ShuttleControlUSB npm Licence MIT

A Library to use Contour Design ShuttleXpress and ShuttlePro (v1 and v2) in Node.js projects without the driver. In some markets, these devices are also known as Multimedia Controller Xpress and Multimedia Controller PRO v2.

This library now supports multiple devices connected at one time (since v1.1.0). This change is backwards compatible and simply includes a hash of the device id for each event as the final parameter in the callback.

Installation

npm install shuttle-control-usb

Usage

const shuttle = require('shuttle-control-usb');

shuttle.on('connected', (deviceInfo) => {
  console.log('Connected to ' + deviceInfo.name);
});

// Start after 'connect' event listener has been set up
shuttle.start();

API

Methods

start(watchUsb)

  • watchUsb Boolean - whether to monitor for USB devices (true by default)

Starts the service and optionally monitors USB device connections for ShuttleXPress or ShuttlePro (v1 and v2). If watchUsb is true, it will find all connected devices.

This should be called after the 'connect' event listener has been declared, otherwise already-connected devices will not be detected.

connect(path)

  • path String - the device path

If you're not automatically monitoring for USB devices, use this to connect to a specific device by path.

stop()

Stops the service and monitoring. This must be called before your script ends.

getDeviceList()

Use to retrieve all the devices that are connected.

Returns:

  • Object[] - contains the following information:
    • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash, used to distinguish between multiple devices that may be connected at once.
    • path String - the USB device path
    • name String - name of the device ('ShuttleXpress', 'ShuttlePro v1', or 'ShuttlePro v2')
    • hasShuttle Boolean
    • hasJog Boolean
    • numButtons Integer

getDeviceById(id)

  • id String - the device id

Returns Object | null:

  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash, used to distinguish between multiple devices that may be connected at once.
  • path String - the USB device path
  • name String - name of the device ('ShuttleXpress', 'ShuttlePro v1', or 'ShuttlePro v2')
  • hasShuttle Boolean
  • hasJog Boolean
  • numButtons Integer

getDeviceByPath(path)

  • path String - the device path

Returns Object | null:

  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash, used to distinguish between multiple devices that may be connected at once.
  • name String - name of the device ('ShuttleXpress', 'ShuttlePro v1', or 'ShuttlePro v2')
  • hasShuttle Boolean
  • hasJog Boolean
  • numButtons Integer

getRawHidDevice(id)

  • id String - the device id

Returns Object | null - the raw HID device object

Events

shuttle.on('...', () => {})

Event: connected

Emitted when a device has been plugged into a USB port.

Returns Object:

  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash, used to distinguish between multiple devices that may be connected at once.
  • name String - name of the device ('ShuttleXpress', 'ShuttlePro v1', or 'ShuttlePro v2')
  • hasShuttle Boolean
  • hasJog Boolean
  • numButtons Integer

Event: disconnected

Emitted when the device has been unplugged or has failed.

Returns id String - either the serial number (if it exists) or the device path, turned into an MD5 hash.

Event: shuttle

Emitted when shuttle data is available from the device.

Returns:

  • value Integer - Range from -7 to 7 for ShuttleXpress and ShuttlePro (v1 and v2)
  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash.

Event: shuttle-trans

Emitted when shuttle data is available from the device.

Returns:

  • old Integer
  • new Integer
  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash.

Event: jog

Emitted when jog data is available from the device.

Returns:

  • value Integer - Range from 0 to 255 for ShuttleXpress and ShuttlePro (v1 and v2)
  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash.

Event: jog-dir

Emitted when jog data is available from the device.

Returns:

  • dir Integer - Either 1 (clockwise) or -1 (counter-clockwise)
  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash.

Event: buttondown

Emitted when a button is pressed on the device.

Returns:

  • button Integer - the button number
  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash.

Event: buttonup

Emitted when a button is released on the device.

Returns:

  • button Integer - the button number
  • id String - either the serial number (if it exists) or the device path, turned into an MD5 hash.

Enumerations

shuttle.vids

An enumeration of vendor ids for Shuttle devices, namely for Contour Design:

  • CONTOUR

shuttle.pids

An enumeration of product ids for Shuttle devices:

  • SHUTTLEXPRESS
  • SHUTTLEPRO_V1
  • SHUTTLEPRO_V2

Linux Note

By default, the udev system adds ShuttleXpress, ShuttlePro V1, and ShuttlePro V2 as root only access. To fix this, you need to copy 99-Shuttle.rules to:

/etc/udev/rules.d

Then reboot your computer.
