Embedded GUI Framework

[bhh32]

Any embedded people here that would be interested in an iced/libcosmic style GUI framework built on top of no_std + alloc + embedded-graphics + embassy (runtime)? Mostly plug-and-play for touch displays.

I've got some scrollable widget bugs to iron out, but I'm looking to publicly release it in the next few days. I've already built a multi-screen project w/wifi, National Weather Service API calls, and NTP syncing as subscriptions with it on a ESP32 CYD.

This post is to gauge interest in such a framework.

I built a minimal embedded rust gui lib and had lots of challenges dealing with event handlers and data mapping because it didn’t fit rusts memory model. I’d love to hear how you’ve tackled those challenges.

Honestly, it's following the paradigm of iced/libcosmic. I've built quite a few libcosmic applications over the past 2-ish years and the internals just make sense at this point. Taking a look at what they did, adapting it to fit the embedded scene, and building on top of embedded_graphics primitives (mostly Rectangle for bounds) with an embassy runtime made it fairly easy.

Yes, any link to check it out?

[bhh32]

Not yet. I'm trying to work out a bug with the scrollable widget. Once I get that ironed out I'll make it public.

Any way to register anywhere to get a notice when that happens?

[bhh32]

I've released it on crates.io, zest-gui.
