Cylon.js For Intel IoT

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

This repository contains the Cylon adaptor for the Intel Joule, Intel Edison and Intel Galileo IoT platforms. It uses the Galileo-io node module (https://github.com/rwaldron/galileo-io/) created by @rwaldron thank you!

How to Install

To install Cylon.js on your Intel Edison, you must be logged into the board, through ssh or the uart serial connection, and execute the following command:

$ npm install cylon cylon-intel-iot cylon-gpio cylon-i2c

Once cylon-intel-iot and friends have been installed, you're ready to start programming!

Please note that you should flash your Intel board with the latest firmware before installing Cylon.js.

How to Use

Blinking the built in LED

var Cylon = require('cylon');

Cylon.robot({
  connections: {
    edison: { adaptor: 'intel-iot' }
  },

  devices: {
    led: { driver: 'led', pin: 13 }
  },

  work: function(my) {
    every((1).second(), my.led.toggle);
  }
}).start();

Setting up your Intel Edison

Everything you need to get started with the Edison is in the Intel Getting Started Guide located here. Don't forget to configure your Edison's wifi connection and flash your Edison with the latest firmware image (Yocto 3)!

Updating Node.js on the Intel Edison

The Intel Edison has an older Node.js (0.10.x) installed by default. You can easily update it using Node Version Manager (nvm).

The latest Yocto needs to update the version of the tar file decompression utility before you can install new versions of Node.js using nvm. You can easily do this as follows. First, add the "unofficial official" package repository:

echo "src/gz all http://repo.opkg.net/edison/repo/all
src/gz edison http://repo.opkg.net/edison/repo/edison
src/gz core2-32 http://repo.opkg.net/edison/repo/core2-32" > /etc/opkg/base-feeds.conf
opkg update

Thanks to http://alextgalileo.altervista.org/edison-package-repo-configuration-instructions.html for the above instructions.

Once you have added the additional package repository, run the following commands:

opkg install tar
touch ~/.profile

You are now ready to install nvm on your Edison. Follow the nvm installation instructions here.

How to Connect

The Intel Edison Getting Started Guide details connection instructions for Windows, Mac and Linux.

In order to enable Ethernet over USB on your Edison, follow the appropriate guide for your OS

Windows
OS X
Linux
iface usb0 inet dhcp

The Edison is now able to use it's wifi connection to reach the internet and your local USB to Ethernet connection for local ssh access and programming. If you have problems reaching the internet, you may need to setup the DNS on your Edison.

Execute the following command on the Edison itself

# cat "nameserver 8.8.8.8 > /etc/resolv.conf"

If you have a valid wifi connection, you should be able to reach out of your network!

Ethernet over USB internet sharing

If you are using ethernet over USB then you can enable internet sharing on your Edison by executing this command on the Edison itself

/sbin/route add default gw 192.168.2.1

Now you're ready to install MRAA and Cylon.

Setting up your Intel Galileo

In order to use cylon-intel-iot on your Galileo, you need to install the Intel IoT linux boot image onto an sd card. You can download the latest image here.

For Windows hosts you can follow the instruction for flashing your sd card image here.

For Mac or Linux hosts, it's as easy as extracting the image from the downloaded archive and executing the command

$ sudo dd if=/path/to/iot-devkit-latest-mmcblkp0.direct of=/dev/sdX bs=1M && sudo sync

where /dev/sdX is the location of your sd card. For help determing the location of your sd card, consult the appropriate guide for your OS below.

OS X Users

To prepare your SD card for flashing on OS X, you need to find out it's drive name and eject the volume.

To find the name, use the built-in diskutil utility:

$ diskutil list
/dev/disk0
  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:      GUID_partition_scheme                        *500.3 GB   disk0
  1:                        EFI EFI                     209.7 MB   disk0s1
  2:                  Apple_HFS Macintosh HD            499.4 GB   disk0s2
  3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
/dev/disk1
  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:     FDisk_partition_scheme                        *15.7 GB    disk1
  1:             Windows_FAT_32 NO NAME                 15.7 GB    disk1s1

According to this, our SD card is found at /dev/disk1.

Before you flash it with the above dd command, use diskutil to eject the existing volume (disk1s1):

$ diskutil unmount /dev/disk1s1
Linux Users

To prepare your SD card for flashing on Linux, you need to find the device location of your SD card. An easy way to determin the location is by filtering the /dev/ directory for new storage devices. Before you plug in your SD card, execute the following ls command

$ ls -l /dev/sd*
brw-rw---- 1 root disk 8,  0 Sep 16 21:48 /dev/sda
brw-rw---- 1 root disk 8,  1 Sep 16 21:48 /dev/sda1
brw-rw---- 1 root disk 8,  2 Sep 16 21:48 /dev/sda2
brw-rw---- 1 root disk 8,  5 Sep 16 21:48 /dev/sda5

You can see that I only have one storage device /dev/sda. Now plug in your SD card and execute the ls command again

$ ls -l /dev/sd*
brw-rw---- 1 root disk 8,  0 Sep 16 21:48 /dev/sda
brw-rw---- 1 root disk 8,  1 Sep 16 21:48 /dev/sda1
brw-rw---- 1 root disk 8,  2 Sep 16 21:48 /dev/sda2
brw-rw---- 1 root disk 8,  5 Sep 16 21:48 /dev/sda5
brw-rw---- 1 root disk 8, 16 Sep 17 17:46 /dev/sdb
brw-rw---- 1 root disk 8, 17 Sep 17 17:46 /dev/sdb1
brw-rw---- 1 root disk 8, 18 Sep 17 17:46 /dev/sdb2

You can see from this output that I now have a new storage device /dev/sdb. That is the location of my SD card, so in this instance the /dev/sdX in our dd command will be /dev/sdb.

After the image has been flashed to your sd card, install the sd card into the Galileo, connect it to your local network and power it up!

Now you're ready to install MRAA and Cylon.

Install MRAA

After you have flashed your Intel board and connected it to a network, you must now install the latest version of the Intel MRAA library. In order to update MRAA you simply log into your Intel board, through ssh or the uart serial connection, and follow the steps here.

Bluetooth Programming on the Intel Edison featuring Sphero

The Edison includes a bluetooth radio right on the board itself, so it's easy to get started programming bluetooth devices out of the box. First we need to enable bluetooth on the Edison.

This example will flash the built in LED whenever the Sphero detects a collision

var Cylon = require('cylon');

Cylon.robot({
  connections: {
    edison: { adaptor: 'intel-iot'},
    sphero: { adaptor: 'sphero', port: '/dev/rfcomm0' }
  },

  devices: {
    led: { driver: 'led', pin: 13, connection: 'edison' },
    sphero: { driver: 'sphero', connection: 'sphero' }
  },

  work: function(my) {
    console.log("Setting up Collision Detection...");
    my.sphero.stop();
    my.sphero.detectCollisions();

    my.sphero.on('collision', function() {
      console.log("Collision");
      my.led.toggle();
    });
  }
}).start();
