Important – before starting
• The next session can save you a lot of time and trouble – which will count tomorrow
when you are trying to finish your project
• We will cover step by step how to get started
• Your options:
• C/C++ with Eclipse (recommended)
• JavaScript with XDK (recommended)
• Arduino (recommended)
• Visual programming with Wyliodrin – if you are new to programming
• Vi/terminal – if you are more comfortable with command line environment

Setup the Galileo board
Distributed micro SD cards already prepared with latest image – just plug them in
Why do we need a micro SD and an image?
- Provide easy way to permanently store application on board
- Provides extra libraries and bindings
- Supports multiple programming languages
Note: For future updates, please refer to online documentation.
Ref.: https://software.intel.com/en-us/iot-c-eclipse , Appendix

Setup the Edison board
Distributed Edison already updated
If not, update software: https://communities.intel.com/docs/DOC-23192

Setting up the developer environment

Connect the SD card in your computer – copy the IDE
file correspondent to your OS; for Windows, copy win-driver
too

Windows & Arduino – extract and install the contents of win-driver

Now connect your environment
microUSB <-> USB
Ref.: https://communities.intel.com/docs/DOC-23147

Now connect your environment
USB <-> Serial cable
Ethernet
Power
SD Card
Serial

Ref.: https://software.intel.com/en-us/iot-c-eclipse

USB-Serial on Gen2 – black wire means ground

Connect board via serial – discover port on Windows

Connect board via serial – discover port on MacOS
After connecting the serial cable, check if you have /dev/cu.usbserial(*)
If not, you may need to install a serial-USB FTDI driver.
Example:

Connect via serial – putty, goSerial or minicom
User: root, no password

Connecting Edison – configure_edison --setup
Configure password
Configure wifi
Galileo should automatically set up an IP address.

Find your Galileo/Edison IP address and write it down:
command `ip a`
Ping between board and your laptop to
check connectivity

Shortcut – if you feel comfortable with vi
If you have experience coding directly from the command line, you have:
• Busybox/vi
• Gcc
• Python
• Node.js
But we will continue with the IDEs, keep paying attention 
Vim: https://github.com/IntelOpenDesign/MakerNode/tree/master/iotkd_libs

Time to chose your path:
C/C++:
• Eclipse
Javascript:
• XDK
Arduino
• Arduino IDE for Galileo
Visual Programming (Blocky)
• Wyliodrin

Arduino for Galileo or Edison
https://communities.intel.com/docs/DOC-23242

Eclipse(C/C++) – setting up
Copy to your computer
Extract the file you copied previously (iotdk-ide-${yourOS}.7z) with 7z
 Treats long paths better, needed for this file.
 If you need to download: http://www.7-zip.org/
Note: Better to extract the file to C: on Windows
Execute devkit-launcher.bat

Click on Remote System Explorer

Fill the IP address on (3)

Running a sample - Click back on C/C++
Ref.: https://software.intel.com/en-us/node/519969

Galileo - Right click 4_cpp_onboard_led

Click Run, select 4_cpp_onboard_led

Install the file copied from the SD card, XDK directory
Ref.: https://software.intel.com/en-us/html5/xdk-iot

Start with a Sample (under IoT Projects) – click on “Use this
Template”

Click Manage your daemon/IoT device menu in the bottom
taskbar. Select sync PC time w/ clock on target board to
avoid computer and device timing issues.

Click Install/Build to fetch node modules specified in
package.json and install them on device; 1st time click Build

Click Upload to upload the current project to the Galileo
board

Click Run to run the project on the device. The LED should
be blinking.

Devkit library (MRAA) and sensor repository (UPM)

MRAA lib - https://github.com/intel-iot-devkit/mraa
MRAA – random letters, doesn’t mean anything
API documentation available - http://iotdk.intel.com/docs/master/mraa/
Examples directory
Minimum code sample:
mraa_gpio_context gpio;
gpio = mraa_gpio_init(6);
mraa_gpio_dir(gpio, MRAA_GPIO_IN);
for (;;) {
fprintf(stdout, "Gpio is %dn", mraa_gpio_read(gpio));
sleep(1);
}
mraa_gpio_close(gpio);

UPM repository - https://github.com/intel-iot-devkit/upm
List of supported sensors in C++
API documentation - http://iotdk.intel.com/docs/master/upm/
Examples directory
Minimum code example:
upm::GroveTemp* s = new upm::GroveTemp(0);
std::cout << s->name() << std::endl;
for (int i=0; i < 10; i++) {
std::cout << s->value() << std::endl;
sleep(1);
}

Just remember to use the correspondent library
Project name (right click)
-> Settings -> C/C++
Build -> Settings -> Tool
Settings -> Cross G++
Linker -> Miscelaneous

UPM API documentation – which library to use?

Create your first app – copy&paste an existing sample

Creating your first app – if you use UPM repository
Project name (right click)
-> Settings -> C/C++
Build -> Settings -> Tool
Settings -> Cross G++
Linker -> Miscelaneous

Node.js
Find the library name – example: libupm-grove
-> replace “lib” for “js” and you have it: jsupm_grove
Code:
require(“jsupm_grove”);

Python
Find the library name – example: libupm-grove
-> replace “lib” for “py” and you have it: pyupm-grove
Code:
import pyupm_grove

Go to IDZ IoT page, find your sensor
