From the GitHub launch web page:
That is CircuitPython 9.0.0-alpha.6, an alpha launch for 9.0.0. It has important recognized bugs, and could have additional additions and fixes earlier than the ultimate launch of 9.0.0.
NOTE: CircuitPython 9.0.0-alpha.4 and later use a brand new inside dynamic storage mechanism (“break up heap”), which is being tuned. You might discover that some CircuitPython applications fail with MemoryError
. When you encounter applications that work in 8.x.x however get MemoryError
exceptions, think about submitting a difficulty with particulars.
WARNING for nRF52 boards solely: In case your board has an nRF52 UF2 bootloader whose model is earlier than 0.6.1, you will be unable to load CircuitPython 8.2.0 and later, resulting from elevated dimension of the firmware. See these directions for updating your bootloader.
Notable modifications to 9.0.0
- New split-heap inside dynamic storage mechanism.
- Merge updates from MicroPython v1.19.1, v1.20.0, and v1.21.0.
- Espressif: replace to ESP-IDF v5.1.2.
- Reorganize and break up
displayio
. 8.x.x naming construction is obtainable in 9.x.x, however can be eliminated in 10.0.0. - CIRCUITPY drives now mount on Android.
- Elevated file capability on CIRCUITPY drives <= 128kB.
- Additional USB host assist, on i.MX and RP2040.
- Take away 8.x.x deprecations:
displayio.*.present()
,I2CPeripheral
renamed toI2CTarget
. - Add
jpegio
JPEG decoder assist. - Add
repl.py
, which runs simply earlier than the REPL begins up. - Add
OrderedDict.move_to_end()
. - Add
synthio.Synthesizer.note_state
. - Add
warnings
module, comparable to what’s in CPython. - Add
locale.getlocale()
. - Add I2S MCLK assist on Espressif.
- Add mDNS TXT report assist.
- Add
synthio.Be aware
.loop_start
and.loop_end
properties. - Permit signed amplitude in
synthio
.
Obtain from circuitpython.org
Firmware downloads can be found from the downloads web page on circuitpython.org. The location makes it simple to pick the proper file and language in your board.
Set up
To put in observe the directions within the Welcome to CircuitPython! information. To put in the newest libraries, see this web page in that information.
Strive the newest model of the Mu editor for creating and modifying your CircuitPython applications and for straightforward entry to the CircuitPython serial connection (the REPL).
Documentation
Documentation is obtainable in readthedocs.io.
Port standing
CircuitPython has a variety of “ports” which are the core implementations for various microcontroller households. Stability varies on a per-port foundation. As of this launch, these ports are think about steady (however see Recognized Points under):
atmel-samd
: Microchip SAMD21, SAMx5xcxd56
: Sony Spresenseespressif
: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C3nrf
: Nordic nRF52840, nRF52833raspberrypi
: Raspberry Pi RP2040stm
: ST STM32F4 chip household
These ports are thought of alpha and could have bugs and lacking performance:
broadcom
: Raspberry Pi boards similar to RPi 4, RPi Zero 2Wlitex
: fomumimxrt10xx
: NXP i.MX RT10xxxsilabs
: Silicon Labs MG24 householdstm
: ST non-STM32F4 chip households
