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
npm install logitech-dual-action-controllerStep 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)
})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.
