Daktronics All Sport 5000 for Rust

Easily decode the serial output of a console and optionally serialize it.

A Rust implementation of decoders for the Daktronics All Sport 5000's serial output. Please see the documentation for more help.

daktronics-allsport-5000-rs is the most complete library for decoding Daktronics' All Sport 5000 console's serial output in real-time.

This is a Rust library and thus can be installed using Cargo, the Rust package manager. However, a standalone binary is under development for integration in non-Rust workflows.

Note

If you use this crate: let me know about your use case by creating a GitHub discussion or starring! It also lets me know other people find this crate interesting and useful.

Installation

Add this to your Cargo.toml:

daktronics-allsport-5000 = "0.4.0"

Or if you want to use the serde feature:

daktronics-allsport-5000 = { version = "0.4.0", features = ["serde"] }

Or do it with the CLI:

cargo add daktronics-allsport-5000

Cargo features

• Default features: tokio-serial
• tokio-serial: Enables support for serial communication using the tokio-serial crate.
• tokio: Enables asynchronous support using the tokio crate.
• async: Enables support for asynchronous programming, which as of right now only works with Tokio.
• serde: Enables serialization support of sports using the serde crate.

Where is this used?

I made this crate to use in another project I'm working on, daktronics-singular-ui (also open source on GitHub), which allows producers to link together Daktronics All Sport 5000 controllers with a Singular.Live overlay in real time. This powers overlays for Christian Academy in Japan sports livestreams.

Usage

High-level access

Create a new RTDState instance with RTDState::from_serial_stream (available with default features enabled). Get the SerialStream with tokio_serial::new then open_native_async. Check out the examples for more help.

If you need any help, there should be more extensive documentation for each item at docs.rs. Don't hesitate to create a GitHub issue if something is unclear, either.

Sports

This crate supports all sports the control console supports. For a list of them, see the sports module documentation.

Example: getting a sport-specific field

use daktronics_allsport_5000::{
    RTDState,
    // there are lots of other sports available in their respective modules
    sports::basketball::BasketballSport
};
use tokio_serial::SerialPortBuilderExt; // for open_native_async
use crate::daktronics_allsport_5000::sports::Sport; // for rtd_state

#[tokio::main]
async fn main() {
    let serial_stream = tokio_serial::new("/dev/ttyUSB0", 19200)
        .parity(tokio_serial::Parity::None)
        .open_native_async()
        .unwrap();
    let rtd_state = RTDState::from_serial_stream(serial_stream, true).unwrap();
    let mut basketball = BasketballSport::new(rtd_state);

    loop {
        // get the underlying rtd_state to update it
        let update_result = basketball.rtd_state().update_async().await.unwrap();

        basketball.main_clock_time(); // -> Result<&str, ...>
    }
}

Low-level access

When used with the tokio feature, this package provides a tokio-util codec implementing Decoder to decode packets from a serial stream from the control console. That is used internally in SerialStreamDataSource to route data into RTDState.

If you're not using tokio or you're not using a serial stream to deliver the data (e.g. using UDP), you must get the packets somehow yourself, but after that, you can use daktronics_allsport_5000::packet::Packet's TryFrom<bytes::Bytes> implementation to parse the packet into a readable format. Then, you can provide that to the main RTDState struct by implementing daktronics_allsport_5000::rtd_state::data_source::RTDStateDataSource then giving that to RTDState::new. After that, everything works as normal.

Inspiration

The same concept as this crate is also implemented in Python by @FlantasticDan, C# by @JimThatcher, and Python again by @fimion. In fact, the data in this crate is extracted from a PDF provided by @fimion, so thank you!

The offsets of the various fields have been processed from a PDF and typed by hand. If you're interested in porting this crate to another language, check out the Excel spreadsheet I compiled with the data that underpins this crate in ./sports_data.
