CircuitPython 8.2.2 Launched! @circuitpython « Adafruit Industries – Makers, hackers, artists, designers and engineers!


From the GitHub launch web page:

That is CircuitPython 8.2.2, the most recent bugfix revision of CircuitPython, and is a brand new secure launch.

WARNING for nRF52 boards solely: In case your board has an nRF52 UF2 bootloader whose model is earlier than 0.6.1, you won’t be able to load CircuitPython 8.2.0 and later. The 8.2.0 firmware is bigger than what the bootloader can deal with. See these directions for updating your bootloader.

Notable modifications to eight.2.2 since 8.2.1

  • Exchange expired Adafruit IO SSL certificates.

Notable modifications to eight.2.2 since 8.1.0

  • Continued enhancement of synthio.
  • RP2040 alarm.sleep_memory.

Obtain from circuitpython.org

Firmware downloads can be found from the downloads web page on circuitpython.org. The positioning makes it straightforward to pick the right file and language on your board.

Set up

To put in comply with the directions within the Welcome to CircuitPython! information. To put in the most recent libraries, see this web page in that information.

Attempt the most recent model of the Mu editor for creating and enhancing your CircuitPython packages and for simple entry to the CircuitPython serial connection (the REPL).


Documentation is accessible in readthedocs.io.

Port standing

CircuitPython has a lot of “ports” which can be the core implementations for various microcontroller households. Stability varies on a per-port foundation. As of this launch, these ports are contemplate secure (however see Recognized Points under):

  • atmel-samd: Microchip SAMD21, SAMx5x
  • cxd56: Sony Spresense
  • espressif: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C3
  • nrf: Nordic nRF52840, nRF52833
  • raspberrypi: Raspberry Pi RP2040
  • stm: ST STM32F4 chip household

These ports are thought-about alpha and can have bugs and lacking performance:

  • broadcom: Raspberry Pi boards reminiscent of RPi 4, RPi Zero 2W
  • litex: fomu
  • mimxrt10xx: NXP i.MX RT10xxx
  • silabs: Silicon Labs MG24 household
  • stm: ST non-STM32F4 chip households

Adjustments since 8.2.1

Fixes and enhancements

  • Exchange expired Adafruit IO SSL certificates. #8227. Thanks @jepler for PR and @brentru for certificates replace.

Port and board-specific modifications










Particular person boards

Documentation modifications

Construct and infrastructure modifications

Translation additions and enhancements

New boards since 8.2.1

Recognized points

  • ESP32-S3 has important points with I2C units that sleep or use clock stretching. Retry operations on these units as obligatory, or use ESP32-S2 boards.
  • Espressif boards have ESP-IDF storage leaks and sometimes crash after prolonged WiFi use.
  • See https://github.com/adafruit/circuitpython/points for different points, together with points nonetheless to be addressed for:
