What do you want from CircuitPython in 2020?

CircuitPython2020

As 2020 starts, let’s take some time to set goals for CircuitPython in 2020. Just like 2019 (full summary here), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post:

We want to hear from you. When you post, please add #CircuitPython2020 and email circuitpython2020@adafruit.com to let us know about your post so we can blog it up here. The post can cover any topic related to CircuitPython. Here are some specific topics you could address:

Here are a few from the community so far!

These, of course, are just ideas to start from. Please us know about all ideas you have for CircuitPython. We’ll read these over the first half of January. After the January 13th CircuitPython weekly, we’ll draft an overarching vision post for CircuitPython in 2020 and discuss it in the following meeting. Thanks to the Rust folks for the inspiration.

Initial CircuitPython MIMXRT10XX port implementation

NXP

NXP

It begins! The commit adds the NXP i.MX RT10XX series port, so far supporting the RT1011 and RT1062 chips, but the whole family is very similar so it’s easy to expand. CircuitPython snakes its way to the powerful NXP i.MX RT family of MCUs, 500+ MHz, up to 1 MB RAM. Arturo is working on 2 Feathers: RT1011 + ESP32, and RT1062 with more GPIOs broken out (including the LCD interface) and a SD card – GitHub.

The top product of the decade for Adafruit is CircuitPython powered

Top of the decade

Top of the decade

Out of all the products we’ve had in the last 10 years, Circuit Playground Express is the top selling, and it’s only been around for a few years. One of the biggest reasons is that so many people love writing code, and learning, using Python. CircuitPython runs great on this board and it’s been a joy to see so many people use this board to learn and share, thank you! – Adafruit.

“an Adafruit FT232H Breakout, $15, which Limor Fried, founder of Adafruit, called the “modern parallel port”. It’s a USB bridge that you can use to speak useful, well-known protocols like SPI and I2C, or — in our case — less-useful, dance protocols via general purpose input/output (GPIO) pins. This thing is super cool: extremely approachable, easy to use, no IDE. It’s a great starting point for anyone who wants to write software that can control simple electronics.”

Feather Bluefruit Sense

Since we’ve experimented with adding all sorts of sensors to our new CLUE board (see previous newsletters for more info about CLUE) – we thought we’d try adding the same bevy of sensor goodness to a Feather nRF52840. We removed the SWD connector and also the optional 32 Khz crystal. In their place we added a PDM mic, LSM6DS33 accel/gyro + LIS3MDL magnetometer, SHT3x humidity sensor, BMP280 or DPS310 barometric pressure sensor, and APDS-9960 color/light/proximity/gesture sensor. It should be a fun little Feather board, and it will pair very nicely with an ADALOGGER FeatherWing for RTC+SD card datalogging – YouTube.

This week I did a bunch of PR reviews and debugging to continue the CircuitPython libraries’ migration to GitHub Actions. The end is in sight! I’ve also started working on migrating the Arduino libraries that I’ve worked on to Actions as well. I also did some editing to the MCP4728 guide to clarify some sections and add additional examples to my explanation of how Vref works.

I had a lovely holiday and I hope everyone else did as well. I’m picking up this week where I left off, updating the CircuitPython Made Easy on Circuit Playground Express and Bluefruit guide to support both Express and Bluefruit using the latest updates to the Circuit Playground library. The guide update is still in progress as of Friday, but is nearly complete. The final thing to add is a page for the new sound features available for Circuit Playground Bluefruit. It should be ready to go very soon. The guide is already live, so you can check it out now. After that, I’ll be starting a new project involving motors and CircuitPython. We have a lot of motor support, but not nearly enough examples, so we’re going to take care of that with an upcoming motor party. Keep an eye out for that!

…back to work polishing some pull requests related to JEplayer and getting back to feature work there if nothing else grabs my attention. In the realm of personal projects, I’m creating a hand-wired keyboard with a 3D printed enclosure. So I am excited to learn about KMK: Clackety Keyboards Powered by Python and plan to put it to use soon.

This past week I caught up with all of my messages and since I didn’t have my hardware with me on Monday, I focused on updating the circuitpython.org website and added a counter to display the number of boards that support CircuitPython as well as the Blinka boards. I finished up working on the Animated Gif Player and refactored it into a class. I am currently working on writing up a guide for this. There is still lots of room for improvement and I plan on improving it over time, but feel it’s in a great place to be able to implement any improvements.

I started working on HT16K33 updates and implemented a function from a previous library called set_digit_raw() and have added that to the library. I also spent some time working on getting the Onion Omega2 up and running to test a Pull Request and I am in a good position to help with any remaining Blinka development.

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.
