CircuitPython 8.0.0 Beta 5 release! circuitpython «Adafruit Industries – Makers, Hackers, Artists, Designers & Engineers!

From Github release page:

This is it CircuitPython 8.0.0-beta.5, beta version for 8.0.0. It’s relatively stable, but there will be more additions, fixes, and changes before the final release.

warning: Flash partitioning for ESP32 and ESP32-C3 boards has changed to 2MB and 4MB for ESP32-C3 boards since version 8.0.0-beta.2. When 8.0.0-beta.3 or later is loaded via beta 2 (or vice versa), onto these boards, CIRCUITPY will be erased and reformatted.

warning: Flash partitioning for Raspberry Pi Pico W has been changed since version 8.0.0-beta.1. When loading 8.0.0-beta.2 or later over beta.1 (or vice versa), on a Pico W, CIRCUITPY will be erased and reformatted.

Notable changes to 8.0.0 since 7.3.0

Job Additions

  • Added WiFi workflow with browser-based device detection, file system browsing, upload, download, file editing, serial connection/REPL (available on Espressif, and as of 8.0.0-beta.5, Pi Pico W).
  • A one-line status bar has been added, which displays connection status, recent exception, and version on the terminal window title or on the top line of the attached screen. Mu 1.2.0 and Thonny 4.0.x and later are able to suppress status bar information in REPL output.
  • .env or not Circle Defines WiFI connection parameters, BLE name, and other startup values.
  • dotenv the support: os.getenv() The values ​​are set by values ​​in .env a file. Values ​​can be fetched from others dotenvFormatting 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 at the moment).
  • Allow USB VID, PID, manufacturer and product IDs to be set at runtime.
  • maybe collections.deque on most builds.
  • MP3Decoder And the WaveFile It can now take a filename instead of an open file.
  • AnalogIn Whole values ​​range from 0 to 65535, rather than having zeros in the lower-order bits.
  • firmware update in place (dualbank) may be disabled in favor of a larger circuitpy drive.
  • added TileGrid.contains().
  • added os.utime().
  • added coproc Module, to run programs on a co-processor on a chip. Currently available for RISC-V core on ESP32-S2 and ESP32-S3.
  • A serial “break” on a serial USB or UART REPL connection will cause a KeyboardInterrupt, such as ctrl-C. The advantage over ctrl-C is that the separator cuts even if the input buffer is full.
  • Add hidden property for vectorio Shapes.
  • add original _pixelmap.PixelMap Support for speed.
  • Chained exceptions are now being executed.

Compatibility changes

  • PulseOut A is no longer accepted PWMOut. use Pin While that.
  • Auto brightness support in displayio And the framebufferio has been removed. It has not been fully implemented.
  • OneWire just in onewireioand no longer exists busio or bitbangio.
  • gamepadshift Removed: use keypad.ShiftRegisterKeys While that.
  • Print an integer that floats exactly and correctly.
  • repair rainbowio And the onewireio for a number of councils. Some boards are still out rainbowio Discontinued for space reasons.
  • i2ctarget.I2CTarget is the new name for i2cperipheral.I2CPeripheral. Accept both for now. I2CPeripheral It is deprecated and will be removed in 9.0.0.
  • Allow display.root_group to be set, rather than using display.show(). display.show() It is deprecated and 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 has a number of “ports” that are core implementations for different families of microcontrollers. Stability varies on a per port basis. As of this release, these ports are considered stable:

  • atmel-samdMicrochip: SAMD21, SAMx5x
  • cxd56: Sony Spearsence
  • espressif: Expressif ESP32-S2
  • nrf: Nordic 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
