Cylon.js For ODROID

Cylon.js (http://cylonjs.com) is a JavaScript framework for robotics, physical computing, and the Internet of Things (IoT) using Node.js.

This module provides an adaptor for ODROID Linux computers (http://www.hardkernel.com/main/main.php).

Supported Odroid Boards

• Odroid XU4
• Odroid XU3

More devices to be added shortly...

How to Install

Installing Cylon.js is easy, and must be done on an Odroid Board with NodeJS.

$ npm install cylon cylon-odroid cylon-gpio cylon-i2c

How to Use

var Cylon = require("cylon");
var odroid = require("cylon-odroid");

// Initialize the robot
Cylon.robot({
  connections: {
    odroid: { adaptor: "odroid" }
  },

  devices: {
    led: { driver: "led", pin: 27 },
    button: { driver: "button", pin:  26, type: "closed"}
  },

  work: function(my) {
    my.button.on('push', function() { my.led.toggle() });
  }
}).start();

How to Use The XU4 ShifterShield

var Cylon = require("cylon");
var odroid = require("cylon-odroid");

// Initialize the robot
Cylon.robot({
  connections: {
    odroid: { adaptor: "odroid", shifterShield: true }
    //You could also invert the ShifterShield pins such that pin 40 = pin 1, pin 39 = pin 2...
    //odroid: {   
    //    adaptor: "odroid", 
    //    shifterShield: {
    //            inverted: true
    //        } 
    //    }
  },

  devices: {
    led: { driver: "led", pin: 27 },
    button: { driver: "button", pin:  26 }
  },

  work: function(my) {
    my.button.on('push', function() { my.led.toggle() });
  }
}).start();

How to Use The XU4 12 Pin Header

var Cylon = require("cylon");
var odroid = require("cylon-odroid");

// Initialize the robot
Cylon.robot({
  connections: {
    odroid: { adaptor: "odroid" },
    con11: { adaptor: 'xu4-12pin' }
  },

  devices: {
    led: { driver: "led", pin: 27 },
    //Set the button to use pin 6 on the 12 pin header
    button: { driver: "button", pin:  6, connection: 'con11' }
  },

  work: function(my) {
    my.button.on('push', function() { my.led.toggle() });
  }
}).start();

How to Use Serial Communication

The Serial driver is a wrapper the node library : serialport. Use as if the driver is the package itself.

var Cylon = require("cylon");
var odroid = require("cylon-odroid");

// Initialize the robot
Cylon.robot({
  connections: {
    odroid: { adaptor: "odroid" }
  },

  devices: {
     serialDevice: { driver: 'serial' } //9600 BaudRate
  },

  work: function(my) {
    my.serialDevice.write('hello \n');
  }
}).start();

Options available

devices: {
 serialDevice: { driver: 'serial', baudRate: 57600, port: '/dev/ttyS0', parser: { byteLength : 5} }
},
//The default port used is the Odroid Boards pin serial port
//Parsers
//Other parsers avaialable
parser: { byteDelimiter: [10,12] }

Commands available are such as:

• write
• pause
• resume
• flush
• close
• update
• set

Looking for a something like serial.available()? listen for the data event instead

my.serialDevice.on('data',function(data) {
  //Do something with the data passed
});

Other events available

• open
• close
• error
• disconnect
