Fork of this project by the wonderful Coral

This package allows you to write pixel data to a LED strip over Distributed Display Protocol (DDP) by 3waylabs.

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

Example

use anyhow::Result;
use ddp_connection::connection;
use ddp_connection::protocol;

fn main() -> Result<()> {

    let mut conn = connection::DDPConnection::try_new
        (
            "192.168.1.40:4048", // The IP address of the device followed by :4048
            protocol::PixelConfig::default(), // Default is RGB, 8 bits ber channel
            protocol::ID::Default,
            std::net::UdpSocket::bind("0.0.0.0:6969")
                .unwrap() // can be any unused port on 0.0.0.0, but protocol recommends 4048
        )?;

    // loop sets some colors for the first 6 pixels to see if it works
    for i in 0u8..100u8{
        let high = 10u8.overflowing_mul(i).0;

        // loop through some colors

        let temp: usize = conn.write(&vec![
            high/*red value*/, 0/*green value*/, 0/*blue value*/,
            high/*red value*/, 0/*green value*/, 0/*blue value*/,
            0/*red value*/, high/*green value*/, 0/*blue value*/,
            0/*red value*/, high/*green value*/, 0/*blue value*/,
            0/*red value*/, 0/*green value*/, high/*blue value*/,
            0/*red value*/, 0/*green value*/, high/*blue value*/
        ])?;

        std::thread::sleep(std::time::Duration::from_millis(10));
        // this crate is non blocking, so with out the sleep, it will send them all instantly

        println!("sent {temp} packets");
    }

    Ok(())
}

or try it by running cargo run --example dev

Is it trash?

yes. but it works for WLED, and thats all I can test or care about.

Why?

I wanted to stream color values to a WLED controller, and DDP has the highest framerate of any protocol I could find

m8 just open a PR with some gucchimucchi code and I'll review it.
