The Tutorials Wiki contains guides on a variety of Omega topics, from the basics of Linux, to how to use the Omega Expansions, to using specific software or accomplishing a certain task.

Connecting to the Omega

The wiki is moving! These articles can be found in the Onion Docs already, and will be updated there.

Taking the first step, connecting to the Omega's command line:

Introduction to Linux

This series of tutorials is meant to get you comfortable with using a Linux environment:

Introduction to OpenWRT

This mini-series is meant to introduce users to OpenWRT.

In case your Omega's firmware gets corrupted during installation, it is possible to reflash a fresh firmware:

Using the Docks and Expansions

The wiki is moving! These articles can be found in the Onion Docs already, and will be updated there. (* - denotes articles that do not yet exist in the Onion Docs as of time of writing)

The Omega's functionality can be greatly extended with the different available Docks and Expansions.

The Omega itself has an LED onboard, it can be controlled to blink in a variety of patterns:

The Expansion Dock

The Expansion Dock provides a breakout for the Omega's GPIOs, allowing you to use the Expansions or simply drive the GPIOs. It also has an RGB LED that can be programmed to show different colours:

The Power Dock

The Power Dock also provides a breakout for the Omega's GPIOs, allowing you to use the Expansions or drive the GPIOs. However, the Power Dock can also be powered by just a battery, and has battery management to intelligently charge the connected battery:

The Expansions

The Expansions provide additional functionality and features to the Omega:

The Arduino Dock

The Arduino Dock has an ATmega microcontroller and can be used just like an Arduino:

The Bluetooth Low Energy Expansion *

The BLE Expansion can be used to add Bluetooth connectivity to the Omega:

The Camera Kit *

The Camera Kit includes a 720p webcam and a pan & tilt servo mount. Assembly instructions are below:

LAMP Stack

PHP

NodeJS

We've added support for installing a few Node modules via opkg:

Reading Sensor Data

The Omega can be used with a variety of different communication protocols. I2C is supported out of the box, for others, additional work is required:

The Omega supports Ubidots, a third-party data visualization service:

Cross Compilation

The Omega can run C and C++ programs, however, it does not host a C compiler, so these programs will have to be cross-compiled on another machine and then installed on your Omega:
