PyOhio – Kattni’s Keynote!

PyOhio was July 27-28, 2019 in Columbus, Ohio, USA! Kattni Rembor was the opening keynote speaker!

“In trying to learn Python, I stumbled into a passion I had never considered. My path began with learning Python on hardware. Through mentorship and the help of friends, I began to flourish. Since then, I have continued to contribute in ways I never thought possible, between code, community, and becoming a mentor myself. This is the story of my journey and how mentorship can change lives.”

PyOhio is a non-profit annual Python community conference held in Columbus, OH. It was free to attend and welcomes anyone with an interest in Python. Content ranged from beginner to advanced and was intended to be relevant to all types of Python users: students, software professionals, scientists, hobbyists, and anyone looking to learn more. There were keynotes, tutorials, talks, sprints, open spaces, lightning talks and more – PyOhio.

STM32 support snakes its way to CircuitPython!

This is a bit of a coming soon but deserves its own news item! Adding STM32 Discovery F412G and F411E support to CircuitPython by @hierophect – GitHub:

“This PR adds rudimentary support for the STM32F4 series. Supported features are REPL access over UART, and Microcontroller, Board and DigitalIO object support. Specify USB=FALSE when building. Also includes minor additions to Main.c and supervisor files to add preprocessor exclusion of optional modules for early stage ports, and fixes a potential bug in the nRF port.”

Issue 84 – The MagPi Magazine: Control servos with CircuitPython & Raspberry Pi

Issue 84 – The MagPi Magazine:

“Get your Raspberry Pi 4 Starter Guide in The MagPi magazine issue #84. Get to know your Raspberry Pi 4 with our in-depth starter guide. We’ll help you take the first steps with your new computer: discover the best way to set up and use a Raspberry Pi 4. Raspberry Pi 4 comes with a whole new operating system, called Raspbian ‘Buster’. Our starter guide has advice on the new features, and how to get the most from Buster. Coding and making with Raspberry Pi is the most fun you can have with a computer. And our starter guide will get you on your way.”

Issue 21 – HackSpace Magazine: CircuitPython Storage

CircuitPython storage: Save data to the flash drive for later retrieval, by Ben Everard:

“While investigating the performance of the latest CircuitPython release, we wrote a program to perform some benchmarks and then save the results to the storage so that it can be read by the computer the next time that the device is plugged in. Flash different versions of CircuitPython to the board and, voila’, we had all our benchmarks in one handy place.”

The Gizmo for Circuit Playground!

Extend and expand CircuitPython-powered Circuit Playground Express projects with a bolt on Perma-Proto that lets you connect solderable circuits in a sturdy and reliable fashion. This PCB looks just like a solderless breadboard, but has permanently affixed M3 standoffs that act as mechanical and electrical connections. Solder to the gold-plated traces to create your custom invention – Adafruit.

STEMMA and STEMMA QT – easy connections!

Here is our latest STEMMA Sunday video! – YouTube. STEMMA is not an original idea, we’re working within an ecosystem of many other plug and play systems. We started STEMMA in 2014, and intended it to be compatible with Grove only (’cause that’s all that existed at the time) but then when Qwiic came around in 2017, we added a smaller connector so we could work with those parts too! STEMMA attempts to be as cross-compatible as possible with both Grove and Gravity (compatible connectors & 3-5V power/logic). STEMMA QT is cross-compatible with Qwiic – STEMMA QT connector/cable is same as Qwiic. You can use STEMMA QT devices with Qwiic devices/controllers. A complete guide, with cross-compatibility tables, is available now on learn.adafruit.com

Snekboard v0.2 Update: Snek sneks its way to CircuitPython

Snek sneks its way to CircuitPython, Keith writes –

“I included a W25Q16 2MB NOR flash chip on the board so that it could also run CircuitPython. Before finalizing the design, I thought it might be a good idea to actually get that running. I’ve submitted a pull request with the necessary changes. I hope to see that merged at some point, which will allow users to select between CircuitPython and snek.”

Made with Mu – A HyperCard inspired GUI framework for beginner developers in Python

A HyperCard inspired GUI framework for beginning developers in Python – GitHub.

Nicholas Tollervey is looking for feedback and more on PyperCard! – Twitter.

“A re-implementation of Adafruit’s CircuitPython PYOA module for non-CircuitPython computing environments. This module re-uses the JSON specification used to create HyperCard like “stacks” of states between which users transition in a Python-your-own-adventure style.”

Why Mu? Mu tries to make it as easy as possible to get started with programming but aims to help you graduate to “real” development tools soon after. Everything in Mu is the “real thing” but presented in as simple and obvious way possible. It’s like the toddling stage in learning to walk: you’re finding your feet and once you’re confident, you should move on and explore! Put simply, Mu aims to foster autonomy. Try out Mu today! – codewith.mu

Call for help – CircuitPython messaging to other languages!

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.

Codecademy “Learn Hardware Programming with CircuitPython”

Codecademy, an online interactive learning platform used by more than 45 million people, has teamed up with the leading manufacturer in STEAM electronics, Adafruit Industries, to create a coding course, “Learn Hardware Programming with CircuitPython”. The course is now available in the Codecademy catalog.

Python is a highly versatile, easy to learn programming language that a wide range of people, from visual effects artists in Hollywood to mission control at NASA, use to quickly solve problems. But you don’t need to be a rocket scientist to accomplish amazing things with it. This new course introduces programmers to Python by way of a microcontroller — CircuitPython — which is a Python-based programming language optimized for use on hardware.

CircuitPython’s hardware-ready design makes it easier than ever to program a variety of single-board computers, and this course gets you from no experience to working prototype faster than ever before. Codecademy’s interactive learning environment, combined with Adafruit’s highly rated Circuit Playground Express, present aspiring hardware hackers with a never-before-seen opportunity to learn hardware programming seamlessly online.

Whether for those who are new to programming, or for those who want to expand their skill set to include physical computing, this course will have students getting familiar with Python and creating incredible projects along the way. By the end, students will have built their own bike lights, drum machine, and even a moisture detector that can tell when it’s time to water a plant.

Visit Codecademy to access the Learn Hardware Programming with CircuitPython course and Adafruit to purchase a Circuit Playground Express.

Codecademy has helped more than 45 million people around the world upgrade their careers with technology skills. The company’s online interactive learning platform is widely recognized for providing an accessible, flexible, and engaging experience for beginners and experienced programmers alike. Codecademy has raised a total of $43 million from investors including Union Square Ventures, Kleiner Perkins, Index Ventures, Thrive Capital, Naspers, Yuri Milner and Richard Branson, most recently raising its $30 million Series C in July 2016.
