I made something working for the micro bit
I've published it there :
https://github.com/titimoby/microbit4al ... rix7219.py

If it's better, I can push a PR to Radomir's repository

Re: MAX7219 on micro:bit

I had several issues here. One was the way to call SPI because I mixed doc from a lib for microbit and one from adafruit (but from deshipu ion the end ;) ) I used the library : https://github.com/adafruit/micropython-adafruit-max7219 That I needed to edit to replace low() and high() calls with off()...

Re: MAX7219 on micro:bit

As soon as I can flash a micro:bit I'll give a try. In the meantime, I tried with a Wemos D1 Pro flashed with micropython. I got the following result when I try to get the Spi part : >>> import max7219 >>> from machine import Pin, SPI >>> spi = SPI(10000000, miso=Pin(12), mosi=Pin(13), sck=Pin(14)) ...

Re: [Numworks] more than a board.

I received mine yesterday ;)
I also have compiled the simulator and a local firmware and will try to flash it.

[Numworks] more than a board.

A new calculator brand just appeared and they have Micropython embedded : Numworks For the moment, it looks minimal but as they share everything from hardware schematics to code, it will be interesting to follow their progress.

Re: Reference design released

I don't have enough knowledge in that area, but on the micro:bit community Slack, a discussion just said all files are here.
