CircuitPython 9.1.3 Launched! « Adafruit Industries – Makers, hackers, artists, designers and engineers!

From the GitHub launch web page:

That is CircuitPython 9.1.3, the newest bugfix launch of CircuitPython, and is a brand new steady launch.

WARNING for nRF52 boards solely: In case your board has an nRF52 UF2 bootloader whose model is earlier than 0.6.1, you will be unable to load CircuitPython 8.2.0 and later, attributable to elevated dimension of the firmware. See these directions for updating your bootloader.

Highlights of this launch

• Repair Espressif ESP32-C6 UART creation.
• Adafruit Qualia ESP32-S3 RGB666: repair show tearing.
• Pull request merge builds for steady branches, not simply the fundamental department, are actually uploaded to AWS S3.
• Repair Espressif board-specific pin initialization. This fixes board.NEOPIXEL_I2C_POWER initialization on the Adafruit Feather C6.

Obtain from circuitpython.org

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

Set up

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

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

Documentation

Documentation is out there in readthedocs.io.

Port standing

CircuitPython has plenty 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 think about steady (however see Recognized Points beneath):

• atmel-samd: Microchip SAMD21, SAMx5x
• cxd56: Sony Spresense
• espressif: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C2, ESP32-C3, ESP32-C6
• nordic: Nordic nRF52840, nRF52833
• raspberrypi: Raspberry Pi RP2040
• stm: ST STM32F4 chip household

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

• broadcom: Raspberry Pi boards similar to RPi 4, RPi Zero 2W
• litex: fomu
• mimxrt10xx: NXP i.MX RT10xxx
• renode: {hardware} simulator
• silabs: Silicon Labs MG24 household
• stm: ST non-STM32F4 chip households
