lvgl VS slint

So here is the thing: The iPod Nano 7g is from 2012. I've seen many people designing custom PCBs and releasing Kickstarter projects for custom audio players[5] or game handhelds[6]. I know Rockbox (which is great, but its lacks support for Wifi and Bluetooth AFAIK and just does not compete with the UX of iPod's audio book features in my opinion) and iPod Linux. 10 years ago someone even reverse engineered the iPod Nano 6g display[3].

Although I'm not skilled enough in PCB-Design, after some research I found the Lilygo T-Display S3 Pro[4] based on ESP32 S3, which would be the size, but lacks audio and OS. There is also the Mango PI CyberPad[7], which looked interesting, but maybe is already too clunky.

Programming wise, LVGL[8] may be a good framework to develop a modern and efficient UI - at least it looks promising.

So, why is nobody interested in recreating an iPod nano like device? It should be doable with modern tech, but Phones have completely taken over the marked...

LVGL is a graphics library used mostly for embedded UI's. Main website: https://lvgl.io/

Popular embedded UI library

If you need something written in C and very tiny, I recommend LVGL https://lvgl.io/

The factory code uses the Lvgl graphic library. https://github.com/lvgl/lvgl

I'm trying to interface SPI LCD (ILI943) with Zynq 7020 (PYNQ-Z2 board) and LVGL embedded UI libary. And considering between two approaches:

Did you get a chance to check https://slint.dev?

Disclaimer: I work for Slint

Currently, we do it by using binaries through napi-rs so we can bring in a window using the platform native API. And then we do some hack to merge the event loops.

But if Deno supports bringing up a window directly, this means we can just ship wasm instead of native binary for all platform. And also I hope event loop integration will be simplified.

Although we'd also need more API than just showing a window (mouse and keyboard input, accessibility, popup window, system tray, ...)

Thanks for reporting the broken link. Fixed in https://github.com/slint-ui/slint/commit/9200480b532f49007d2...

With Slint (https://slint.dev) we're trying to make a lightweight toolkit that doesn't use HTML/CSS. And that you can program either from low level languages such as C++ or Rust. As well as with higher level language such as JavaScript, and we want to extend to python too.

I haven't. I was just searching for a GUI library that was Bevy-compatible and slint isn't at the moment: https://github.com/slint-ui/slint/discussions/940

Sorry!

Trying to do that with Slint: https://slint.dev

You can do that with Slint (https://slint.dev) and its linuxkms backend. No need for a xorg server or wayland compositor, just run the application made with Slint from the init script.
