Test & Code – Python Testing & Development 84: CircuitPython – Scott Shawcroft


Test & Code – Python Testing & Development 84: CircuitPython with Scott Shawcroft

“Adafruit enables beginners to make amazing hardware/software projects. With CircuitPython, these projects can now use Python. The combination of Python’s ease of use and Adafruit’s super cool hardware and a focus on a successful beginner experience makes learning to write code that controls hardware super fun. In this episode, Scott Shawcroft, the project lead, talks about the past, present, and future of CircuitPython, and discusses the focus on the beginner. We also discuss contributing to the project, testing CircuitPython, and many of the cool projects and hardware boards that can use CircuitPython, and Blinka, a library to allow you to use “CircuitPython APIs for non-CircuitPython versions of Python such as CPython on Linux and MicroPython,” including Raspberry Pi.”

Happy 28th Birthday Linux!

Linux turns 28

Linux turns 28August 25, 1991 comp.os.minix newsgroup:

“Hello everybody out there using minix – I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I’d like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things). I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work. This implies that I’ll get something practical within a few months, and I’d like to know what features most people would want. Any suggestions are welcome, but I won’t promise I’ll implement them ?? Linus PS. Yes – it’s free of any minix code, and it has a multi-threaded fs. It is NOT portable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that’s all I have :-(.”

First kernel release was September 17, 1991, and October 5th 1991 was 0.02, the first public release. The video above is from the 20 year anniversary.

TI-83 Premium CE 5.3.6+ blocks third party firmware TI-Python


Looks like the formerly CircuitPython-powered TI calculator is blocking 3rd party firmware now. It was first a fork of CircuitPython, then the name was changed, now we’re not sure exactly what is going on with using 3rd party firmware, more details on TI-Planet. Previous coverage and more here – Adafruit.

What are Bryan, Dan, and Melissa up to?


“Bryan wrote the CircuitPython driver for the MSA301 low cost 3-axis accelerometer, and wrote the guide to go along with it. Afterwards, he assembled and started the process of testing prototypes of the TLV493 board designed by Kattni.”


“Dan debugged BLE on the new Circuit Playground Bluefruit, and it’s now working fine. He’s gotten BLE HID (Keyboard) working from CircuitPython, sending keystrokes over BLE to Linux, Windows, MacOS, and Android, and is still debugging iOS support.”


“Melissa finished up adding a CircuitPython Display Quickstart section to the last three display guides. After that Melissa wrote a guide for controlling an RGB Message Panel from a Stream Deck. This guide includes the first design done in Fusion 360.”

MAKE is back, and posting on the MAKE blog again, here is MAKE’s post about the latest CircuitPython (and more) device, Monster M4sk – MAKE. This quote is the best ??

“It is important to reiterate, in case you missed it in the list above… the nose is capacitive touch so you can boop it. There’s also another cool feature of this board. You can snap it in the middle and connect both sides via a cable so that you can place the eyes further apart if they are part of your costume or suit.”

Call for help – CircuitPython messaging to other languages!

Hello world

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.
