CircuitPython 7.0.0 Released! @circuitpython

This is CircuitPython 7.0.0, the latest major revision of CircuitPython, and is a new stable release.

Notable additions to 7.0.0 since 6.3.0

  • Support for the CircuitPython development workflow over BLE.
  • Camera support on ESP32S2.
  • qrio: QR code decoding.
  • The keypad key-scanning module.
  • Run-time customization of USB devices.
  • Merging in of MicroPython fixes and enhancements as of MicroPython 1.16.
  • _pixelbuf is now adafruit_pixelbuf.
  • colorwheel() routine moved to rainbowio.
  • supervisor.ticks_ms() to allow easier time-keeping.
  • Simplifications to the RGB status LED codes.
  • A clocking fix for a few samples of RP2040 boards.
  • Rework of vectorio and some of its API. VectorShape is no longer needed for user code.
  • atexit module.
  • getpass module.
  • traceback module.
  • supervisor.get_previous_traceback().
  • board.LED now consistently present on all boards that have such an LED.
  • PulseOut no longer needs a PWMOut.
  • Unicode filename support.
  • Board ID is now in boot_out.txt and available as board.board_id.
  • aesio on for full builds by default.

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).

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, atmel-samd, cxd56 (Spresense), esp32s2, nrf,raspberrypi, stm for the F4 family are stable. stm for other STM chip families is 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 7.0.0-rc.3

This release is a relabeling of 7.0.0-rc.3 and is otherwise the same as that release.

Breaking changes and deprecations since 6.x

  • The RGB status LED codes have changed for clarity and to save power.
  • PWMOut is now only in pwmio, and is no longer in both pulseio and pwomio.
  • colorwheel() has been moved from _pixelbuf to rainbowio.
  • displayio.Group no longer has a max_size parameter.
  • vectorio: Rectangle, Circle, and Polygon are added directly to a Group; VectorShape is not needed.
  • Using a PWMOut for PulseOut is deprecated and will be removed in 8.0.0.
  • gamepad is removed: use keypad. gamepadshift is still present but will be removed in 8.0.0.
  • settings.py and settings.txt are no longer alternative names for boot.py.
  • The default for displayio.Display.refresh(..., minimimum_frames_per_second, ...) is now 0.
  • displayio.Display() argument set_vertical_scroll argument is deprecated and will be removed in 8.0.0.
  • displayio.ParallelBus is now available as parallelbus.ParallelBus and will be removed from displayio in 8.0.0.
  • busio.OneWire/bitbangio.OneWire is now available as onewireio.OneWire and will be removed from busio and bitbangio in 8.0.0.
