I launched CircuitPython 9.1.1 final week to repair an issue with the show backlight not illuminating on SAMD51 boards just like the PyPortal. The discharge additionally features a few different fixes.
I’m persevering with to repair bugs within the 9.1.x milestone and I’m additionally persevering with the merge from MicroPython v1.22.
Melissa
This previous week I arrange a beta web site for code.circuitpython.org. The URL for the brand new website is https://code-beta.circuitpython.org if you want to provide it a strive. At the moment although, it incorporates the identical code as code.circuitpython.org, however the plan is to push modifications there first to keep away from breaking code.circuitpython.org.
Tim
I’ve been engaged on fixing a number of displayio driver libraries that are compatible difficulty with the newest model of Blinka_Displayio. I’ve additionally began switching library repos to make use of Ruff as an alternative of pylint and Black. I’m making that swap on libraries as I come throughout them reviewing different modifications or engaged on different issues. I chased down a problem with SAMD51 gadgets which have built-in shows to search out the precise commit the place the issues started.
Jeff
This week my work so as to add help for IPv6 on most Espressif boards was merged into to the very newest variations of CircuitPython. For now, the documentation is shoe-horned into the “Web Take a look at” web page on Be taught. The tl;dr is: wifi.radio.start_dhcp_server(ipv6=True) after which create sockets with AF_INET6.
Libraries that construct on socketpool, like adafruit_requests and adafruit_ntp would require their very own updates to work with IPv6, as a result of they at all times request IPv4 sockets by way of AF_INET.
You received’t see any updates from me over the following few weeks, as I’m taking a trip!
Scott
This week I’ve continued engaged on CircuitMatter. I’ve reconnected issues to the community and have efficiently replied to the controller! The following activity is to implement the cryptography capabilities used to ascertain a safe message channel. I’m testing with a check controller on my desktop now and may report and replay packets on the Python system aspect.
Liz
This week I labored on a enjoyable undertaking with the Ruiz brothers to showcase BLE on ESP32-S3: the ESP32-S3 BLE iOS Media Controller. This undertaking makes use of an ESP32-S3 Feather with a TFT FeatherWing to show and management Apple Media providers over BLE.
I additionally labored on two product guides. The primary was the CH334F USB Hub Breakout. This breakout permits you to simply construct a customized USB hub, no code required. The second was for the USB Sort C Energy Supply Switchable Breakout. This board is a remix of the unique HUSB238 breakout within the store. This model options DIP switches to pick out the PD voltage as an alternative of solder jumpers. Engaged on the unique breakout bought me very fascinated by bizarre USB energy strategies so I’m excited to have a model that doesn’t require soldering.
