Overview

DoCAN(Diagnostic Communication over Controller Area Network) is a specialized protocol used primarily in automotive and industrial settings.

The driver must implement the CanDriver trait defined in rs-can.

The Server example

fn main() -> anyhow::Result<()> {
    let driver = YourDriver;
    let mut adapter = IsoTpAdapter::new(driver);

    let mut server = DoCanServer::new(adapter.clone(), CHANNEL, Address {
        tx_id: 0x7E8,
        rx_id: 0x7E0,
        fid: 0x7DF,
    });

    adapter.start(100);

    let msg = YourFrame;
    server.adapter().sender().send(msg)?;

    server.service_forever(100)?;
    
    server.service_stop()?;
    
    Ok(())
}

The client example

fn main() -> anyhow::Result<()> {
    let driver = YourDriver;
    let mut adapter = IsoTpAdapter::new(driver);

    let mut client = DoCanClient::new(adapter.clone(), None);
    client.init_channel(CHANNEL, Address {
        tx_id: 0x7E0,
        rx_id: 0x7E8,
        fid: 0x7DF,
    })?;

    adapter.start(100);

    let msg = YourFrame;
    client.adapter().sender().send(msg)?;
    
    client.session_ctrl(CHANNEL, SessionType::Default, true, AddressType::Functional)?;
    client.session_ctrl(CHANNEL, SessionType::Extended, false, AddressType::Physical)?;
    
    Ok(())
}
