11 sourcesThe Toit language and runtime is also ESP32-focused:
https://github.com/toitlang/toit
In Tactility: An ESP32 OSI also really like MicroPython! Having said that, I have been working on an alternative to it for a number of years now -- primarily to provide a more robust and performant high-level alternative to C and Rust on the ESP32-family of chips:
https://github.com/toitlang/toit
I'd love to pick your brain and fully understand your experience with MicroPython. I've been doing programming languages for a number of years now, and I find that it is incredibly useful to understand what developers appreciate (and dislike) about the available stacks.
In Rust on Espressif chips – 2023 RoadmapThank you for the mention!
I have been working on the Toit language for the ESP32 for a number of years now -- and it has been an enjoyable challenge to build an open source stack capable of supporting live reloading on a micro-controller that can run for years on batteries.

In ESP32 Buyer’s Guide: Different Chips, Firmware, SensorsFix for the UTF-8 issue on Windows is in the works: https://github.com/toitlang/toit/pull/1318.
Thanks for bringing this to our attention :)
In Running Advent of Code on a $2 microcontrollerShow HN: Micro-Services on Micro-Controllers
3 points · Open discussionWe use it for some of our tools, so it's possible (and works nicely). Our LSP server was initially written in Toit: https://github.com/toitlang/toit/tree/master/tools/lsp/serve...
(To be fair, it uses the compiler underneath for analyzing the sources).
Main restriction is, that we haven't finished the Windows implementation yet. Specifically networking and spawning processes only works on Linux/macOS so far. (The main reason we ported the LSP server to Go).
The `host` package (https://pkg.toit.io/package/github.com%2Ftoitlang%2Fpkg-host...) provides some functionality for running things on the desktop.
In Toit – A Language Designed for MicrocontrollersFunnily enough it's just a few days since I did some similar code to support writing PNGs from a small embedded device. In this case the full deflate algorithm seemed like overkill in memory and CPU requirement, and most of the images were probably going to be served over a LAN anyway.

https://github.com/toitlang/toit/commit/65c6c1bd7138f9ebced4...
It's not as highly optimized as this effort though, and it just uses the standard huffman table that is built into deflate, rather than a static-but-custom one.

In Advent of Code 2021Is it possible to compile the code at https://github.com/toitlang/toit to run on a desktop? Are there instructions on how to make such a build?
