# Bean-io

Bean-io is a Firmata-compatibility IO class for writing node programs that interact with [LightBlue Bean devices](http://punchthrough.com/bean/). Bean-io was built at [IcedDev](http://iceddev.com/)

### Installation

`npm install bean-io`

### Getting Started

In order to use the bean-io library, you will need to load a special version of Firmata onto your
Bean device. [Bean Firmata](https://github.com/jacobrosenthal/arduino/blob/bean/examples/StandardFirmata/StandardFirmata.ino)

We recommend you review [Punchthrough's Getting Started guide](http://punchthrough.com/bean/getting-started/) before continuing.

### Linux Instructions

Make sure that libbluetooth-dev and bluez libraries are installed before installing bean-io.

### Blink an Led

The "Hello World" of microcontroller programming:

```js
var beanio = require("bean-io");
var board = new beanio.Board({
  timeout: 30000 //optional - defaults to 30 seconds
  // uuid: 'myUuid' //optional - will use first bean found
});

board.on("ready", function() {
  console.log("CONNECTED");
  this.pinMode(13, this.MODES.OUTPUT);

var byte = 0;

// This will "blink" the on board led
  setInterval(function() {
    this.digitalWrite(13, (byte ^= 1));
  }.bind(this), 500);
});
```

### Johnny-Five IO Plugin

Bean-IO can be used as an [IO Plugin](https://github.com/rwaldron/johnny-five/wiki/IO-Plugins) for [Johnny-Five](https://github.com/rwaldron/johnny-five):

```js
var five = require("johnny-five");
var beanio = require("bean-io");
var board = new five.Board({
  io: new beanio.Board()
});

board.on("ready", function() {
  var led = new five.Led({pin: 13});
  led.blink();
});
```

### Use ble-bean and Johnny-Five Api Together

```js
var five = require("johnny-five");
var beanio = require("bean-io");
var boardIO = new beanio.Board({
//    name: "ZAPP" // optional: you can specify a localName otherwise defaults to nearby bean
});

var board = new five.Board({
  io: boardIO
});

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

var button = new five.Button(12); // button on pin 4

button.on("down", function() {
    console.log("down");
    boardIO.connectedBean.setColor(new Buffer([0, 64, 64]), function(err){
      console.log('set color on', err);
    });
  });

button.on("hold", function() {
    console.log("hold");
    boardIO.connectedBean.setColor(new Buffer([0, 0, 0]), function(err){
      console.log('set color off', err);
    });
  });

button.on("up", function() {
    console.log("up");

});
});
```

### API

Bean-IO subclasses firmata.js and provides the same API.

### Pin Mappings

Bean to Arduino UNO
