LVGL Quickstart Template

Hi everyone!

We’re back with another update!

LittleVGL Template

To make GUI development for the Omega2 Dash quick and easy, we’ve designed the Omega2 Dash to be compatible with the LittleV Graphics Library. LittlevGL (lvgl) is a free and open-source graphics library that has everything you need to create an embedded GUI with easy-to-use graphical elements and visual effects.

Last update, we showed you the lvgl "kitchen sink" demo running on the Omega2 Dash. It’s an example UI that shows off a whole bunch of the available graphical elements and themes to give you an idea of what’s possible.

This update, we’re sharing our lvgl template! It’s a pre-configured lvgl C project that supports drawing to the Omega2 Dash display and reading touch input. It also includes a makefile and instructions to build it as an OpenWRT Linux package.

You can use this template as a time-saving starting point for building your own UI for the Omega2 Dash! We’ve added ~10 lines of demo code that draws a button and executes a callback whenever it’s pressed. Start there and build your own amazing UI.

The Omega2 Dash lvgl template can be found on on GitHub, along with instructions on how to test drive it on your own Omega2 Dash.

Omega2 Dash

An Omega2 Dash IoT computer. Perfect for making internet-connected control panels and user interfaces.


Ethernet Expansion

From the Onion Omega2 Pro project.

An Ethernet Expansion board for your Omega2 Dash

The Ethernet Expansion adds an Ethernet port to your Omega with a maximum connection speed of 100Mbps. While the Omega is all about wireless connectivity, a reliable wired network connection can be a great addition to a project, and the Ethernet Expansion is a great tool for quickly reflashing your Omega’s firmware.


NFC/RFID Expansion

From the Onion Omega2 Pro project.

An NFC/RFID Expansion board for your Omega2 Dash

Bring contact-less RFID and NFC communication to your Omega2. It supports reading and writing with several NFC and RFID protocols at 13.56 MHz. Comes bundled with two programmable Mifare Ultralight tags.


ADC Expansion

From the Onion Omega2 Pro project.

An ADC Expansion board for your Omega2 Dash

Omega2 can now read all types of analog voltages and sensors with the help of this ADC Expansion. Read and interpret up to 4 analog voltage or sensor inputs, each with 16 bits of precision.


Proto Expansion

From the Onion Omega2 Pro project.

A Proto Expansion board for your Omega2 Dash

The Proto Expansion for the Onion Omega allows you to create your very own expansion that interfaces with your Omega. It provides a small soldering area and 30-pin header that plugs into the Expansion Dock. With it you will have full control over what kind of project you design for your Omega.


Servo Expansion

From the Onion Omega2 Pro project.

A Servo Expansion board for your Omega2 Dash

The Servo Expansion adds 16 PWM (Pulse Width Modulation) outputs to your Omega. Connect standard servos directly to the Expansion since each channel has its own 3-pin connectors, making it that much easier to get started with your project! This Expansion is great in any application that requires servos, like a robotics project or anything with moving parts. Given that PWM is so useful, you can also use this Expansion to precisely control LEDs or drive a DC motor using an H-bridge. The Servo Expansion is often also called the PWM Expansion.
