pybricks/pybricks-micropython v4.0.0b2

4.0.0b2

on GitHub

Fixed

• Enable CI releases for v4.x.

4.0.0b1 (no release with this version because of CI issue)

Added

• Experimental support for USB connectivity on SPIKE Prime (pybricks-micropython#208). Currently disabled by default.
• Initial support for pybricks.iodevices.UARTDevice (support#220).
• Enabled previously hidden support for multiple code
  slots (pybricks-micropython#264, pybricks-micropython#312).
• Added the following status flags to the Pybricks protocol:
  • PBIO_PYBRICKS_STATUS_BATTERY_HIGH_TEMP_SHUTDOWN = 10
  • PBIO_PYBRICKS_STATUS_BATTERY_HIGH_TEMP_WARNING = 11
  • PBIO_PYBRICKS_STATUS_USB_HOST_CONNECTED = 12
• New embedded firmware for LEGO MINDSTORMS EV3:
  • Fast boot on TI AM1808.
  • New clock driver.
  • New display driver.
  • New SPI storage driver.
  • New USB controller.
  • New motor driver.
  • New UART driver with hardware and PRU support.
  • New PRU firmware for LED PWM control.
  • New GPIO driver.
  • New ADC driver.
  • New DCM driver for EV3 auto-detection.
• Enabled the original pybricks.ev3devices to run on the new embedded EV3 port:
  • Color Sensor.
  • Touch Sensor.
  • Infrared Sensor and Beacon.
  • Gyro Sensor in angle + rate mode, with calibration option.
  • Ultrasonic Sensor.
  • Large and Medium Motor.
• Enabled the original pybricks.nxtdevices to run on the new embedded EV3 port:
  • Touch Sensor, including 1.0 version without auto-detection.
  • Color Sensor, with background process for background light cancellation.
  • Light Sensor, with background process for background light cancellation.
  • Ultrasonic Sensor, including I2C quirks for LEGO Devices.
  • Sound Sensor.
  • Temperature Sensor in I2C mode.
  • Energy Meter.
  • vernier Adapter.
• Enabled all original pybricks.iodevices, all async-compatible:
  • PUPDevice / LUMPDevice on Powered Up and EV3.
  • AnalogSensor on EV3.
  • I2CDevice on EV3.
  • UARTDevice on EV3 and Powered Up. Added ability to reset protocol.
  • DCMotor on EV3
• Added new pbio/image module for image frame handling and display support.
• Added a new Virtual Hub to simulate the embedded Pybricks ports.

Changed

• Extensive overhaul of UART drivers on all hubs. This affects all
  official LEGO UART sensors on all hubs.
• Extensive overhaul of the pbio/port module. LEGO mode can now be disabled
  to enable direct access to UART or I2C or ADC on compatible platforms.
• Extensive overhaul of MicroPython async drivers to make it work across
  Bluetooth drivers.
• Extensive overhaul of Bluetooth drivers to split out common code and make
  async code more stable and safely cancellable.
• Overhaul of Bluetooth and USB events through a unified pbio/sys/host interface.
• LWP3Device.read() now gives buffered notification values instead of blocking
  until a value arrives.
• Replaced Contiki runloop with new Pybricks protothreads.
• Enabled flto for smaller firmware build size.
• Upgraded to MicroPython 1.26. The MPY minor version has changed to v6.3.
  This only affects people using native code in their user programs.
• Update NXT build to follow along with EV3 wherever possible.
• Unified mphalport and micropython.c interface for all hubs.
• Improved power-off sequence to better handle sensors turning off and internal
  devices like the IMU turning off.
• Restored line numbers in error messages on Move Hub
• Enabled CSUPEROPT on Move Hub and Technic Hub to reduce build size at a
  slight reduction in VM speed.

Fixed

• Reduced hanging when broadcasting and observing at the same time with Technic
  Hub (support#2206).
• Fixed hub shutting down immediately after disconnecting Bluetooth when
  no program had run for a while.
• Fixed some error messages not printing on a new line if a program ends.
• Fix speaker when playing a frequency of 0.
• pybricks.tools: Fix crash when cross() args are wrong type.

Removed

• Removed support for Pybricks on ev3dev. The official 2.0 release remains
  available for anyone who needs Pybricks on Debian Linux.
• Removed the experimental build of Pybricks on EV3RT. This is no longer needed
  now that the embedded build is ready.
• Removed unix-variant of the Virtual Hub. This has been replaced with a simulated
  embedded hub.
