The need for speed, CircuitPython 4.1.0 Beta 0 Released!

CircuitPython 4.1.0 Beta 0

CircuitPython 4.1.0 Beta 0 Released! 4.1.0’s biggest feature is speed! General execution of Python should be 2-5x faster and display refreshing will be faster as well.

This is the first beta version for testing. It shouldn’t break any code compatible with previous 4.x releases. Please use the latest 4.x stable release (available from the new website!) when first starting with CircuitPython. It is stable.

Download it now from circuitpython.orgfull release notes.

Interested in Python or programming microcontrollers with Python?

If you can spare a few minutes, the interns at Microsoft Garage in Vancouver need your input for a user testing a new PythonHardware Visual Studio Code plugin – Microsoft Garage Survey.

Hello there, we’re a group of interns at Microsoft Vancouver, working in The Garage! We’re looking for insights into your experience around physical computing projects. As well as your interest in trying out a new method of development for your project – say goodbye to waiting for your code to build and compile inside Arduino IDE with C/C++, Python is here to help! This survey will only take 3 – 5 minutes and your insights are very valuable to us!

Thanks, Nina!

EuroPython 2019 attendees getting CircuitPython-powered PewPew Game Consoles!

PewPew

The device was created and designed by Radomir Dopieralski, a long time EuroPython regular and enthusiastic Python device and robotics builder.

PewPew

The PewPew is a simplified game console, programmable with CircuitPython, a variant of MicroPython. It comes with a 64 LED display and a set of small buttons to drive the console. EuroPython organizers are looking for attendees to help Radomir with workshops on the PewPew. See more on the blog post and on the PewPew workshop page.

EuroPython 2019 will be in Basel, Switzerland, July 8-14. More details.

Console-based serial terminal for Windows/Visual Studio Code

VS Terminal

From the CircuitPython forums, Fasteddy516 writes –

“I’ve written a simple serial terminal in C# that runs as a Windows Console application (i.e. in command prompt or Powershell). It should work with most devices that show up as “COMx” in Device Manager, but I wrote it specifically to work in a terminal window in Visual Studio Code with CircuitPython devices. It includes COM port auto detection, automatic re-connection (if you disconnect and reconnect your device), and uses USB VID and PID values to identify and give preference to CircuitPython-capable devices. The idea was to get a serial monitor in VSCode that was as simple and functional as the serial monitor in the Mu editor. (I like the Mu editor quite a bit, but I do a lot of other work in Visual Studio Code and found switching between the two frustrating – particularly since I use CTRL-H in VSCode all the time!) I’ve attached a screenshot to this message showing it in action in a Visual Studio Code terminal window. Everything is available on Github, so anyone who is interested is welcome to check it out. If you find it useful (or not), I’d love to hear from you!”

Python predicted to overtake C and Java in next 4 years.

Python’s ascent continues among software developers, bolstered by its usability compared with Java and C – ZDNet. Here’s the TIOBE Index for June 2019.

“This month Python has reached again an all time high in TIOBE index of 8.5%. If Python can keep this pace, it will probably replace C and Java in 3 to 4 years time, thus becoming the most popular programming language of the world. The main reason for this is that software engineering is booming. It attracts lots of newcomers to the field. Java’s way of programming is too verbose for beginners. In order to fully understand and run a simple program such as “hello world” in Java you need to have knowledge of classes, static methods and packages. In C this is a bit easier, but then you will be hit in the face with explicit memory management. In Python this is just a one-liner. Enough said.”

Grow with Python

4-H base kit

The Adafruit 4-H Circuit Playground Express Base Kit is now in stock. We are super pleased to enjoy a partnership with an engaging, empowering foundation like 4-H. Here at Adafruit we drive ourselves to “be excellent”, and 4-H’s motto is “to make the best better.” Though typically thought of as an agriculturally focused organization, 4-H today focuses on citizenship, healthy living, science, engineering, and technology programs. As far as inspiring the next generation of makers and leaders, we like to think we have a lot in common!

It’s the 4-H Circuit Playground Express Base Kit! It provides the few things you’ll need to get started with the new Circuit Playground Express – Adafruit.

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.

Codecademy “Learn Hardware Programming with CircuitPython”

Codecademy 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.
