CircuitPython Day – August 19, 2022

CircuitPython Day 2022

Friday August 19 (8/19/2022) is CircuitPython Day 2022, being designated the snakiest day this year! The day highlights all things CircuitPython and Python on Hardware.

Below is the latest on events that are developing. Firm times and additional events will be posted in subsequent posts.

Special events will be held during the day – the following is a summary of events known to date:

  • A panel discussion with Kattni, Jeff, Dan, and Tim. Hosted by Paul Cutler. More details coming soon!
  • A chat with Jeff, Dan and Kattni. This will be the third year in a row that Jeff, Dan and Kattni will sit down and chat about their involvement and latest favorite contribution to CircuitPython.
  • Special Edition CircuitPython Themed Show and Tell, hosted by Liz Clark. Details are still being solidified, but start prepping your CircuitPython related projects if you’re interested in participating!
  • CircuitPython Project Build with Maker Melissa
    Join Maker Melissa on her first ever livestream. This project will be a simple robotics project that uses the Adafruit CLUE to add Bluetooth control to the Ring:bit Buggy robotic car.

Foamyguy CircuitPython Day Game Jam Stream:

On CircuitPython Day, I’ll be combining two of my favorite things, CircuitPython and Games. I will stream the making of a CircuitPython game jam game. My goal will be to make a basic but playable and fun game within the time constraints of a few hours, and I’ll be streaming the process. After the stream, I will publish the code to the game so folks can play on their own CircuitPython devices.


11:00 AM EDT/5:00 PM CEST Reimagining IoT Deployments with CircuitPython

Adafruit’s CircuitPython has helped open up the IoT and place it within reach of developers of all types. Join blues.io on CircuitPython Day as we look at:

  • Getting Started with CircuitPython and Wireless IoT
  • Walking Through a Real World CircuitPython-based IoT Project
  • Remotely Updating CircuitPython Firmware with Cellular IoT(!?!)

New Boards Supported by CircuitPython

The number of supported microcontrollers and Single Board Computers (SBC) grows every week. This section outlines which boards have been included in CircuitPython or added to CircuitPython.org.

This week there were three new boards added!

Note: For non-Adafruit boards, please use the support forums of the board manufacturer for assistance, as Adafruit does not have the hardware to assist in troubleshooting.

Looking to add a new board to CircuitPython? It’s highly encouraged! Adafruit has four guides to help you do so:

New Learn Guides!

CircuitPython Libraries!

CircuitPython Libraries

CircuitPython support for hardware continues to grow. We are adding support for new sensors and breakouts all the time, as well as improving on the drivers we already have. As we add more libraries and update current ones, you can keep up with all the changes right here!

For the latest libraries, download the Adafruit CircuitPython Library Bundle. For the latest community contributed libraries, download the CircuitPython Community Bundle.

If you’d like to contribute, CircuitPython libraries are a great place to start. Have an idea for a new driver? File an issue on CircuitPython! Have you written a library you’d like to make available? Submit it to the CircuitPython Community Bundle. Interested in helping with current libraries? Check out the CircuitPython.org Contributing page. We’ve included open pull requests and issues from the libraries, and details about repo-level issues that need to be addressed. We have a guide on contributing to CircuitPython with Git and GitHub if you need help getting started. You can also find us in the #circuitpython channels on the Adafruit Discord.

You can check out this list of all the Adafruit CircuitPython libraries and drivers available.

The current number of Adafruit and community contributed CircuitPython libraries is 360!

New Libraries!

Here’s this week’s new CircuitPython libraries:

What’s the team up to this week?

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

Dan

This past week I debugged some ESP32SPI-related problems, which were due to MQTT timeouts and not handling certain exceptions. I revised a number of Learn Guide projects to fix these potential issues.

I’ve now gone back to working on the ESP32 port, and am currently debugging builds for boards with no PSRAM available.

Jeff

I handed back the ESP32 port to Dan so that I could finish up a guide called Using QMK on RP2040 Microcontrollers. When I returned to CircuitPython land, I started working on some updates to the camera support on Espressif microcontrollers that has since turned into a full rewrite. We hope that when it’s done, we’ll be able to use a wider range of cameras on ESP32, ESP32-S2 and ESP32-S3 boards with a new API.

Kattni

This was another short week for me. I focused on getting the final WipperSnapper pages completed. Other than that, I finished up a bunch of miscellaneous items I had hanging around or recently assigned.

In CircuitPython Day news, I’m continuing to add more content. Next week I’ll be spending more time on planning, and I’m hoping to have a tentative schedule available soon! Keep an eye on it here.

Melissa

This past week, I’ve spent most of my time working on refactoring code.circuitpython.org in order to accommodate additional workflows. Part of it was re-familiarizing myself with the existing code and then coming up with a plan about how it should work and the steps I needed to get there. Once that was figured out, the refactoring itself was relatively quick. While the interface is still almost exactly the same at this point, the underlying code structure is now quite a bit better and more loosely coupled.

Tim

This week I continued working on the Octopus game guide and adding comments to the code for it. I believe the game is now set save for some smaller details like potentially highscore saving. I’ve also still been working on the Hack Tablet build of CircuitPython that is adding dot clock display support for displayio. The giveaway for these tablets was officially announced this week and entry form is available now for those that wish to enter for a chance to receive one.

Scott

This week I’ve been improving the web workflow. I’ve just about finished adding dynamic reconfig and changing the port. I improved the responsiveness of the workflow so that it responds as other code is running. I’ve tweaked the C3’s serial transmit code to improve reliability. Currently, I’m reworking the status title bar code so that it is only transmitted as needed and therefore, speeds everything up.

Liz

This week I wrapped up the IoT Pet Food Scale using CircuitPython with Microsoft Azure. I also made a 1-minute video about the project featuring one of the benefactors of the project: my cat Winnie.

I also worked on documenting the new 9-DoF sensor in the shop: the LSM6DS3TR-C + LIS3MDL Stemma Breakout. I wrote up a standalone guide for it, added it to the ST 9-DoF Combo Breakouts guide and went through the How to Fuse Motion Sensor Data into AHRS Orientation guide to make sure magnetometer calibration was working as expected.
