    • Fix more 10.0.0 issues.
    • Change more 4MB ESP32-S3 boards to larger partitions: TFT, reverse TFT, QT Py.

16:50 @foamyguy

  • Triage some issues reported with new versions of Blinka and submit some fixes
  • Fruit Jam OS
    • Actions for daily release check and making a new release automatically
    • Launcher enhancements: fixed mouse click on page arrow buttons, add hotkeys for going to different pages, allow user to disable mouse with a config file

19:40 @tekktrik (not present)

  • Trying to help out with PR reviews as I have time
  • Planning a CoAP library that will add some standard IoT communication options, particularly helpful for communication over UDP or LoRa.

20:45 In The Weeds

21:17 @tekktrik (not present)

  • There was some discussion around moving away from “dynamic” requirements (requirements.txt) and moving towards more static ones (within pyproject.toml). This would allow folks using tools like “uv” to have dependency management work right out of the box.
    • I believe this is possible using some of the tools within Adabot, and I’m happy to do this.
    • I don’t think any libraries actually require dynamic requirements, so the technical risk is very low.
  • 28:00 If “gpiod” is not installed with Blinka while using generic Linux, it throws an ImportError that this was not done. However, due to the try/except we use for type annotations, we catch and then silently pass this error if we ever have using digitalio.DigitalInOut within type annotations for a library. This causes issues on SBCs that require type annotations to truly exist at runtime. [See https://github.com/adafruit/Adafruit_CircuitPython_BusDevice/pull/102]
    • We could change the warning exception in Blinka away from ImportError, but it really IS an import error. An alternative candidate could be OSError, since it relates to the pins.
    • We could go and patch the other libraries as well to make definitions/values exist at runtime. This was the proposed solution for the instance where this issue was identified.

38:05 Wrap-Up

Next meeting is Monday, June 30, 2025, at the regular time of 2pm US ET / 11 am US PT. After that we’re planning to go to a bi-weekly schedule for July and August.
