API & Documentation

Receiver

The Receiver class constructs objects that represent a single RC Receiver component.

var receiver = new Receiver();

receiver.on("change", function() {
  console.log(this.x, this.y);
});

Options

// Example of explicitly specified address
var receiver = new Receiver({
  address: 0x04
});

* The I2C address defaults to 0x0A, however digital pins 10 & 11 can be used to configure the address, according to the following table:

** The built-in channel names are derived from the most commonly used names in the most common order:

1. throttle
2. aileron
3. elevator
4. rudder
5. gear
6. aux1
7. aux2
8. aux3

When channels: [...] are specified, the length is used to set the channel count and the names provided are used to override the above listed names.

Properties

Iterable/Iterator Protocol

For code running in Node.js 4.2.x or newer, Receiver objects implement the Iterable Protocol.

var receiver = new Receiver();

// Create a zero-indexed array of receiver's current values:
var array = Array.from(receiver);

Events

• change Fired whenever any channel value changes.

• change:[name] Fired whenever the channel matching [name] changes.

  receiver.on("change", function(change) {
    console.log("Channel(%d): %d", change.channel, change.value);
  });

  receiver.on("change:throttle", function(change) {
    console.log("Throttle: %d", change.value);
  });

• data Fired as frequently as the hardware can be read.

Assembly

Connect To I2C Capable Platform

Arduino UNO

var five = require("johnny-five");
var Receiver = require("j5-rc-receiver")(five);
var board = new five.Board();

board.on("ready", function() {
  var receiver = new Receiver();

  receiver.on("change", function(change) {
    console.log("Channel(%d): %d", change.channel, change.value);
  });
});

Tessel 2

var five = require("johnny-five");
var Receiver = require("j5-rc-receiver")(five);
var Tessel = require("tessel-io");
var board = new five.Board({
  io: new Tessel()
});

board.on("ready", function() {
  var receiver = new Receiver({
    // Tessel-IO allow omitting the bus when using Port A, 
    // but for illustrative purposes, we specify it here...
    bus: "A"
  });

  receiver.on("change", function(change) {
    console.log("Channel(%d): %d", change.channel, change.value);
  });
});
