    node-can

    This is a NodeJS SocketCAN extension. SocketCAN is a socket-based implementation of the CANbus protocol for Linux system.

    This extensions makes it possible to send and receive CAN messages (extended, remote transission) using simple Javascript functions.

    Usage

    Basic CAN example:

    var can = require('socketcan');
     
    var channel = can.createRawChannel("vcan0", true);
     
    // Log any message
    channel.addListener("onMessage", function(msg) { console.log(msg); } );
     
    // Reply any message
    channel.addListener("onMessage", channel.send, channel);
     
    channel.start();

    Working with message and signals:

    var can = require('socketcan');
    var fs = require('fs');
     
    // Parse database
    var network = can.parseNetworkDescription("samples/can_definition_sample.kcd");
    var channel = can.createRawChannel("vcan0");
    var db      = new can.DatabaseService(channel, network.buses["Motor"]);
     
    channel.start();
     
    // Register a listener to get any value changes
    db.messages["CruiseControlStatus"].signals["SpeedKm"].onChange(function(s) {
       console.log("SpeedKm " + s.value);
    });
     
    // Register a listener to get any value updates
    db.messages["Emission"].signals["Enginespeed"].onUpdate(function(s) {
       console.log("Enginespeed " + s.value);
    });
     
    // Update tank temperature
    db.messages["TankController"].signals["TankTemperature"].update(80);
     
    // Trigger sending this message
    db.send("TankController");
