Prerequisites:

Make sure you installed the ftdi driver: ftdi

If you're are using a Linux distribution or Mac OS X you can run the install.sh script file to install the ftdi driver... For Windows the libs are shipped with this module.

Installation

npm install ftdi

This assumes you have everything on your system necessary to compile ANY native module for Node.js. This may not be the case, though, so please ensure the following are true for your system before filing an issue about "Does not install". For all operatings systems, please ensure you have Python 2.x installed AND not 3.0, node-gyp (what we use to compile) requires Python 2.x.

Windows:

Ensure you have Visual Studio 2010 installed. If you have any version OTHER THAN VS 2010, please read this: https://github.com/TooTallNate/node-gyp/issues/44

Mac OS X:

Ensure that you have at a minimum the xCode Command Line Tools installed appropriate for your system configuration. If you recently upgrade OS, it probably removed your installation of Command Line Tools, please verify before submitting a ticket.

Verify that it is installed by running xcode-select --install

Linux:

You know what you need for you system, basically your appropriate analog of build-essential. Keep rocking!

If you the vendorId and productId are both zero you have to unload the driver before using your node app like this:

rmmod ftdi_sio
rmmod usbserial

Usage

Listing or finding devices

var ftdi = require('ftdi');

ftdi.find(0x27f4, 0x0203, function(err, devices) {}); // returns all ftdi devices with
                                                      // matching vendor and product id

Create an FtdiDevice

var ftdi = require('ftdi');

var device = new ftdi.FtdiDevice({
  locationId: 0,
  serialNumber: 0
});

// or
var device = new ftdi.FtdiDevice(0);  // index in list function

All together

var ftdi = require('ftdi');

ftdi.find(0x27f4, 0x0203, function(err, devices) {
  var device = new ftdi.FtdiDevice(devices[0]);

  device.on('error', function(err) {
  });

  device.open({
    baudrate: 115200,
    databits: 8,
    stopbits: 1,
    parity: 'none',
    // bitmode: 'cbus', // for bit bang
    // bitmask: 0xff    // for bit bang
  },
  function(err) {

    device.on('data', function(data) {

    });

    device.write([0x01, 0x02, 0x03, 0x04, 0x05], function(err) {

    });

  });

});

Bit Bang infos

bitmask: Is always a number (one byte).

bitmode: Can be directly a number (one byte) like 0x20 or a string like 'cbus'.

mapping:

var bitmodes = {
  'reset' : 0x00,
  'async' : 0x01,
  'mpsse' : 0x02,
  'sync'  : 0x04,
  'mcu'   : 0x0B,
  'fast'  : 0x10,
  'cbus'  : 0x20,
  'single': 0x40
};

/**
 * 0x00 = Reset
 * 0x01 = Asynchronous Bit Bang
 * 0x02 = MPSSE (FT2232, FT2232H, FT4232H and FT232H devices only)
 * 0x04 = Synchronous Bit Bang (FT232R, FT245R, FT2232, FT2232H, FT4232H and FT232H devices only)
 * 0x08 = MCU Host Bus Emulation Mode (FT2232, FT2232H, FT4232H and FT232H devices only)
 * 0x10 = Fast Opto-Isolated Serial Mode (FT2232, FT2232H, FT4232H and FT232H devices only)
 * 0x20 = CBUS Bit Bang Mode (FT232R and FT232H devices only)
 * 0x40 = Single Channel Synchronous 245 FIFO Mode (FT2232H and FT232H devices only)
 */

Troubleshoot
