CircuitPython 8.0.0 Beta 2 Released! circuitpython « Adafruit Industries – Makers, Hackers, Artists, Designers, Engineers!

From Github version page:

This is it CircuitPython 8.0.0-beta.2, 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 Raspberry Pi Pico W has changed since version 8.0.0-beta.1. When downloading version 8.0.0-beta.2 via beta 1 (or vice versa), On Picco W onlyCIRCUITPY 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, file editing, and serial/REPL connection.
  • 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.
  • The WiFi function has been implemented on the 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().

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 turned

From 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
