4.0.0 is the latest major revision of CircuitPython and features support for the nRF52840 BLE chipset, display support and translated messages.

Alpha!

This is the first alpha release of 4.0.0. Alpha releases do not have the complete API from 3.x on the nRF builds and are only meant for testing. (Beta release will have the full existing API but still need work.) Please use the latest stable release when first starting with CircuitPython. It is stable.

When you find a bug please check the current known issues and file an issue if something isn't already known.

Installation

To install follow the instructions in our new 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).

Most builds are available as both UF2 and bin files here along with test builds.

This is the a bug fix and minor feature release for the 3.x stable series. There are a few important fixes and some additions to busio.UART. Please check out the 3.0.0 release notes for full details on what's new in 3.0.0.

Changes since 3.0.1

  • Adjust neopixel write timings on the M4: On-board NeoPixel stopped working on M4 boards in 3.0.1. Thanks to @jerryneedell for the fix and testing, and @ash0x1b for the issue.
  • Handle USB output buffer >255 characters. Thanks @daguitarguy for the issue, initially noticed in the REPL, and thanks @dhalbert for the fix.
  • Allocate PWMOut timer channels correctly. Previously some TCC timer channels were being incorrectly reused in multiple PWMOut objects. Thanks @deshipu for the issue and @dhalbert for the fix.
  • When UART timeout of zero is given, make UART.read() return available data. Thanks to @PaulKierstead for the fix.
  • Re-initialize default board busses on soft reset (board.SPI, board.I2C, board.UART). Thanks @dhalbert.
  • Add UART.in_waiting and UART.reset_input_buffer(), which mirror functionality in PySerial. Thanks @dhalbert, and thanks to @ladyada for the suggestions.

3.0.0 is the latest major revision of CircuitPython and features new support for the SAMD51 (aka M4) and preliminary support for the nRF52 BLE chipset. It also features better memory utilization so more can be loaded in the same amount of space.

General release

We believe this release is stable and relatively bug free. So, please try this before trying 2.x. If you find issues please file an issue.

New Features in 3.0.0

Breaking Changes!

  • ustruct has been replaced with struct to match CPython.
  • ucollections has been replaced with collections to match CPython. Thanks @bildzeitung.
  • ubinascii is renamed binascii to match CPython. Thanks @jepler
  • The mpy format has changed so make sure and use a 3.0.0 bundle for libraries.
  • Non-standard array types inherited from MicroPython are no longer supported in favor of matching CPython. Thanks to @jepler.
  • audioio.AudioOut now takes the sample to playback in play rather than in the constructor. (This enables playback through other outputs such as audiobusio.I2SOut.) It also means you only need one AudioOut for multiple samples.
  • PDMIn's frequency property has been renamed to sample_rate.
  • Trinket M0 and Gemma M0 builds no longer include pin objects for all microcontroller pins. They only include those used by the board. Thanks to @rhooper
  • Auto-reload no longer uses KeyboardInterruptException but rather its own ReloadException. Thanks to @rhooper

CircuitPython 2.3.1 fixes a regression introduced in 2.3.0: if boot.py changed the root filesystem permission to read/write using storage.remount(), that permission change would get undone. This bug would prevent some data logging code from working, for instance.

All other changes introduced in 2.3.0 are still present: battery power fix, storage.erase_filesystem(), and new frozen libraries for Circuit Playground express. Refer to the 2.3.0 release for details.
