Bean-io

Bean-io is a Firmata-compatibility IO class for writing node programs that interact with LightBlue Bean devices. Bean-io was built at IcedDev

$3

npm install bean-io

In order to use the bean-io library, you will need to load a special version of Firmata onto your
Bean device. Bean Firmata

We recommend you review Punchthrough's Getting Started guide before continuing.

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

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);
});
`

Bean-IO can be used as an IO Plugin for 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();
});
`

$3

`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");

});
});

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