Embedded devices running lv_binding_js(lvgljs)

[Wvirgil123]

Hello, lv_binding_js is a great feature. We are considering whether it can be run on esp32, which will greatly facilitate UI development.
I would like to ask:

1. What devices has lv_binding_js been run on so far?
2. What are the limitations or difficulties of porting lvgljs to embedded devices (such as esp32)? Is there a minimum performance or resource specification?

Hello,

I can’t tell you what devices it has been run on, the Github page for the lvgl binding has no mention of embedded devices except for embedded Linux: lv_binding_js/doc/build/build-device.md at master · lvgl/lv_binding_js · GitHub

It would seem to me quite difficult to port something written in Javascript to the esp32. Why not just write it in C? LVGL uses many concepts from JS already.

Allowing JavaScript would make it much easier for web developers to get started with embedded devices. Some Fitbit devices allow creating third party apps and clock faces using JavaScript, CSS, and SVG. I would like to be able to do something similar.

High level declarative UI framework for i.MX RT Crossover MCUs

Are there any high level declarative UI frameworks for i.MX RT Crossover MCUs? I would like to be able to write code in a high level language like Swift or JavaScript and create the UI using something similar to SwiftUI or React. I really like the idea of lvgljs, but it currently only supports Linux.

Microcontroller support for lvgljs

It would be helpful to have a version of lvgljs that can run on microcontrollers without Linux. This would make it much easier for web developers to get started with embedded devices.

Bounty for JavaScript support on TDeck

Hi, fantastic library. I hope it’s ok but I’m offering a bounty for a proof of concept of LV Binding JS running on the lilygo tdeck.

TDeck support bounty

There was a bounty for JavaScript support on TDeck but it doesn’t look like it was ever completed.
