This is CircuitPython 10.0.0-alpha.7, an alpha release for 10.0.0. Further features, changes, and bug fixes will be added before the final release of 10.0.0.

Highlights of this release

  • Update frozen modules.
  • Merge updates from MicroPython v1.24.1.
  • Espressif:
    • Expand the CircuitPython firmware partition on non-USB boards, allowing more space for features in the future.
    • Fix pulseio.PulseIn length limitation.
    • Initial implementation of MicroROS.
  • Nordic: reinitialize BLE properly after deep sleep.
  • Incorporate fixes from CircuitPython 9.2.8 and later:
    • Fix deque bug.
    • Fix I2S audio file read causing memory corruption.
    • Support "Spectra6" six-color e-ink displays.
    • Fix audiodelays.Delay when freq_shift=True.
    • Board fixes.

Incompatibility warnings

  • Starting with 10.0.0-alpha.5, the Adafruit Feather S3 4MB Flash 2MB PSRAM board requires TinyUF2 bootloader 0.31.0 or later (update instructions). This version of the bootloader removes the OTA update partition (not used) and doubles the size of the firmware code partition. This change for this particular board is a trial. If all goes well, all 4MB Flash ESP32-S2 and ESP-S3 boards will have this change applied in a later 10.0.0 alpha or beta release.
  • synthio.BlockBiquad has been renamed to synthio.Biquad. The old deprecatedsynthio.Biquad has been removed, as well as synthio.Synthesizer.low_pass_filter, synthio.Synthesizer.high_pass_filter, and synthio.Synthesizer.band_pass_filter. Coefficients from biquad_filter_state have been moved into synthio_biquad (biquad_filter_state is still used for input and output state).
  • The displayio bindings deprecated in 9.x.x have been removed:
    • busdisplay.BusDisplay replaces displayio.Display.
    • fourwire.FourWire replaces displayio.Fourwire.
    • epaperdisplay.EPaperDisplay replaces displayio.EPaperDisplay.
    • i2cdisplaybus.I2CDisplayBus replaces displayio.I2CDisplay.
  • os.uname().sysname and os.uname().nodename now are set to MICROPY_HW_MCU_NAME uniformly across all ports.
  • watchdog.WatchDogTimer.deinit() is removed.
  • _asyncio removed push_head, push_sorted, pop_head. Ensure you are using the latest version of the asyncio CircuitPython library.
  • sys.print_exception() is removed. Use traceback.print_exception() instead. The exception object returned by sys.exc_info() is now a traceback module compatible object.

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 the Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.

Try code.circuitpython.org or 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).

Documentation

Documentation is available in readthedocs.io.

Port status

CircuitPython has a number of "ports" that are the core implementations for different microcontroller families. Stability varies on a per-port basis. As of this release, these ports are consider stable (but see Known Issues below):

  • 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, RP2350
  • stm: ST STM32F4 chip family

These ports are considered alpha and will have bugs and missing functionality:

  • analog: Analog Devices MAX32690
  • broadcom: Raspberry Pi boards such as RPi 4, RPi Zero 2W
  • espressif: ESP32-P4, ESP32-H2
  • litex: fomu
  • mimxrt10xx: NXP i.MX RT10xxx
  • renode: hardware simulator
  • silabs: Silicon Labs MG24 family
  • stm: ST non-STM32F4 chip families
  • zephyr: multiplatform RTOS: testing with Nordic nRF5340 and nRF54L15, Renesas RA6M5, ST STM32H7
