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.
