Basic Usage

With A Transport Class

Here's an example using the Serialport class:

// Require your Transport!
const Serialport = require("serialport"); 
// Pass the Transport class to the transport binding 
// function exported by firmata-io. The transport binding
// function will return the Firmata class object with
// the Transport class bound in its scope. 
const Firmata = require("firmata-io")(Serialport);

Firmata.requestPort((error, port) => {
  if (error) {
    console.log(error);
    return;
  }

  const board = new Firmata(port.comName);

  board.on("close", () => {
    // Unplug the board to see this event!
    console.log("Closed!");
  });
});

With A Transport Instance

Here's an example using a Serialport instance:

// Require your Transport!
const Serialport = require("serialport");
// Get the Firmata class without a bound transport. 
const Firmata = require("firmata-io").Firmata;

Serialport.list().then(ports => {
  // Figure which port to use...
  const port = ports.find(port => port.manufacturer.startsWith("Arduino"));
  
  // Instantiate an instance of your Transport class
  const transport = new Serialport(port.comName);

  // Pass the new instance directly to the Firmata class
  const board = new Firmata(transport);

  board.on("close", () => {
    // Unplug the board to see this event!
    console.log("Closed!");
  });
});
