Grumpy VS MicroPython

Sorta relatedly the Python to Golang system "Grumpy" seems to be moribund. I guess there's no real demand for it. Though I'm curious if there's been unpublished improvments.

Instead, I think what would be great (and maybe something I’ll get around to one day) is for someone to bring this Google project up to Python 3: https://github.com/google/grumpy

grumpy – Grumpy is a Python to Go source code transcompiler and runtime

Thank you, I’ve been looking for something more actively used than https://github.com/google/grumpy.

Reasonably, that language is MicroPython [1] which is the special pared-down version of Python for memory-constrained embedded targets.

In this post, we’ll walk through how to use MicroPython on the popular ESP8266 microcontroller to stream sensor data (like temperature and humidity) directly to a real-time web dashboard — no cloud platform, no third-party services, and no cost beyond your WiFi and coffee.

Welcome to the world of MicroPython, an efficient and lightweight implementation of Python 3 that runs directly on microcontrollers like the ESP32. This blog post is a deep dive into building a real-world smart sensor project in under 15 minutes using MicroPython – no Arduino IDE, no C++, and no nonsense.

it's not an embeddable runtime like Lua

While it's true you can't have multiple MicroPython interpreters running concurrently (or at least not easily; it's not that the design makes this impossible, it's just that all in all MicroPython is fairly young and development focus has been put elsewhere), it is possible to embed MicroPython. Not completely out of the box, needs some glue code etc. See for example https://github.com/micropython/micropython/tree/master/ports....

It's obviously not directly comparable - each port will be different - but startup time is <50ms on an RP2040 (Cortex M0 @133MHz):

Yes, although MicroPython is focused on running on microcontrollers it can be useful if you want to reduce memory consumption, flash space and even startup time on servers.

The challenge is that MicroPython has many fewer standard libraries:

And so many Python libraries targeting CPython won't work out-of-the box and you'll need to modify them or use alternatives that do work on the MicroPython subset.
