CircuitPython Project Bundle

BundleFly

When you get to the CircuitPython code section of an Adafruit Learn Guide, sometimes things can get a bit complicated. You not only have the code you need to upload to your device, but you likely also need to add some libraries that the code requires to run. This involved downloading all the libraries, digging through to find the ones you need, and copying them to your device. That was only the beginning on some projects, as those that include images and/or sound files required further downloading and copying of files. But, not anymore!

Now, with Project Bundles, you can download all the necessary code, libraries and, if needed, asset files with one click! We automatically check which libraries are required for the project and bundle them up for you. No more digging through a huge list of libraries to find the ones you need, or fiddling with looking for other files or dependencies. Download the Project Bundle, copy the contents to your device, and your code will simply work. We wanted to make this the easiest way to get a project working, regardless of whether you’re a beginner or an expert. We’ll also be adding this feature to popular IDEs as an add-on. Try it out with any Circuit Python guide on the Adafruit Learning System. Just look for the ‘Download Project Bundle’ button on the code page.

To download and use a Project Bundle:

In the Learning System – above any embedded code in a guide in the Adafruit Learn System, you’ll find a Download Project Bundle button.

Project Bundle download button

Click the button to download the Project Bundle zip.

Project Bundle zip downloaded

Open the Project Bundle zip to find the example code, all necessary libraries, and, if available, any images, sounds, etc.

Project Bundle unzipped

Simply copy all the files over to your CIRCUITPY drive, and you’re ready to go!

If you run into any problems or bugs, or would like to submit feedback, please file an issue on the Adafruit Learning System Guides GitHub repo.

CircuitPython Libraries!

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 libraries, download the Adafruit CircuitPython Library Bundle. For the latest community contributed libraries, download the CircuitPython Community 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! Have you written a library you’d like to make available? Submit it to the CircuitPython Community Bundle. Interested in helping with current libraries? Check out the CircuitPython.org Contributing page. We’ve included open pull requests and issues from the libraries, 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.

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

The current number of CircuitPython libraries is 340!

Updated Libraries!

Here’s this week’s updated CircuitPython libraries:

What’s the team up to this week?

What is the team up to this week? Let’s check in!

Dan

Experimental asyncio support will be in the next CircuitPython beta. I tweaked the MicroPython version of asyncio to work with CircuitPython, and it’s now a library. Along with this the latest builds of CircuitPython have also been adjusted to work with that library. Next, I’ll be working on a Learn Guide with a number of examples.

Jeff

It was an exciting week for me, as a number of half-finished projects were merged into the CircuitPython core. The most recent additions are dither and alphablend in the bitmaptools library. You can check out a short video about the functionality on YouTube.

Kattni

This past week, I finished up the overhaul of the Welcome to CircuitPython guide. Please check it out! It’s updated and better designed to provide a smooth experience for newcomers, while still offering up advanced knowledge to those who are looking for it. There are a couple of new pages as well, so take a look at those whether you’re new to the guide or quite familiar with it.

I merged a number of PRs to get many more libraries in line with the latest Pylint, and helped out by submitting a few myself. As of this writing there are still ~40 to go, but based on the speed with which that’s being addressed, I imagine everything will be done by the time this newsletter is published!

Next up is starting the guide for the Adafruit Monochrome 1.12” 128×128 OLED Graphic Display, a new OLED in the shop. Once complete, it’ll have everything you need to get started with your new display. Keep an eye out for it.

This past week, I was out sick for a few days, but I did manage to get the new Raspberry Pi OS working with the PiTFT in desktop mode. It ended up being one of those problems that could have had many possible causes, but the final solution was pretty simple.

Scott

This week I’ve been doing two things in parallel. First, I’ve gotten CircuitPython running on the Pi Zero 2W. Second, I’ve been working hard to add SD card support to CircuitPython on the Raspberry Pi. Adding SD card support will allow the CIRCUITPY drive to appear as it does when running on microcontrollers. Once SD card support is going (it’s very close) then I’ll polish things up and get them merged into main CircuitPython and released.

Upcoming events!

RISC-V Summit

RISC-V Summit brings the community together to show the power open collaboration can have on the processor industry. The audience spans across industries, organizations, workloads, and geographies to learn about the technology advancements in the RISC-V ecosystem and visibility of RISC-V successes. The event is December 6 – 8, in-person in San Francisco or virtually from anywhere in the world – Linux Foundation via Twitter.

PyCon US 2022

PyCon US 2022 planning is underway. The team is planning to host the event in person with an online component. April 27, 2022 – May 5, 2022. Head over to the PyCon US 2022 website for details about the conference and more information about the sponsorship program – PyCon Blog.

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.
