Crate ddp_rs 

Distributed Display Protocol (DDP) in Rust

This crate allows you to write pixel data to LED strips over the Distributed Display Protocol (DDP) by 3waylabs.

You can use this to stream pixel data to WLED or any other DDP-capable receiver.

Quick Start

use ddp_rs::connection::DDPConnection;
use ddp_rs::protocol::{PixelConfig, ID};
use std::net::UdpSocket;

// Create a connection to your LED controller
let mut conn = DDPConnection::try_new(
    "192.168.1.40:4048",              // Device IP and DDP port
    PixelConfig::default(),            // RGB, 8 bits per channel
    ID::Default,                       // Default ID
    UdpSocket::bind("0.0.0.0:6969")?  // Local socket
)?;

// Send RGB pixel data (2 pixels: red and blue)
conn.write(&[
    255, 0, 0,    // First pixel: Red
    0, 0, 255,    // Second pixel: Blue
])?;

Modules
