Official Rust binding, LVGL and SLS releases, DASQI and Elecrow board certifications and more
This is the copy of the monthly newsletter sent out to our subscribers.
I have a lot of exciting things to share with you this month. So let’s dive right in!
Official Rust binding
In the previous newsletter, I mentioned “lvgl-rs,” an unofficial Rust binding for LVGL. I’m thrilled to announce that it has now become official! 🎉 You can find it in the lvgl/lv_binding_rust repository. I believe the possibility of creating embedded UIs in Rust will captivate many.
Furthermore, I’d like to express my gratitude to Nia, the new maintainer of this repository, for their outstanding work!
A new patch version of LVGL has been released with several bug fixes. For more details, refer to the changelog.
We have also launched a new version of SquareLine Studio. The major new features include:
- Multilanguage support
- Organizing exported files into folders
- Exporting CMakeFile.txt and a general filelist for easier integration
- Ability to send crash logs
You can find the complete list of new features and fixes here.
DASQI board certification
DASQI Apollo4B is a powerful board specifically designed for smartwatch applications. With a wide range of sensors and an impressive display, it is the perfect choice for developers aiming to create cutting-edge wearables.
Elecrow board certification
Elecrow’s ESP Terminal 3.5” board is fantastic, featuring the powerful ESP32-S3 chip with a dual-core processor running at 240MHz. Its Octo-SPI technology enables fast and efficient access to both flash memory and RAM.
Presentation at RT-Thread conference
In June, I will be giving a presentation on the new version of SquareLine Studio at the RT-Thread Global Tech Conference. It will be the first event where we showcase the completely revamped version of our editor. You can register for the conference here
By the way, among the participants, we will be drawing five RT-Thread - Renesas boards. So it’s definitely worth registering! For more information about the board, check here.
Migrate to RST documentation
We use Sphinx as a documentation engine and its native file format is “reStructuredText” (RST). Thanks to the amazing work of Kevin Schlosser, we now have our entire documentation in RST instead of Markdown. This allows us to leverage the full power of Sphinx, including more cross-links within the documentation and a better API summary. Take a look at the documentation of the Arc widget as an example. You’ll find that all functions and constants are now hyperlinked!
By the way, Kevin is currently developing a Python3 binding for LVGL. I will keep you informed and let you know when it’s ready for you to try out.
FreeType on ESP
100ask just created something incredibly useful again: they have been released a FreeType-LVGL component for ESP32. With this component, you can now generate fonts at runtime directly from TTF or OTF files.
And that’s all for now. I’ll be back in a month with more updates. Stay tuned! 🙂
