Haukcode.ArtNet 4.0.90

Haukcode.ArtNet

A high-performance ArtNet library for .NET (8.0+) enabling DMX512 lighting control over IP networks.

What is ArtNet?

Art-Net is a royalty-free protocol for transmitting DMX512 lighting control data over UDP/IP networks. It's widely used in professional entertainment, architectural, and theatrical lighting.

Features

• ✅ DMX transmission and reception
• ✅ Multiple universe support (up to 32,768 universes)
• ✅ Device discovery (ArtPoll)
• ✅ Frame synchronization (ArtSync)
• ✅ RDM support (Remote Device Management) - separate package
• ✅ ArtTrigger for show control
• ✅ High-performance UDP communication
• ✅ Cross-platform (.NET 8.0+)

Quick Start

Installation

dotnet add package Haukcode.ArtNet

For RDM support:

dotnet add package Haukcode.ArtNet.Rdm

Basic Usage

using System.Net;
using Haukcode.ArtNet;

var localIp = IPAddress.Parse("192.168.1.100");
var subnetMask = IPAddress.Parse("255.255.255.0");

// Create client
using var client = new ArtNetClient(localIp, subnetMask);

// Send DMX data
var dmxData = new byte[512];
dmxData[0] = 255; // Channel 1 at full
await client.SendDmxData(null, universeId: 1, dmxData);

Receiving DMX

using System.Threading.Channels;
using Haukcode.ArtNet.Packets;

var channel = Channel.CreateUnbounded<ReceiveDataPacket>();

using var client = new ArtNetClient(
 localIp, subnetMask,
 channelWriter: async (p) => await channel.Writer.WriteAsync(p));

await foreach (var packet in channel.Reader.ReadAllAsync())
{
 if (packet.Packet is ArtNetDmxPacket dmx)
 {
 Console.WriteLine($"Universe {dmx.Universe + 1}: {dmx.DmxData[0]}");
 }
}

Device Discovery

// Send ArtPoll to discover devices
await client.QueuePacketForSending(null, new ArtPollPacket());

Frame Synchronization

// Send data to multiple universes
await client.SendDmxData(null, 1, dmxData1);
await client.SendDmxData(null, 2, dmxData2);

// Sync all outputs
await client.SendSync(null);

Key Methods

// Send DMX data (null = broadcast to all)
Task SendDmxData(IPAddress? address, ushort universeId, 
 ReadOnlyMemory<byte> dmxData, bool important = false)

// Send sync packet
Task SendSync(IPAddress? address)

// Send any packet
Task QueuePacketForSending(IPAddress? destination, 
 ArtNetPacket packet, bool important = false)

Supported Packets

• ArtPoll / ArtPollReply - Device discovery
• ArtDmx - DMX data transmission
• ArtSync - Frame synchronization
• ArtTrigger - Show control triggers
• ArtAddress - Node configuration
• ArtTodRequest / ArtTodData - RDM device discovery
