After much help from #MicroPython discussions, I finally got the #Arduino Nano RP2040 Connect working correctly. Seems that there was a corrupted disk image lurking on its flash chip. This cleared it out and made it work: https://github.com/orgs/micropython/discussions/14452#discussioncomment-9453554

Thanks for the #oshwa24 folks for including it in the swag bag!

Turning off MSC storage for the Arduino Nano RP2040 Connect · micropython · Discussion #14452

Without building a custom image, is there any way to turn off the Nano RP2040 Connect's pesky MSC storage? On a pyboard, I can add pyb.usb_mode('VCP') to boot.py. I don't see how to do this for the...

#oshwa24 folks who are having difficulties getting the wifi working on the #Arduino RP2040 connect that was in the swag bag: it has an iffy wifi firmware (1.48).

The update process is not exactly fun: https://github.com/micropython/micropython/issues/8896#issuecomment-1190050321

Home at last.

#oshwa24 was so much fun.

I should get some sleep

a recording from stuff around my desk using Darcy Neal's EMF Explorer Badge

1) USB C PD charger: typical EMF buzz kind of noise

2) Thinkpad trackpad: digital trilling

3) ESP32 microcontroller, idling: humming, ticking

@scruss jealous you're able to be involved with #oshwa24 - it was on my list of things I wanted to do this year, but there are just too many and I had to make some choices!

Je me sens vraiment nul d'avoir raté l'ouverture du sommet #oshwa24 à Montréal, je n'avais lu que distraitement les dates et day 1 et day 2 dans ma tête de linotte c'était samedi et dimanche... pas vendredi et samedi! Mais qui donc peut prendre un congé un vendredi??? j'ai plein de cours à donner moi le vendredi! Pas sûr que demain je pourrai récupérer mon sac de cossins!

Hey, there are *two* #MicroPython capable dev boards in the #oshwa24 swag bag!

- Arduino Nano RP2040 Connect

- Soldered InkPlate 2 (ESP32 / colour e-paper screen)

The green light is shining through the translucent PCB design. It's very well done indeed

(And yeah, phone chargers make all sorts of squeaks and squarks. It's amazing to be able to hear electrical noise. Wonder if I can make one of my MicroPython things play a tune in EMF on it?)
