Welcome to the latest Python on Microcontrollers newsletter! Folks are sending in their feedback on where CircuitPython should go this year. You still have time to do the same. CircuitPython 9 is getting closer to a beta release along with major image and video handling capabilities. Raspberry Pi 5 still dominates much of the news as people get them and either put them to work or add new accessories. And much more news including a blast from the past robot from Arduino. – Anne Barela, Ed.

UVC Video Coming to CircuitPython 9

UVC Video

TinyUSB, the USB driver used by CircuitPython, has recently added UVC support. UVC is a USB device class that describes devices capable of streaming video like webcams, digital camcorders, analog video converters and still-image cameras. Jeff Epler has been doing preliminary work to integrate UVC into CircuitPython 9 so devices can act as webcams, for example – YouTube and pull request GitHub.

What’s the CircuitPython team up to this week?

What is the team up to this week? Let’s check in:

Dan

This past week Scott and I did some pair debugging and were able to fix a longstanding issue that made some operations not work correctly when you subclassed the built-in dict type.

A user encountered another core language problem. I found it was already reported to MicroPython, and is not easy to fix without possibly causing an mpy version change, so we’ll await a fix from upstream.

Melissa

This past week, I’ve been working on getting the PiTFT displays working on the Raspberry Pi 5 with Bookworm. So far, the 2.2” PiTFT has been updated and works. I’m still struggling with getting the touch rotation to work for the 2.8” capacitive and resistive touchscreens, but hopefully that will be worked out soon.

Tim

This week I’ve been working on the 1D Chomper game and Learn Guide. I did a load of cleaning up and commenting the code. I also set up the light box to take some clean photos for the guide and recorded a quick look introduction video for the project.

Jeff

With bitmapfilter merged into the “absolute latest” CircuitPython builds, I’m concentrating on something new: support for CircuitPython operating as a “UVC” device, which lets CircuitPython appear like a webcam to a host computer. Ultimately, the intent is to make this work with displayio applications, so that in addition to displaying to an LCD or similar display attached to the microcontroller, they can display on a host computer.

Scott

This past week has been co-opted by a daycare flu. Ari got it and then I got it a few days later. So, I haven’t done as much as I would have liked. My main work is accessing the SD card over WiFi and BLE. The PR is ready and will hopefully get merged in the next few days. Next, I’m finishing up my #CircuitPython2024 post. After that, I’ll be heads down on bug fixing for the 9.0 release. I’d love to get 9.0.0 released in February (just like 8.0.0 was released last February.)

Liz

This week I published the Qualia S3 Compass project. I used a Qualia S3 with a 2.1 inch round display and a 9-DoF sensor to create a working compass. I learned a lot working on this project, since first of all I had never really used a compass, but there was a lot of math involved in calculating the compass heading properly and displaying it in two different ways on the round display. I’d like to extend a hug report to community member Gamblor21, whose AHRS CircuitPython library in the community bundle was extremely helpful for this project. I also used rotozoom from the built-in bitmaptools for the first time and once I understood how to use it properly, it was a game changer. I look forward to using it in future projects.
