CircuitPython 8.0.0 Beta 4 Released! circuitpython « Adafruit Industries – Makers, Hackers, Artists, Designers, Engineers!

From Github version page:

This is it CircuitPython 8.0.0-beta.4, beta version for 8.0.0. It is relatively stable, but there will be more additions and fixes before the final release.

warning: The flash partition for the 2MB ESP32 and ESP32-C3 boards and the 4MB for ESP32-C3 boards has changed since version 8.0.0-beta.2. When loading 8.0.0-beta.3 or later via beta 2 (or vice versa), on these boards, CIRCUITPY will be erased and reformatted.

warning: The flash partition for Raspberry Pi Pico W has changed since version 8.0.0-beta.1. When downloading 8.0.0-beta.2 or later via beta.1 (or vice versa), on Pico W, CIRCUITPY will be erased and reformatted.

Notable changes to 8.0.0 since 7.3.0

Function Additions

    • Added WiFi workflow with browser-based device discovery, file system browsing, uploading, downloading, editing files, and serial/REPL connection (only available on Espressif at the moment).
    • Added a one-line status bar, which displays connection status, last exception, and version on the terminal window title or on the top line of the attached screen. Support for displaying a status bar is also being added to the Mu and Thonny editors.
    • .env or not Circle Specifies WiFI connection parameters, BLE name, and other startup values.
    • dotenv the support: os.getenv() The values ​​are set by the values ​​in .env a file. Values ​​can be brought from others dotenvFormat files.
    • WiFi functionality implemented on Raspberry Pi Pico W.
    • Revised Espressif Camera Support, now available on ESP32, ESP32-S2, and ESP32-S3.
    • Combined analog input: analogbufio (Only available in RP2040 at the moment).
    • Pin state can be maintained during deep sleep (only available on Espressif for now).
    • Allow assignment of USB VID, PID, Manufacturer and Product IDs at runtime.
    • maybe collections.deque on most architectures.
    • MP3Decoder And the WaveFile It can now take a file name instead of an open file.
    • AnalogIn Whole values ​​range from 0 to 65535, rather than having zeros in the low-order bits.
    • Firmware update in place (dualbank) may be disabled in favor of a larger CIRCUITPY engine.
    • added TileGrid.contains().
    • added os.utime().
  • added coproc Module, to run programs on a co-processor on the chip. Currently available for RISC-V core on ESP32-S2 and ESP32-S3.

Compatibility changes

  • PulseOut . is no longer accepted PWMOut. use Pin While that.
  • Support auto brightness in . format displayio And the framebufferio It has been removed. It has not been fully implemented.
  • OneWire just in onewireiono longer exists busio or bitbangio.
  • gamepadshift Removed: use keypad.ShiftRegisterKeys While that.
  • Print an integer that floats accurately and correctly.
  • renovate rainbowio And the onewireio for a number of boards. Some boards are still out rainbowio It has been discontinued for space reasons.
  • i2ctarget.I2CTarget is the new name for i2cperipheral.I2CPeripheral. Accept both for now. I2CPeripheral It will be removed in 9.0.0.
  • Property supervisor.runtime.ble_workflow replace supervisor.disable_ble_workflow().
  • Property supervisor.runtime.next_stack_limit replace supervisor.set_next_stack_limit().
  • Property supervisor.runtime.rgb_status_brightness replace supervisor.set_rgb_status_brightness().

port status

CircuitPython contains a number of “ports” that are the primary implementations of the different families of microcontrollers. Stability varies based on each port. As of this release, these ports are considered stable:

  • atmel-samd: Microchip SAMD21, SAMx5x
  • cxd56: Sony Presence
  • espressif: Espressif ESP32-S2
  • nrf: North nRF52840, nRF52833
  • raspberrypi: Raspberry Pi RP2040
  • stm: STM32F4 chipset family

These ports are considered alpha and will contain errors and missing functionality:

  • broadcom: Raspberry Pi boards such as the RPi 4 and RPi Zero 2W
  • espressif: ESP32, ESP32-S3, ESP32-C3
  • litex: fomu
  • mimxrt10xx: NXP i.MX RT10xxx
  • stm: ST chipset families other than STM32F4
