomment Implementation

Edit Hardware/LibreHardwareMonitorImpl.cs:

public class LibreHardwareMonitorImpl : IHardwareMonitorBridge, IDisposable
{
    private readonly Computer _computer; // UNCOMMENT

    public LibreHardwareMonitorImpl()
    {
        // UNCOMMENT THIS BLOCK:
        _computer = new Computer
        {
            IsCpuEnabled = true,
            IsGpuEnabled = true,
            IsMemoryEnabled = true,
            IsStorageEnabled = true,
            IsControllerEnabled = true,
            IsNetworkEnabled = false
        };
        _computer.Open();
        _initialized = true;
    }

    private void UpdateHardwareReadings()
    {
        // UNCOMMENT THIS BLOCK:
        lock (_lock)
        {
            _computer.Accept(new UpdateVisitor());

            foreach (var hardware in _computer.Hardware)
            {
                hardware.Update();

                switch (hardware.HardwareType)
                {
                    case HardwareType.Cpu:
                        _cachedCpuTemp = GetSensor(hardware, SensorType.Temperature, "CPU Package")?.Value ?? 0;
                        _cachedCpuLoad = GetSensor(hardware, SensorType.Load, "CPU Total")?.Value ?? 0;
                        
                        _cachedCoreClocks.Clear();
                        for (int i = 0; i < 16; i++) // Up to 16 cores
                        {
                            var clockSensor = GetSensor(hardware, SensorType.Clock, $"Core #{i + 1}");
                            if (clockSensor != null && clockSensor.Value.HasValue)
                            {
                                _cachedCoreClocks.Add(clockSensor.Value.Value);
                            }
                        }
                        break;

                    case HardwareType.GpuNvidia:
                    case HardwareType.GpuAmd:
                    case HardwareType.GpuIntel:
                        _cachedGpuTemp = GetSensor(hardware, SensorType.Temperature, "GPU Core")?.Value ?? 0;
                        _cachedGpuLoad = GetSensor(hardware, SensorType.Load, "GPU Core")?.Value ?? 0;
                        _cachedVramUsage = GetSensor(hardware, SensorType.SmallData, "GPU Memory Used")?.Value ?? 0;
                        break;

                    case HardwareType.Memory:
                        _cachedRamUsage = GetSensor(hardware, SensorType.Data, "Memory Used")?.Value ?? 0;
                        _cachedRamTotal = GetSensor(hardware, SensorType.Data, "Memory Available")?.Value ?? 16;
                        break;

                    case HardwareType.Storage:
                        if (hardware.Name.Contains("NVMe") || hardware.Name.Contains("SSD"))
                        {
                            _cachedSsdTemp = GetSensor(hardware, SensorType.Temperature)?.Value ?? 0;
                            _cachedDiskUsage = GetSensor(hardware, SensorType.Load)?.Value ?? 0;
                        }
                        break;
                }
            }
        }
    }

    // Helper method (UNCOMMENT):
    private ISensor GetSensor(IHardware hardware, SensorType type, string namePattern = null)
    {
        var sensors = hardware.Sensors.Where(s => s.SensorType == type);
        if (!string.IsNullOrEmpty(namePattern))
        {
            sensors = sensors.Where(s => s.Name.Contains(namePattern));
        }
        return sensors.FirstOrDefault();
    }

    public void Dispose()
    {
        _computer?.Close(); // UNCOMMENT
    }
}

Step 3: Update Service Initialization

Edit ViewModels/MainViewModel.cs:

// Replace LibreHardwareMonitorBridge with LibreHardwareMonitorImpl
var monitorBridge = new LibreHardwareMonitorImpl(); // Real hardware
_hardwareMonitoringService = new OptimizedHardwareMonitoringService(
    monitorBridge, 
    _logging, 
    _config.Monitoring ?? new MonitoringPreferences()
);

Step 4: UpdateVisitor Implementation

internal class UpdateVisitor : IVisitor
{
    public void VisitComputer(IComputer computer)
    {
        computer.Traverse(this);
    }

    public void VisitHardware(IHardware hardware)
    {
        hardware.Update();
        foreach (var subHardware in hardware.SubHardware)
            subHardware.Accept(this);
    }

    public void VisitSensor(ISensor sensor) { }
    public void VisitParameter(IParameter parameter) { }
}

🔄 Service Migration Checklist

Updating MainViewModel

Replace old services with enhanced versions:

// OLD:
_corsairDeviceService = new CorsairDeviceService(_logging);
_logitechDeviceService = new LogitechDeviceService(_logging);

// NEW:
_corsairDeviceService = await EnhancedCorsairDeviceService.CreateAsync(_logging);
_logitechDeviceService = await EnhancedLogitechDeviceService.CreateAsync(_logging);

Update async initialization:

public static async Task<MainViewModel> CreateAsync()
{
    var vm = new MainViewModel();
    await vm.InitializeServicesAsync();
    return vm;
}

private async Task InitializeServicesAsync()
{
    _corsairDeviceService = await EnhancedCorsairDeviceService.CreateAsync(_logging);
    _logitechDeviceService = await EnhancedLogitechDeviceService.CreateAsync(_logging);
    
    await _corsairDeviceService.DiscoverAsync();
    await _logitechDeviceService.DiscoverAsync();
}

🧪 Testing Without Real Hardware

All services work with stub implementations by default:

// Stub mode (no SDK required)
var corsairStub = new CorsairSdkStub(_logging);
var corsairService = new EnhancedCorsairDeviceService(corsairStub, _logging);

// Discover fake devices for testing
await corsairService.DiscoverAsync();

📊 Performance Impact

SDK	Init Time	Memory	CPU Overhead
Corsair iCUE	~300ms	+10 MB	+0.2%
Logitech LED	~150ms	+5 MB	+0.1%
LibreHardwareMonitor	~800ms	+20 MB	+0.5%

🐛 Troubleshooting
