Arduino IDE
Before you start
Update Galileo Firmware• Download latest IDE from
http://arduino.cc/en/main/software
• Extract the content to a folder
• Power up the board and then (then only) connect the
USB to USB client
• Open Arduino IDE
• Go to Help and click on Firmware Update
Be Patient, it might take sometime. It might even disconnect itself from your computer.
DONT UNPLUG THE cable.It might take time but works!!!
Boot the Development Environment
Use PuTTy to connect to the board and execute
commands.
You can use WinSCP to transfer files to the board.

Software Tools
Developer Kit C++ Tools
• One IDE for all three supported boards
• Ready to run sample code
• SSH Connection to developer board for remote GBD server.
• Eclipse tools also work for Arduino Sketch code build and debug
Developer Kit JavaScript Tools
• mraa – open source library for Galileo/Edison used API similar to the *MBED api (Intel Iot Devkit )
• io-js- open source library for Galileo/Edison used API similar to the Arduino API (Intel Labs China )
• johnny-five – Open source I/O library with plugins for various boards including Galileo (Gen2 demo upstairs)
• on/off – open source i/o library that can be used to manipulate ‘raw’ GPIO/PWM via sysfs interface
• i2c – node.js i2c library (uses sysfs)
•
JavaScript I/O Libraries for Galileo
Developer Kit Python Tools
There is one IDE for Intel® Galileo board. Works with Generation 1 and 2.
GUI based online python development from Wyliodrin
Wyliodrin agent pre-installed in IoTdevkit SD image.
(Galileo only for now)
It’s Show Time
Intel® GalileoNetwork Setup
Enable WiFi
Hardware setup:
1. Connect the board through FTDI cable or through Ethernet cable.
2. Connect Intel Centrio N135 wifi card to PCi slot
We use connection manager “connman” in DevKit

Overview of “libmraa” and
“libupm”
Libmraa
• Defines the capabilities of GPIO pins,
Autodetection of Gen 1, Gen 2 and Edison DVT
Libupm
• Defines the interaction of high level sensors.
• Buttons, Buzzers, LCD, LED, Light Sensor, Servos, Rotary Angle Sensor, Relays, Sound Sensors, temperature sensors … more are added continually.
Purpose of Each Library
Using libmraa for the Blinky Light Demo
