Installing CircuitPython on a Gemma M0

(On Linux.)

[a microcontroller the size of a qyarter, plugged in to a light string wound through a blue knit cap] I wrote previously about my difficulties installing CircuitPython on an ESP32 Feather.

When I ordered the Feather, I ordered a bunch of other stuff too, including a tiny wearable microcontroller that's sold specifically for MicroPython: a Gemma M0.

Again, I had trouble getting MicroPython working, but the Gemma's problem was quite different.

Installing CircuitPython on an ESP32 Reverse Feather TFT

[A small microcontroller with a built-in display reading CO2: 470ppm and some other stuff, plugged into a USB-C cable] (On Linux, natch.)

I've been wanting to play around with CircuitPython for ages. I like Python, I like microcontrollers, what's not to like? Quite a while back, I even ordered a Feather M0 for that — but I didn't do my research, ordered the wi-fi version and it turned out that's the one Feather M0 that can't run CircuitPython.

This time I checked more carefully before ordering, and got a processor that for sure claimed to run CircuitPython.
