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 Edison and Intel Galileo IoT platforms. It uses the MRAA node module (https://github.com/intel-iot-devkit/mraa) created by the Intel IoT team thank you!

This module currently supports the following Intel IoT hardware:

• Intel Galileo Gen 1
• Intel Galileo Gen 2
• Intel Edison with the Arduino breakout board

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!

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

• Go to control panel -> network and sharing center -> change adaptor settings
• When you plug both usb cables into your computer, you should see a new network device show up
• Right click on the new device and select properties
• Scroll down to IPv4 and select properties
• Select "Use the following IP address"
• Set the IP information to:
  • IP address: 192.168.2.1
  • Subnet mask: 255.255.255.0
  • Default gateway: 192.168.2.255
  • Preferred DNS server: 8.8.8.8
• Save the changes
• open putty
• ssh to 192.168.2.15
• The user is 'root' and the password is what you configured during the getting started guide

• Install the usb tethering driver http://joshuawise.com/horndis#available_versions
• Open network preferences
• Plug your Edison into your computer
• Find the device Edison
• Configure IPv4: Using DHCP with manual address
  • 192.168.2.1
• Open a terminal
• $ ssh [email protected]

• Examine your /etc/network/interfaces file, if you do not have this line, you must add it and then restart your computer

iface usb0 inet dhcp

• Plug your Edison into your computer
• $ sudo ifconfig usb0 192.168.2.1 255.255.255.0
• $ ssh [email protected]

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!

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.

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.

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

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.

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.

Once you have flashed your Intel board with the latest firmware as well as updated MRAA, you will now install cylon-intel-iot. To do this 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

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

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();

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.

• ssh into your Edison
• # rfkill unblock bluetooth
• # bluetoothctl
  • [bluetooth]# scan on
  • Find your Sphero and take note of the MAC address
  • [bluetooth]# scan off
  • [bluetooth]# pair [MAC address of Sphero]
  • [bluetooth]# exit
• # rfcomm bind 0 [MAC address of Sphero] 1
• This will create a sphero connection bound to /dev/rfcomm0
• # npm install cylon cylon-intel-iot cylon-sphero

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();
