CircuitPython libraries on the Raspberry Pi!

CircuitPython's Blinka loves Raspberry Pi

Kattni, Brennen and Ladyada have been hard at work over the last few weeks to bring our 90 or so CircuitPython libraries to the Raspberry Pi and “normal” Python (usually referred to as CPython or just Python). Many guides are now updated with CircuitPython instructions that work both on CircuitPython and CPython. Libraries are available through the standard Python pip install process.

This has been a great way to verify that CircuitPython is indeed a subset of CPython. It unifies our library style across CircuitPython and CPython to make it easier to grow from a simple microcontroller CircuitPython to the more advanced CPython on Linux.

The work isn’t finished quite yet. In the coming weeks more guides will be updated with CircuitPython library support. Check out the Updated Guides section below to see all of the week’s updates. Follow the CircuitPython on Linux and Raspberry Pi guide to get started. The legacy Python libraries will also be archived on GitHub in favor of the CircuitPython versions.

Adafruit CircuitPython Weekly for August 20th, 2018

Hallowing – A new member of the family

this is hallowing

Are you the kind of person who doesn’t like taking down the skeletons and spiders until after January? This is electronics at its most spooky! The Adafruit HalloWing is a skull-shaped ATSAMD21 board with a ton of extras built in to make for an adorable wearable, badge, development kit, or the engine for your next cosplay or prop.

On the front is a cute 1.44” sized 128×128 full color TFT. Our default example code has our spooky eye demo running but you can use it for anything you like to display in glorious color.

There’s also 4 fang-teeth below the display, these are analog/capacitive touch inputs with big alligator-clip holes.

It has CircuitPython build support so you can pick your favorite development language! The extra 8 MB of SPI Flash is great for sound effects projects where you want to play up to 3 minutes of WAV files – Adafruit HalloWing M0 Express & learn guide.

It’s not out yet 🙂

Updated Guides – Now With More Python!

You can use CircuitPython on Raspberry Pi! We’re updating all of our CircuitPython guides to show how to wire up sensors to your Raspberry Pi, and load the necessary CircuitPython libraries to get going using them with Python. We’ll be including the udpates here so you can easily keep track of which sensors are ready to go. Check it out!

Help bring CircuitPython 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. We were inspired by the awesome translation work done in mu 1.0.0. (They even discussed the benefit translating error messages.) We saw this and loved the idea of both mu and CircuitPython being in one’s native language.

So, we’ve added the mechanics to CircuitPython that allow us to translate strings at build time. However, that’s not enough! We need folks to translate the strings themselves.

If you want to help, then please post to the main issue on GitHub and join us on Discord. Thanks!
