This is CircuitPython 7.0.0-rc.3, a release candidate for CircuitPython 7.0.0 final. We have addressed all the issues we scheduled for the 7.0.0 release. This release fixes an RP2040 regression introduced in 7.0.0-rc.2. We believe this release is stable, but want to give time for further testing.
Notable additions to 7.0.0 since 6.3.0 include:
- Support for the CircuitPython development workflow over BLE.
- Camera support on ESP32S2.
qrio
: QR code decoding.- The
keypad
key-scanning module. - Run-time customization of USB devices.
- Merging in of MicroPython fixes and enhancements as of MicroPython 1.16.
_pixelbuf
is nowadafruit_pixelbuf
.colorwheel()
routine moved torainbowio
.supervisor.ticks_ms()
to allow easier time-keeping.- Simplifications to the RGB status LED codes.
- A clocking fix for a few samples of RP2040 boards.
- Rework of
vectorio
and some of its API.VectorShape
is no longer needed for user code. atexit
module.getpass
module.traceback
module.supervisor.get_previous_traceback()
.board.LED
now consistently present on all boards that have such an LED.PulseOut
no longer needs aPWMOut
.- Unicode filename support.
- Board ID is now in
boot_out.txt
and available asboard.board_id
. aesio
on for full builds by default.
Download from circuitpython.org
Firmware downloads are available from the downloads page on circuitpython.org. The site makes it easy to select the correct file and language for your board.
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).
Port status
CircuitPython has a number of “ports” that are the core implementations for different microcontroller families. Stability varies on a per-port basis. As of this release, atmel-samd
, cxd56
(Spresense), esp32s2
, nrf
,raspberrypi
, stm
for the F4 family are stable. stm
for other STM chip families is being actively improved but may be missing functionality and have bugs. litex
and mimxrt10xx
are in an alpha state and will have bugs and missing functionality.
Changes since 7.0.0-rc.2
