CircuitPython 7.1.0 Release Candidate 0 Released! @circuitpython

From the GitHub release page:

This is CircuitPython 7.1.0-rc.0, the initial release candidate for CircuitPython 7.1.0. We believe it is stable, but want to give time for further testing.

Notable additions to 7.1.0 since 7.0.0

  • Initial port for Raspberry Pi Broadcom-based boards.
  • Preliminary support for asyncio cooperative multitasking.
  • bitmaptools: dithering and alphablend are new.
  • keypad.Events now include timestamps.
  • framebufferio: support for IS31FL3741.
  • Espressif now provides I2CPeripheral, WiFi monitor mode, setting MAC address, ESP32-C3 support, ParallelImageCapture.
  • gifio.GifWriter is new.
  • HID now provides boot device and feature report support.
  • rotaryio now allows setting the divisor of counts per transition.
  • SAMD now provides watchdog, and alarm with sleep.
  • SAMx5 boards now all have sleep support.
  • The STM port now provides STM32L4R5 support.
  • MicroPython 1.17 has been merged in.
  • Russian translation.

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 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. broadcom (Raspberry Pi), litex and mimxrt10xx are in an alpha state and will have bugs and missing functionality.
