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 9600
Serial 115200

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

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

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

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/mr
aa/

Libmraa - C API
Expl: 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
EOF
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

Click on Remote System Explorer

Fill the IP address on (3)

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

Select Galileo/Edison board
You might have to restart xdk-daemon
(systemctl restart xdk-daemon)

sync host / target time if needed

Wyliodrin*

Ex: programming via cloud with www.wyliodrin.com

Please name your board and select Intel Galileo and press Next

Your SD Card is already with the Galileo Image, so all you need to do is to download (1) wyliodrin.json
and (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
