Overview

This article shows those new to electronics how to install, configure, and use the Intel Edison board and XDK IDE for simple projects. Instructions are for Apple Mac.

I want you to feel confident that you’ve mastered this skill. That’s why this takes a hands-on approach where you type in commands and we explain the responses and possible troubleshooting. This is a “deep dive” because all details are presented.

Like a good music DJ, I’ve carefully arranged the presentation of concepts into a sequence for easy learning, so you don’t have to spend as much time as me making sense of the flood of material around this subject.

Sentences that begin with PROTIP are a high point of this website to point out wisdom and advice from experience. NOTE point out observations that many miss. Search for them if you only want “TL;DR” (Too Long Didn’t Read) highlights.

Stuck? Contact me and I or one of my friends will help you.

IoT Hardware Basics

Intel boards are based on Intel’s X86 architecture, Raspberry Pi and Beaglebone are based on the alternative 3.3V ARM 11 chip architecture.

Intel boards do not have an HDMI video port like a Raspberry nor keyboard port like on PCs.

The Galileo was Intel’s initial board. It does not have on-board WiFi. It has the same form factor as the Edison board released in 2014.

https://www.youtube.com/watch?v=GY8kaaFzbTE

Both the Galileo and Edison have pinouts compatible with 5V Arduino boards, so a shield such as Grove can be integrated. The Grove is a co

Intel Edison is a dual-core Silvermont Atom(TM) clocked at 500MHz. It’s called a System on a Chip (SoC) because it packs so many capabilities: 4GB of storage (plus micro SD card slot), 1GB RAM

NOTE: The Edison has on-board WiFi and Bluetooth, so cost $50 vs. $35 for the Arduino UNO which require additional hardware for WiFi and Bluetooth, but it has Analog I/O.

  • PDF: Hardware Guide: Intel® Edison Kit for Arduino from here contains a block diagram, header signal list, and other details. The board supports 40 GPIOs and includes 1 GB LPDDR3, 4 GB EMMC, and has dual-band WiFI and BTLE.

  • The Intel® Edison kit for Arduino has a 100 mA charging current.

  • The Intel® Edison Breakout Board has a 190 mA charging current.

PROTIP: The Edison runs 1.8V logic with current drive of 3mA. (lower power than TTL or CMOS on other boards) Not enough to power an LED.

This Intel Arduino breakout also has an SD card connector, micro USB or standard sized

Intel also has a Mini Breakout board. Get your first “blink” LED on the mini breakout board.

Intel’s Gateway is hardware and software that collects data from IoT devices for aggregation in a cloud service, which provides analytics.

First project

  • Blink an on-board LED does not require additional items. So this “embedded app” project is a good first project to get familiar with the basics working.

  • Follow instructions here to create a temperature monitoring app using Intel® XDK receiving temperature from a sensor connected via a Grove* Cable plugged into a Grove Base Shield.

Sensors

intel iot xdk sensors 20160813-166x536-i10

The sensors and other components Intel supports are listed at: https://software.intel.com/en-us/iot/hardware/sensors, where code samples are provided for each component in C/C++, JavaScript, and Python programming languages. Code is also included in Intel’s XDK IDE, accessed from its “IoT Sensor Library Explorer” shown at right (described in a later section).

The wiki page for each sensor, actuator, etc. are listed below.

The “SeeedStudio Grove starter kit plus for Intel Edison IoT Edition” $79 provides a set of common sensors as well as an Arduino UNO R3 (layout with 4 PWM instead of 6 PWM) expansion board. It hooks on top of an Arduino 101 breakout board. Its use with the special Grove cable means no soldering is needed to use the 6 analog inputs, and 20 ditial input/output pins.

Sensors

Actuators:

Additional sensors from Grove include:

  • Barometer
  • Infrared temperature Sensor
  • $40 GPS module
  • CO2
  • Gas sensor

  • Compass
  • Color Sensor tcs3414cs

  • GSR (Galvanic Skin Response) measures electrical Conductance on a finger. Eelectrical Modle</a> Sensitivity is adjusted via a potentiometer. Strong emotion can cause stimulus to your sympathetic nervous system, resulting more sweat being secreted by the sweat glands. Grove – GSR allows you to spot such strong emotions by simple attaching two electrodes to two fingers on one hand, an interesting gear to create emotion related projects, like sleep quality monitor.

  • Weather Shield (relative humidity, barometric pressure, temperature, light intensity)
  • $80 Weather Meters (Wind Vane, Cup Anemometer, Tipping Bucket Rain Gauge)

Projects

Among projects described in websites:

these:


Connect power

  1. CAUTION: Discharge static before you touch anything.

  2. Handle PCB (Printed Circult Boards) by the edges.

  3. The switch on the top edge of the board should be toggled to 5V.

  4. The switch among the plugs (1 in the diagram) should be toggled to whatever side is plugged in.

    PROTIP: It’s best to power your Intel® Edison board with the external DC power supply, with the round barrel connector (4 on the diagram).

    PROTIP: However, plug in a USB cable from a USB 3.0 port on your host computer (laptop) to the middle USB connector on the board to provide current to drive the LCD display.

  5. Slide the micro-switch “SW1” (multiplexer USB 2.0 OTG interface) toward the USB Type micro-B (the small one that goes into mobile phones) to select device mode.

    Slide the micro-switch toward the larger USB Type A recepticle for to select device mode operation.

Remote operation

It is possible to have the Edison operate remotely off solar and battery power. A battery is needed evenings and on cloudy days.

Sparkfun.com has this set of components:

Connect to PC

The Edison board provides several ways to move data.

There are several build-in commands that can be used to connect your PC to the board, described below. If you installed Bloop, connect with a single utility command:

bloop c

This automatically connects you via “screen” to an attached Edison device.

### Install Bloop #

https://www.npmjs.com/package/bloop
is a set of command-line tools for working with Intel Edison on the PC (laptop) side.

  1. Install bloop globally:

    npm install -g bloop

    The response:

    /usr/local/Cellar/node/6.3.0/bin/bloop -> /usr/local/Cellar/node/6.3.0/lib/node_modules/bloop/bloop.js
    /usr/local/Cellar/node/6.3.0/lib
    └─┬ bloop@0.1.3 
      ├── commander@2.5.1 
      └─┬ promptly@0.2.1 
     └─┬ read@1.0.7 
       └── mute-stream@0.0.6 
    

    Read about its commands from its creator Rex St. John (@rexstjohn)

    BLAH: After install, I got a “command not found”. So we’re sticking with built-in commands below.

    Serial connection

  2. Connect a USB cable to the micro-USB port at 2 on the diagram.

    by Intel Evangelist Daniel Holmlund (@agnathan)

    Alternately, for Windows

    PROTIP: On a Mac, plug in BOTH mico-USB cables.

  3. Open a Terminal shell window. Alternately, take the manual approach:

  4. List UART devices connected on /dev/ttyMFD1.

    ls /dev/tty.*

    The response is like:

    /dev/tty.Bluetooth-Incoming-Port	/dev/tty.usbserial-A90400YX
    

    NOTE: The “A90400YX” in this example will be different on your device.

  5. Highlight and copy the part such as “/dev/tty.usbserial-A90400YX” and paste to assemble this command:

    screen /dev/tty.usbserial-A90400YX 115200 -L

    • The 115200 specifies the “baud” speed of communications (the highest theorectical maximum of 230,400 bits per second).

    • The -L flag turns on output logging.

    TROUBLESHOOTING: If “Sorry, cannot find a PTY”, try closing the terminal, open another terminal, power down the board, and bring it up again.

  6. Press Enter when the blank terminal appears.
    Press Enter twice for the Edison board.

    The response should be something like this:

    Poky (Yocto Project Reference Distro) 1.7.3 edison ttyMFD2
     
    edison login: 
    

    NOTE: The “edison” above is the name of the board setup before.

  7. Type root. There is no other user name on the Edison.

    A new board would have no password.

  8. If a password prompt appears, one was specified by a previous user. If you don’t know the password, flash the firmware again (see below).

    Sucess is this line (but instead of “edison”, your user name would appear):

    root@edison:~# _
    

    Skip to verify version or MRAA install.

    PROTIP: When exiting from a screen session, press Ctrl + D to detach cleanly.

Firmware download

PROTIP: The device you have may have obsolete firmwware.

DEFINITION: Firmware is the operating system of embedded microcontrollers.

Flashing is the process of overwriting the firmware on the board’s memory, much like applying system updates on your computer.

Mac El Capitan

I wasted several days scratching my head until I finally tweeted @inteliot and (my hero) Rex St. John (who also wrote bloop) replied (on a Friday evening). Rex is the author of this blog and these instructions which got me going on El Capitan (the latest OS on Mac OSX).

  1. Open Mac’s Spotlight (“Command + Space Bar”).
  2. Type “Disk Utility”
  3. Erase (re-format) the EDISON to “MS-DOS (FAT)”.

  4. Install these:

    brew update
    brew install dfu-util coreutils gnu-getopt
    brew tap jlhonora/lsusb
    brew install lsusb

    At the Intel® Edison Module Downloads page, rather than using the integrated “Installers” GUI program (Intel_Edison_Setup_Mac_v2016.2.013), I

  5. click to download the “Latest Yocto* Poky image” After unzip, the folder on my machine is:

    /Users/mac/Downloads/iot-devkit-prof-dev-image-edison-20160606

  6. Finally, on a Terminal at the Yocto folder downloaded:

    ./flashall

  7. Reboot

Windows Only

  1. On an internet browser:

    https://software.intel.com/en-us/iot/hardware/edison/downloads

    QUESTION: maker.intel.com redirects to http://www.intel.com/content/www/us/en/do-it-yourself/maker.html

  2. Click “Windows* 64-bit” to download the installer:

    intel_edison_setup_win_v2016.2.007.exe

  3. In File Explorer, click to expand (unzip) the file.

  4. Double-click the file so the “Intel Edison Configuration Tool” appears.

  5. Click Next, I accept, Next, Next.

    It should go to “USB drivers installed”.

    PROTIP: If it’s stuck on “The Intel Edison is not connected”, see Troubleshooting Guide.

  6. Click Flash Firmware. Click Next to download.

    “Download the latest image version 201606061707”.

    Does this version match with the version from the board obtaind above?

  7. Click Next.

Working the Edison board

Here are operations you need to know:

Reboot interrupt serial

I reboot the Edison by unplug and re-plug everything from the board.

BLAH: This blog suggested the following to recover password. But it didn’t work for me.

  1. Reboot the Intel Edison by pressing button 6 on this diagram:

    Reset

    This says DO NOT press the Reset button due to a hardware bug.

    Pressing and holding this button for 4 seconds will restart the Intel® Edison. Alternately, pressing and holding this button for 8 seconds will reset the Intel® Edison setting all the IO pins to high impedance state with no pull-ups.

  2. When you start to see the boot up message, press any key to stop autoboot, and see this:

    boot > _
    
  3. Type:

    run do_ota

    The flashing process takes 2-3 minutes, with Edison rebooting a couple of times.

Board operating sytem

The default firmware on the Intel® Edison board is a version of Linux built using the Linux Yocto Project which started in 2010. Yocto merged with OpenEmbedded in 2011. https://www.youtube.com/watch?v=zNLYanJAQ3s

  • http://www.yoctoproject.org/docs/1.6.1/mega-manual/mega-manual.html
  • https://www.yoctoproject.org/docs/2.1/mega-manual/mega-manual.html

### Alternative OS #

Brillo is an alternative operating system from Google* based on Android that can run on the Intel® Edison board instead of the default Linux* OS built using the Yocto Project*. If you plan on using Brillo and your Brillo invitation has been approved, you do not need to run the setup tool. Instead continue to the Brillo codelab.

### View files on board #

  1. View folders and files in the present working directory:

    pwd

    The response:

    /home/root
    
  2. What version of Python is installed?

    python –version

    The response:

    Python 2.7.3
    

Development languages

  • Java Code Samples:

    https://software.intel.com/en-us/blogs/2016/07/15/20-how-to-intel-technology-code-samples-now-available-in-java

  • Even though Intel does not provide an IDE for the Python programming language, a Python interpreter comes preinstalled on the board, plus there is Python support in the sensor library:

    http://iotdk.intel.com/docs/master/upm/python/

Node-RED

Applications doing M2M (Mobile to Mobile) can be created using the drag-and-drop UI from nodered.org. The program was written in NodeJs, and export JSON blocks called the “Node-RED” visual programming language.

It’s supported by Intel, Samsung.

Brian Innes has videos “Getting started with Intel Edison and Node-RED”

Types of apps

  • Internet of Things embedded apps are mobile apps that executes on a real mobile device (such as a smart phone or tablet) interacting with users and onboard sensors on the mobile device.

    Onboard sensors on mobile devices include accelerometer, geo location, etc.

  • Web apps on a mobile device have users open a web browser and require internet access for execution on a web server. These are also called “HTML5” apps for the format of web pages displayed by web apps. These apps are invoked by specifying a URL on the web browser rather than clicking on an app icon on the mobile device.

  • Hybrid apps are called hybrid because users open such apps by downloading them from the Google Play store, but the app executes within a web app window. The Cordova library enables JavaScript to access onboard sensors. Such apps are generally slower than real apps.

Embedded apps

The code base for embedded apps consists of JavaScript which executes on a Node.js runtime on the board.

It requires an IoT maker board and is not built like mobile web apps for phones and tablets.

This approach requires these libraries:

https://software.intel.com/en-us/node/637972

This “embedded” app project does not require additional items as it blinks an on-board LED.

The steps below are an expansion of instructions here.

XDK IDE

  1. Invoke the Intel XDK program.

    It uses the Brackets Code editor described at https://software.intel.com/en-us/xdk/docs/using-the-editor-in-the-develop-tab

  2. Select “Embedded”.
  3. Select “LED Blink”.
  4. Specify a folder path

    PROTIP: Create the project under a folder for coding, such as “gits”.

    Template source code to read sensor data from:
    https://github.com/gomobile/iotapp-local-temperature

    Notice there are only a few files in a Node program.

  5. Under the XDK DEVELOP tab,

    Connect to device

  6. First, establish wi-fi to get the IP address.

  7. In XDK, for “IoT Device:”, select the IP address:



    Intel XDK - IoT App Daemon v0.1.4 - Node: 4.4.3, Arch: ia32
    
  8. Click the download icon. This should appear in XDK’s “Intel XDK IoT” tab:

    No NPM modules found.
    transferring /var/folders/j_/gh27gpxj1t58hyryfg9drvdc0000gn/T/xdk-8522mfkku4w.tar from project to board
    x README.md
    x icon.png
    x main.js
    x package.json
    x xdk/project-info.json
    Upload Complete
    Not auto starting by request
    

    A Node program includes a package.json file to define the version of Node and of each dependency library.

    The main.js file defines the logic. At the top, variables are defined, then functions called by others. The first line is usually a console.log function that prints a message out.

  9. Click the Run icon Run icon. You should see an LED on your board flashing on and off. Also this message:

    MRAA Version: v1.2.3
    

    CONGRTUALTIONS!

  10. Click the Stop icon Stop icon to stop the LED. Also this message:

    => Stopping App <=
    
  11. In main.js, notice the 1000 milliseconds (1 second) between blinks.

    Change the number to a smaller one (500) to blink less frequently.

  12. Click download icon. Click to confirm re-load.

  13. Click Debug icon to opens in a new Debugger window.
  14. Adjust the window’s size.
  15. Press F10 to step over code or F11 to step into each routine.

    Check device date

  16. Open a Terminal shell window and connect to the board.
  17. Type in command:

    date

    The response is this format:

    Sat Aug 13 12:48:57 UTC 2016

    Sync the date

  18. Click the “Manage your deamon/IoT device” icon:

  19. Select “Sync PC time w/clock on target device”.

    New System Time: Sat Aug 13 2016 12:49:25 GMT+0000 (UTC)
    

Load from internet

Instead of using XDK, do it all from the command line:

### MRAA Install #

https://github.com/intel-iot-devkit/mraa
Low level skeleton C/C++ library for IO communications on GNU/Linux platforms for (Node) JavaScript and Python.

To control more complex sensors and actuators: https://github.com/intel-iot-devkit/upm a higher-level library that leverages mara.

  1. List files where MRAA is installed:

    cd /etc/opkg
    ls -lac –time-style=long-iso

    The response I got:

    total 24
    drwxr-xr-x  2 root root 4096 2016-08-13 01:18 .
    drwxr-xr-x 89 root root 4096 2016-08-12 02:49 ..
    -rw-r--r--  1 root root   94 2016-06-07 00:51 arch.conf
    -rw-r--r--  1 root root    0 2016-06-07 00:51 base-feeds.conf
    -rw-r--r--  1 root root  277 2016-06-07 00:52 iotkit.conf
    -rw-r--r--  1 root root   60 2016-08-13 01:18 mraa-upm.conf
    -rw-r--r--  1 root root  791 2016-06-07 00:51 opkg.conf
    

    NOTE: opkg is an unofficial Linux repository which uses its base-feeds.conf file to provide access to many package, saving you the hassle of compiling from source. Some projects append additional dependencies to the bottom of the file, such as:

    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

  2. SSH onto the board to install or update MRAA on the board:

    
    echo "src mraa-upm http://iotdk.intel.com/repos/1.1/intelgalactic" > /etc/opkg/mraa-upm.conf
    

    There is no response from this.

  3. Update the library onboard and upgrade to the latest version:

    opkg update

    The response is like this:

Temp sensor on shield

Let’s look at SeeedStudio’s wiki on the Temp sensor.

Note that the Voltage is “3.3 - 5V”.

To make use of sensors, we’ll need that shield from the Grove Kit. It’s designed so we don’t have to solder anything.

  1. PROTIP: Make it a habit to discarge static before touching any electronics.

  2. PROTIP: Disconnect power to the board before you insert the Grove shield on top of the Edison board.

    The green LED should now be lit.

  3. Use the 4-pin grove cable to connect the temperature sensor to port A0 on the Grove shield.

    XDK new project

  4. If you are using XDK, create a new project file.

  5. Select Templates, Local Temperature, Continue.

  6. Specify the project name as the folder name. OK.

    Notice “Read Temperature Sensor and send temperature in degrees of Fahrenheit every 4 seconds”.

    A console.log statement sends a reading “Analog Pin (A0) Output: “ and “Fahrenheit Temperature: “ + fahrenheit_temperature);

    Edit program

  7. If four seconds (4000) is too frequent a reporting period, change it to 30000 (30 seconds).

  8. Click the download icon.

    Debugging

  9. Next, send the temperature value to a cloud for analysis and analytics.

Support Serial Numbers

For support, contact https://customercare.intel.com/?lang=en-US. For product, type in “Intel Edison” to select “Intel Edison Compute Module (IoT)”.

The form asks for the serial number from the tiny tag below the metal chip cover (such as “FZEDA 616D 01Q5B 501”).

This page shows how to get the serial number by placing the board in AP (Access Point) mode.

  1. On your board, hold down the button labeled PWR for 4 seconds (no more than 2 seconds but no longer than 7 seconds). The LED at JS2 near the center of the board should blink and remain blinking as long as your board is in AP mode.

This post offers an iotdk eclipse program to show programs to get the FPO number and ATPO number unique to each specific processor.
