ESCs

The ESCs class constructs a collection object containing multiple ESC objects. Any method called on an ESCs object will be called on each member of the ESCs object with the same parameters.

• ESC

Parameters

• numsOrObjects An array of pins, ESC parameter objects and/or ESC objects:

  Property	Type	Value/ Description	Default	Required
  numsOrObjects	Array	An element for each ESC. Any valid ESC parameters will work		yes

Component Initialization

###With Pins

// Create two basic ESCs
//
new five.ESCs([9, 10]);

###With Objects

// Create two ESCs
//
new five.ESCs([{
  pin: 9
}, {
  pin: 10
}]);

Usage

Control all members simultaneously:

var five = require("johnny-five");
var board = new five.Board();

board.on("ready", function() {

  var escs = new five.ESCs([3, 5]);

  // Set all ESCs to max.
  escs.throttle(100);
});

Control a single ESC in an ESCs instance:

var five = require("johnny-five");
var board = new five.Board();

board.on("ready", function() {

  var escs = new five.ESCs([9, 10]);

  // Set the ESC on pin 9 to 90% of max speed.
  escs[0].throttle(90);
});

Using multiple controllers in a single ESCs instance:

var five = require("johnny-five");
var board = new five.Board();

board.on("ready", function() {

  var escs = new five.ESCs([
    { controller: "PCA9685", pin: 0 }, // Attached to an Adafruit PWM shield
    { pin: 3 } // Attached directly to the Arduino
  ]);

  // Set both escs to 75% of max speed.
  escs.throttle(75);
});

Using ESC objects in ESCs:

var five = require("johnny-five");
var board = new five.Board();

board.on("ready", function() {

  var escA = new five.ESC(9);
  var escB = new five.ESC(10);

var motors = new five.ESCs([escA, escB]);

  // Set ESCs independently
  escA.throttle(20);
  escB.throttle(90);

  // Set all ESCs to max speed.
  escs.throttle(100);

});

API

All methods and properties in the ESC API are available on ESCs

Events

Events are emitted on the individual ESC objects so listeners must be attached there. See ESC events
