ICYMI: The most wonderful time of the year … for Python! Happy Holidays! #Python #Adafruit #CircuitPython #ICYMI @circuitpython @micropython @ThePSF @Adafruit

ICYMI (In case you missed it) – Tuesday’s Python for Microcontrollers Newsletter from AdafruitDaily.com went out – if you missed it, subscribe now!

Next one goes out in a week and it’s the best way to keep up with all things Python for hardware, it’s the fastest growing newsletter out of ALL the Adafruit newsletters!


Happy Holidays – Thank you from the Python on microcontroller authors, and all of Adafruit!

Thank you to all the readers who subscribe and read this newsletter every week. Today happens to be Christmas Day and we set the newsletter to be sent out as usual to keep up with all the things happening in the world of Python on hardware. We’ll have one next week as well, which just happens to be New Years Day!

It’s been a fantastic year for Python on hardware and we appreciate all the support to keep doing this. We’re up to 2 years of publishing and over 4,000+ subscribers already, the entire Adafruit team and community thanks you! – Video.

CircuitPython in 2019

As 2018 comes to a close we like to reflect on how the year went and set goals for 2019. In the last two years (2017, 2018) this has been a blog post by Scott (aka tannewt). For 2019, we’d like to do it a bit differently. This time we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet.

We’ll read these over the holidays and into the first half of January. After the January 14th CircuitPython weekly we’ll draft an overarching vision post for CircuitPython in 2019 and discuss it in the following meeting.

See the blog post for more details.

Video of a test of the NeoTrellis M4’s STEMMA interface connected to multiple devices: dual 12-bit DAC for CV/Gate, a ToF sensor for gesture control, and an alphanumeric LED display to indicate distance from the ToF sensor. The DAC CV/Gate signals were sent to an off-camera Eurorack quantizing synth. All code written in CircuitPython by Cedar GroveYouTube.

Made with Mu, not that Mu, the other one

To clear up any confusion before it starts, Project Mu is a new project from Microsoft for devices to support Firmware-as-a-Service to Open Source (FaaS) – Microsoft. It looks cool, however – it has nothing to do with the Mu we usually cover here 🙂

One thing we did not know is that Mu, the Python one, has turtle built in, this means you can use it to make excellent art and more. Here’s a “tree blossom” – Twitter.

Coming soon

Updated Guides – Now With More Python!

You can use CircuitPython libraries on Raspberry Pi! We’re updating all of our CircuitPython guides to show how to wire up sensors to your Raspberry Pi, and load the necessary CircuitPython libraries to get going using them with Python. We’ll be including the updates here so you can easily keep track of which sensors are ready to go. Check it out!

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 drivers, download the Adafruit CircuitPython Library 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! Interested in helping with current libraries? Check out this GitHub issue on CircuitPython for an overview of the State of the CircuitPython Libraries, updated each week. We’ve included open issues from the library issue lists, 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 channel on the Adafruit Discord. Feel free to contact Kattni (@kattni) with any questions.

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

The current number of CircuitPython libraries is 119!

New Libraries!

Call for help – CircuitPython messaging to other languages!

We recently 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.
