Does anyone have any experience beyond short programs/sketches with micropython? The most I've used it for is playing around with a microbit. How does it hold up?
If I got out a microscope and looked at cross sections of a pyboard, could an expert point out the sections of physical gates and other parts that implement each python bytecode?
MicroPython is stellar. If you're building an embedded system for people to hack and customize, make the highest level abstraction of the embedded system in MicroPython so that users can easily modify/patch/contribute/hack your system with ease. This is what Arduino and Arduino IDE did for millions of hobbyist, but it is time to ditch C/C++ for MicroPython. In this [1] PyCon talk by Matt Trentini, a demo of QR code g…
How beautiful would that be; an awesome package manager (Cargo), strong types, blazing fast bare metal performance, safe memory and less strange errors that are hard to debug in an embedded system!
Earlier quoted context omitted.
Yes, this is a complete game-changer; I love showing experienced embedded engineers how to connect to the REPL, and poke live, interactive I2C or SPI at a peripheral. :)
I only wish Micropython had a real debugger (pdb).

Still quite a lot of work left for pdb-like features but I'm optimistic it'll get there!

I'd love to try it out but the realm in which I am moving is around 32K of flash and 6K RAM. And if my research was not wrong MicroPython needs at least 256K flash and 32K RAM, and that's without any user program in Python on top of that. That's quite a lot ...

The biggest thing you are underselling (if at all), is that you can have a repl directly into the device itself and doing lots of exploratory programming directly in-circuit.
POKE
(who named these interesting commands?)
Can someone help demystify this for me? If I got out a microscope and looked at cross sections of a pyboard, could an expert point out the sections of physical gates and other parts that implement each python bytecode?

I understand what value MicroPython holds for Python community who want to get into embedded computing. But aren't these contradictory - >but it is time to ditch C/C++ for MicroPython. >Therefore, it is critical to put performance demanding code in C/C++ modules and compile a MicroPython bindings I understand that these are underlying issues of Python itself and I've been burned before because of it.

There also exists a Python-like language for when you only have a few kb of memory, and can’t even run MicroPython. It’s called “Snek”: https://sneklang.org/
That’s cool. Hadn’t seen that one. What is a “few kb”? Because last I looked Micropython was like 256kB and the smallest JS interpreter that had foreign function interface was 53kB.
From the manual:
> […] could fit on our existing Arduino Duemilanove compatible hardware. This machine has:
> 32kB of Flash
> 2kB of RAM
