servicepoint

In CCCB, there is a big pixel matrix hanging on the wall. It is called "Service Point Display" or "Airport Display". This crate contains a library for parsing, encoding and sending packets to this display via UDP.

This project moved to git.berlin.ccc.de/servicepoint/servicepoint. The GitHub repository remains available as a mirror.

Examples

fn main() {
    // establish connection
    let connection = servicepoint::Connection::open("172.23.42.29:2342")
        .expect("connection failed");

    // clear screen content
    connection.send(servicepoint::Command::Clear)
        .expect("send failed");
}

More examples are available in the crate. Execute cargo run --example for a list of available examples and cargo run --example <name> to run one.

Installation

cargo add servicepoint

[dependencies]
servicepoint = "0.13.1"

Note on stability

This library can be used for creative project or just to play around with the display. A decent coverage by unit tests prevents major problems and I also test this with my own projects, which mostly use up-to-date versions.

That being said, the API is still being worked on. Expect minor breaking changes with every version bump. Please specify the full version including patch in your Cargo.toml until 1.0 is released.

This library has multiple optional dependencies. You can choose to (not) include them by toggling the related features.
