CircuitPython 4.0.0 Release!

CircuitPython 4.0.0 Released

4.0.0 is the latest major revision of CircuitPython and a new stable release! Download it now from circuitpython.org. See here for the full release notes.

It features a port to the Nordic nRF52840 microcontroller, including support as a BLE beacon or peripheral (bleio), extensive new support for pixel-based displays (displayio – guide here), which will show CircuitPython output on the display, USB MIDI support and messages translated into multiple languages. Current languages are Chinese (Pinyin), English, Tagalog (Filipino), French, German, Indonesian, Italian, Polish, and Spanish. Thank you to the many contributors who make CircuitPython excellent!

Many new boards are now supported by CircuitPython 4.0.0. Check out the new circuitpython.org/downloads page for full list of all available versions.

It’s not too late to contribute to CircuitPython! Check out this guide for details. We’re always looking to improve and expect many stable releases in the 4.x line to happen through the summer. Subscribe to the Python for Microcontrollers newsletter on adafruitdaily.com for the latest news for all things Python.

CircuitPython on Python Podcast!

init

Podcast.init has stories of the people that make the Python community great, here’s one with CircuitPython and Scott! Hardware Hacking Made Easy With CircuitPython, Episode 212

“Learning to program can be a frustrating process, because even the simplest code relies on a complex stack of other moving pieces to function. When working with a microcontroller you are in full control of everything, so there are fewer concepts that need to be understood in order to build a functioning project. CircuitPython is a platform for beginner developers that provides easy to use abstractions for working with hardware devices. In this episode, Scott Shawcroft explains how the project got started, how it relates to MicroPython, some of the cool ways that it is being used, and how you can get started with it today. If you are interested in playing with low cost devices without having to learn and use C, then give this a listen and start tinkering!”

Python snakes its way to MakeCode

MakeCode Python

It turns out there is a Python mode in Microsoft MakeCode! Here’s how to find it: visit: https://maker.makecode.com/ and start a new Project. You’ll see the new option for Python at the top, that’s it! Here’s how to convert a MicroPython module(s) to PXT, pyconv.ts, and Static Python.

The History of CircuitPython

History of CircuitPython

A great summary of Scott’s talk, “The History of CircuitPython” at the 2019 PyCon Python Language Summit by A. Jesse Jiryu Davis –

To build a Python for Adafruit’s needs, Shawcroft forked MicroPython and created a new project, CircuitPython. In his Language Summit talk, he emphasized it is a “friendly fork”: both projects are MIT-licensed and share improvements in both directions. In contrast to MicroPython’s hardware APIs that vary by chip, CircuitPython has one hardware API, allowing Adafruit to write one set of libraries for them all.

Dr Sarah Wiseman, lecturer in computer science at Goldsmiths, University of London, said: “The Adafruit Circuit Playgrounds are a fantastic opportunity to do some rapid prototyping with participants. The inbuilt functionality on the boards means that you don’t need much experience with electronics to take a concept from idea to reality.” The research team, including Dr. Joanne Hinds, Research Associate at Bath, is inviting people to take part in a creative element of the study by drawing their cyber security concerns and solutions. The findings will help the team to develop more innovative, creative ways to tackle cyber security problems.

CircuitPython Hands-On Workshop

CircuitPython hands-on workshop recap from last week, Uri writes:

“Thanks Phillip! We had the workshop, and it went great! We had about 30 attendees (some of them worked together), and some of them came up with really creative stuff (such as using the accelerometer input to play different notes on the speaker). Most importantly, we got excellent feedback from the attendees and some attendees also shared their experience on Twitter. We’re now compiling a short summary video, and will publish it in a few days, already looking forward to the next workshop!”

Kickstarters

Some recent Kickstarters could run CircuitPython, so if ya back’em, post in the project’s comments and request it. Depending on the chip, it’s pretty easy to add. For the PocketScreen, we already support the ATSAMD21G18 so the creator would only need to make a new ‘board definition’ with the name, VID/PID and the pinouts available. This recent pull request has the basics of what is required. Want to try it out? Build the variant on your own here. You can test it on your board before submitting the PR.

Call for help – CircuitPython messaging to other languages!

Hello world

We posted on the Adafruit blog about bringing CircuitPython messaging to other languages, one of the exciting features of CircuitPython 4.x is translated control and error messages. Native language messages will help non-native English speakers understand what is happening in CircuitPython even though the Python keywords and APIs will still be in English. If you would like to help, please post to the main issue on GitHub and join us on Discord.

We made this graphic with translated text, we could use your help with that to make sure we got the text right, please check out the text in the image – if there is anything we did not get correct, please let us know. Dan sent me this handy site too.
