由Coral的出色项目此项目的分支。

此包允许您通过3waylabs的分布式显示协议（DDP）将像素数据写入LED灯带。

您可以用它将像素数据流式传输到WLED或其他任何DDP兼容的接收器。

示例

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(())
}

或者尝试运行cargo run --example dev

它是垃圾吗？

是的。但它对WLED有效，这是我唯一测试和关心的。

为什么？

我想将颜色值流式传输到WLED控制器，DDP是所有我能找到的协议中帧率最高的。
