Setting up the developer environment

Now connect your environment

Intel® Galileo / Intel® Edison

For Windows*: first install driver from USB stick

Ref.: https://communities.intel.com/docs/DOC-23147

Serial 115200

Serial 9600

Connect board via serial – discover port (Windows*)

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

Connect via serial e.g. using PuTTy*, goSerial* or minicom* resp

User: root, no password* Other names and brands may be claimed as the property of others.

Connecting Intel(R) Galileo

Wifi

connmanctl, rfkill, wpa_cli, hostapd_cli

Bluetooth

connmanctl, rfkill, bluetoothctl, hciconfig, hcidump, btmon

serial

Connecting Intel(R) Edison

On Windows* - first install driver from USB stick

“configure_edison --setup”

• One central way to set hostname, password and configure wifi

Wifi

connmanctl, rfkill, wpa_cli, hostapd_cli

Bluetooth

connmanctl, rfkill, bluetoothctl, hciconfig, hcidump, btmon

Eth over USB

serial


Find your Galileo/Edison IP address and write it down: command `ip a`

Ping between board and your laptop to check

connectivity


Programming

Arduino* IDE for Intel® Edison

Recap – navigating IDZ IoT - https://software.intel.com/iot

libmraa & UPM

libmraa - https://github.com/intel-iot-devkit/mraa

IO abstraction layer (C, C++, Python, Node.JS)

Used by

• UPM

• Intel(R) XDK for IoT

• Wyliodrin*

API documentation http://iotdk.intel.com/docs/master/mraa/


Libmraa - C APIExpl: switch on GPIO #8

mraa_gpio_context gpio; // Pointer to GPIO context

gpio = mraa_gpio_init(8); // Create GPIO context for pin 8

mraa_gpio_dir(gpio, MRAA_GPIO_OUT); // GPIO direction: out

mraa_gpio_write(gpio, 1); // Write to GPIO

mraa_gpio_close(gpio); // Close GPIO

Libmraa - C++Expl: read analogue value on A0

mraa::Aio* a0;

a0 = new mraa::Aio(0); // Create AIO object for pin 0

std::cout << a0->read() << std::endl;

Libmraa – Object API (Python)Expl: interrupt triggered on IO #6

from mraa import * # Import mraa library

# define a callback function

def my_isr():

print("Button pressed")

x = Gpio(6) # Create a GPIO object for pin 6

x.dir(DIR_IN) # Set GPIO direction to input

x.isr(EDGE_BOTH, my_isr) # Set callback on BOTH

Libmraa – Object API (Node.js)Expl: did we have this? – switch on IO #8

var m = require("mraa") # Import mraa module

var x = new m.Gpio(8) # Create a GPIO object for pin 8

x.dir(m.DIR_OUT) # Set GPIO direction to output

x.write(1) # Write to 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

C++ example:

// Copyright (c) 2014 Intel Corporation. MIT license

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);

}

UPM API documentation – which library to use?

Updating libmraa / UPM

cat > /etc/opkg/mraa-upm.conf <<EOF

src mraa-upm http://iotdk.intel.com/repos/1.1/intelgalactic

opkg update

opkg upgrade

Eclipse* IDE


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


http://www.7-zip.org/

Click on Remote System Explorer


Fill the IP address on (3)


Intel(r) XDK for IoT

Login/create your account

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

Should look like this

Select Galileo/Edison board

You might have to restart xdk-

daemon (systemctl restart xdk-

daemon)

Toggle the console

sync host / target time if needed

Install / build

Upload to target

run on target

Wyliodrin*


Ex: programming via cloud with www.wyliodrin.com

Please name your board and select Intel Galileo and press Next

Cable (Ethernet) WiFi

Your SD Card is already with the Galileo Image, so all you need to do is to download (1) wyliodrin.jsonand (2) write it on the root of the SD Card. Make sure the name is exactly wyliodrin.json

Install the updates and the extra libraries. This make take some time to run
