colorlight.rs

A Rust library for detecting and sending frames to Colorlight 5A-75 LED receiver cards via Ethernet.

Features

• Detect receiver card
• Send display frames (brightness, color temperature)
• Send row-based pixel data frames (BGR pixel data)

Requirements

• Rust (stable or later)
• Elevated privileges (CAP_NET_RAW or equivalent)
• Network interface connected to the Colorlight 5A-75 card

Installation

Add to Cargo.toml:

[dependencies]
colorlight_rs = { git = "https://github.com/asamonik/colorlight.rs.git", branch = "main" }

Example Usage

use colorlight_rs::ColorlightCard;

fn main() -> std::io::Result<()> {
    let interface_name = "eth0";
    let mut controller = ColorlightCard::open(interface_name)?;

    let info = controller.detect_receiver()?;
    println!("Receiver Info: {:?}", info);

    controller.send_display_frame(0xFF, 0xFF, 0x76, 0x06)?;

    let row_data_bgr: Vec<u8> = vec![0u8; 256 * 3];
    controller.send_row(0, &row_data_bgr)?;

    Ok(())
}
