Why Lua Beats MicroPython for Serious Embedded Devs
｢ Lua isn’t just compatible with embedded systems; the Lua ANSI C library was designed for them. Its architecture is clean, compact, and deterministic.
MicroPython, on the other hand, is a reimplementation of Python 3. It works well for many embedded use cases, but it inherits assumptions from a desktop-oriented language ｣

I just published a #micropython #mqtt server and #python client for accessing a remote filesystem on a micropython device by mqtt.
See:
https://github.com/dov/upython-mqtt-file-server
Meanwhile I have used it for uploading photos to my #pimoroni #presto device.
This library solves the "grandma problem" of how to place a photo frame on grandma's mantle piece and push images to it without her interaction.
I am a sucker for opto-electronics, so got this discarded kit (ex CNN's London studio?)
Each button has a 36x24 LCD display and red+green LEDS.
Well-designed hardware: ColdFire (=68k) CPU, plenty of RAM, plenty of FLASH, serial port, ethernet etc.
Firmware ? Not so impressive, but very easy to get rid of:
Anybody can flash new firmware from ethernet: No userid, no password, all you need to know is the IP# and how they botched their CRC-16 implementation.
Now it runs #MicroPython :-)
My latest blog post: Metronalmost

This metronome, by design, will never, ever, tick exactly once per second. This infuriating object is designed to thwart the goals of @hackaday's One Hertz Challenge contest.
I went ahead and created a github organization for a fresh fork of micropython, and then made a release. You can get a fresh dsk of this micropython mac port from https://github.com/m68k-micropython/micropython/releases and as @smallsco noted it works on infinitemac.org
Doing a little iterative code development in micropython on an emulated m68k mac... I might not be so happy with the loading time if a real floppy was involved, but in an emulator it's heckin' snappy.
Clearly I need to tackle the issue that you can't REALLY draw to the same window as the terminal....
Now you can witness one of the first quickdraw calls from MicroPython on mac... 
how it started: "let's try to get started on a set for my #RFFF25 gig"
how it's going: "attempting (and so far failing) to completely rewrite some 2-year-old #MicroPython code on my DIY MIDI to CV interface"

and in case you want to use #MicroPython on this thing:

Is there anyone in the room with knowledge about #ESP32 microcontrollers?
I am playing with a #Waveshare development board that has an #AMOLED and a touchscreen, and it says it has built-in #SH8601 display driver and #FT3168 capacitive touch chip, using #QSPI and #I2C communication respectively.
https://www.waveshare.com/product/arduino/boards-kits/esp32-s3-touch-amoled-1.8.htm
It directly works in #Arduino with #C, but I am trying to make it work with #MicroPython.
Before I spend effort trying to compile it with #LVGL, I want to know if I could print a "Hello World" to the screen as is, and while my mind tells me that I need a driver, the sentence "built-in display driver using QSPI" makes me think that I could eventually use the display without code drivers, but I don't know how.
I'd love to see an example, if it's possible, or to be pointed to any resources that I can read in this regard. I am complete newbie.
Re-posts are appreciated.
Thank in advance 
asyncio is working on mac micropython!
also (not shown here) the "sys.stdin" object is pollable, and you can double-click a python file to run it as the main code file.
Let's-a-go!
Are there any folks with vintage Mac programming experience who'd like to collaborate on figuring out what's next with Micropython on Mac?
I think that might be: What's the minimal set of APIs to do a fun graphical demo.
Pointers to "how to"-ish documentation in Pascal and C would be great as well, I have failed at finding this kind of stuff. (I do have Inside Macintosh but it is not a great tutorial)
oh my yay, it now works well enough to save and edit a file, then import and run that file.
you could basically use an old m68k mac as a python3 (well, micropython) development system now.
don't mind the debug messages, they're as scared of you as you are of them.
Whee! Now we can import files from the filesystem, as well as reading and writing files. Still haven't wrapped my head around how folders work, still can't enumerate files ..
as usual, work pushed to my micropython fork on github (which is called circuitpython, because you can't have two different forks of the "same" original project, argh).
Darn, I think all the easy parts of the micropython mac m68k port are done.
unfortunately, vfs_posix doesn't seem to be a good fit. I did manage to create a "file" but couldn't actually write data to it.
And while it was working in system6 I just tried it again with system7 and it's failing to start at all. boo.
https://github.com/jepler/circuitpython/blob/ports-m68kmac/ports/m68kmac/README.md#key-todos
Build updated at https://emergent.unpythonic.net/files/sandbox/micropython.dsk
Almost all of the "full features" support level of micropython are enabled, "mpz" for long integers and "float" for floating point numbers.
Backspace works in the repl. arrow keys don't.
A TODO section in the new README lists key items to work on:
Social media loves graphs right?
Logging humidity, temperature and battery voltage with my custom ESP32 board is working nicely. Guess where in the graph I switched from USB to battery power. #esp32 #electronics #grafana #micropython
Micropython on m68k mac? why not! It's reached the point of sorta working.
The June MicroPython Meetup is tomorrow!
https://www.meetup.com/micropython-meetup/events/306214020
Hope to see you there, or online.
[And, if the stars align, we may also have a demo of debugging MicroPython with VS Code!]
