CircuitPython 6.2.0 Released!

by danhalbert on Mon Apr 05, 2021 5:41 pm

This is CircuitPython 6.2.0, the latest minor revision of CircuitPython, and is a new stable release. See Port status below for details on port stability, and Known Issues for known problems. If you find any issues with this release, please file an issue.

Download from circuitpython.org
Firmware downloads are available from the downloads page on circuitpython.org. The site makes it easy to select the correct file and language for your board.

Installation
To install follow the instructions in our new Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.

Try the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).

Port status
CircuitPython has a number of "ports" that are the core implementation for a variety of microcontroller families. Stability varies on a per-port basis. As of this release, atmel-samd, cxd56 (Spresense), nrf, and stm for the F4 family are stable. esp32s2, raspberrypi, and stm for other STM chip families are being actively improved but may be missing functionality and have bugs. litex and mimxrt10xx are in an alpha state and will have bugs and missing functionality.

Changes since 6.2.-rc.0
  • Fix regression of HID Mouse support on MacOS. #4558. Thanks @dhalbert.
Change since 6.1.0
The changes are too extensive to list here. Please see these releases for details:

Breaking changes since 5.x
  • i2cslave is now i2cperipheral and the class in it is changed as well.
  • The stop kwarg has been removed from I2C.writeto(). If no stop is desired, then use writeto_then_readfrom.
  • The default speed of busio.I2C and board.I2C is now 100khz, not 400khz as before. Use busio.I2C to set the speed explicitly. #3471 Thanks @caternuson, @ladyada, @hierophect and @tannewt
  • _bleio.ConnectionError has be removed. Code will now raise the native ConnectionError instead.
Known issues
Thanks
Thank you to all who used, tested, and contributed since 6.1.0. Join us on the Discord chat to collaborate.

Documentation
Documentation is available in readthedocs.io.

This release is based on MicroPython 1.9.4 @25ae98f. Support upstream MicroPython by purchasing a PyBoard (from Adafruit here) or sponsoring MicroPython on GitHub.

Translations
One important feature of CircuitPython is translated control and error messages. With the help of fellow open source project Weblate, we're making it even easier to add or improve translations. Sign in with an existing account such as Github, Google or Facebook and start contributing through a simple web interface. No forks or pull requests needed!

Troubleshooting
Check out this guide for info on common problems with CircuitPython. If you are still having issues, then post to the Adafruit Support Forums and join Discord.

I can't find where to download Circuit Python. The Adafruit download page takes me to the Microsoft Store and it is not shown there. I am current using Arduino on my Playground Circuit Express but want to try Circuit Python.
