Logitech Dual Action Controller for Node

Provides an EventEmitter with events for the buttons, dpad and analog sticks on the Logitech Dual Action Controller.

Heavily inspired by andrew/node-xbox-controller

Install

 npm install logitech-dual-action-controller

Usage

Step 1. Plug in the controller

Step 2. Add some event listeners

// Create a new one
var controller = new require('logitech-dual-action-controller')()
 
controller.on('1:release', console.log)
 
controller.on('left:move', function (data) {
  // horizontal positon of left analog stick -100 to 100 and 0 at the center.
  var rotateSpeed = data.x
  rotateRobot(rotateSpeed)
})

Events

The dual action has 12 numbered buttons, 1 to 12, a dpad and 2 analog sticks.

Buttons: There are :press and :release events for buttons 1 to 12 like so: 1:press 1:release

Dpad: There are :press and :release events for the dpad directions like so: dup:press, dleft:release. There is a dcenter:press event if you just want to know when they stop pressing the dpad.

Analog sticks: There are left:move and right:move events for the analog sticks, with a data parameter object like { x: 0, y: 0 } representing the position of the stick from -100 to 100 with 0 at the center.

HID info, for them experts.

We get an 8 byte Buffer from each data event.

• byte 0: left analog stick horizontal
• byte 1: left analog stick vertical
• byte 2: right analog stick horizontal
• byte 3: right analog stick vertical
• byte 4: dpad direction and buttons 1,2,3,4
• byte 5: buttons 5,6,7,8,9,10,11,12
• byte 6: mode switch... flips the dpad and left analog stick. 4 is on, 5 is off.
• byte 7: nothing. Seems to always return 252.
