About

libant-rs is a Rust library for interacting with ANT+ devices. The goal of this library is to provide a simple interface for configuring an ANT+ USB device to allow for device specific channel configuration in order to receive broadcast data from an ANT+ device.

Example

// libant provides the ability to create unbounded Crossbeam channels for passing requests
// to the run loop while receiving data back from the run loop.

let (request_tx, request_rx) = libant::unbounded();
let (message_tx, message_rx) = libant::unbounded();

// This starts our run loop in a separate thread. The run loop can be stopped by sending a Request::Quit message
let run_handle = std::thread::spawn(move || libant::ant::run(request_rx, message_tx));

// Configure a channel for a specific type of device.
use libant::device::hrm::HeartRateMonitor;
use libant::{Request, Response};

let mut hrm = HeartRateMonitor::new();
request_tx.send(Request::OpenChannel(0, HeartRateMonitor::channel_config())).unwrap();

// Now that the channel is open, process any broadcast data messages
loop {
    match message_rx.recv() {
        Ok(Response::BroadcastData(mesg)) => {
            hrm.decode_broadcast_data(mesg.data));
            println!("Heartrate: {}", hrm.heartrate();
        }
    }
}

Testing

Library has been tested on Mac OS X, but should work on any platform that libusb compiles on.

TODOs

• Add support for powermeters (In Progress)
• Add support for electronic trainers
• Add more error handling
