Overall: It’s great to see the push to get through the currently open PRs, thank you to Jose David for all the work going into that. It’s also great to see weekly updates to the Community Bundle.

22:02 Status Updates

22:30 @jepler

  • Last week:
    • Built mpy-cross for M1 macs (with quick correction/improvement from community member djix123 on github!)
    • Added Actions CI to verify that most ports can be built on Windows successfully & fixed some bugs
    • Started adapting esp32s2 camera capture code into CircuitPython
      • The code is for the Kaluga with OV2640 but we’re trying to use it with OV7670 since that’s what we have initialization code for
      • The code is not particularly stable (images are artifacty or shifted) on my Kaluga devkits with the official camera :-/ which is worrying
      • Using this code means I don’t have to worry about low level stuff like FIFOs and DMAs though
  • This week:
    • Continuing with esp32s2 camera capture code
    • Have to wire up a custom proto shield, which just takes a long time for me
    • Will know soon if it works or not; hopefully it does work

24:29 @jerryn

  • Still baffled by the tca9548a issue on rp2040
    • Logic analyzer shows that it is not sending commands properly. The channel switch is missing sometimes.
      • No idea why
  • Ran into issue with HCSR04 (RCWL-1601) not working properly on RP2040 - OK in M4 - Opened issue in HCSRO4 but may be a CP (pulsein) issue.
  • In response to a forum post, tried running a Airlift on an Rp2040 Pico running Micropython -- using Blinka
    • MP does not have time.monotonic() -- had to revise library code
    • Ran into an SPI issue - unable to get it working so far.

27:16 @Jose David (missing meeting)

  • Las Week:
    • Reviewing PRs.
    • Working on BME280 and DPS310 Memory optimization
    • Some small docs updates
  • Next Week
    • I will be on PRs land for one more Week.
    • Reviews if needed

27:42 @kattni

  • Last week:
    • Published NeoKey Trinkey guide
    • Started Rotary Trinkey guide
    • Worked with Dylan on starting the move of the libraries from master to main
    • Finished up the Analog In template page
    • Tested a new feature in Learn
  • This week so far:
    • Reviewed DPS310 PR
    • Continued working on Rotary Trinkey guide
    • Final testing of the Learn feature
  • The rest of the week:
    • Finish Rotary Trinkey guide
    • PrettyPins for some SAMD21 boards
    • Factor out Simple Text Display from CLUE library into its own helper library

33:07 @MakerMelissa

  • Last Week:
    • CircuitPython.org board updates
    • Started working on a new learn guide with speech recognition
    • I went through my guide feedback and made updates where applicable
    • I also went through the Google Assistant and eInk Calendar guides and redid the steps for Google Setup on the Calendar guide as they had completely changed.
    • Helped @kattni with adding arduino boards to check when PRs submitted
  • This Week:
    • Working on learn guide for speech recognition
    • Taking a look at some of the Raspberry Pi Shell Scripts

34:00 @tannewt

  • Took Friday and Monday off. Nice long weekend! Made some progress on Fiber Deserts too!
  • Working on BLE workflow.
    • Added different advertisements based on bonding state.
    • Added 1 second wait for enabling BLE.
    • Working on USB/BLE file system sharing. USB will win vs BLE. User code access will follow existing API.
    • Filed an issue with Antonio about multipacket responses crashing. Will try to get them a build this week.
    • Testing all of the components via the test scripts. The original scripts didn’t handle reconnects that the real version has.
  • Taking time off June 10th - 18th. Back on the 21st. No Deep Dive for the two weeks after this one.

36:36 @anecdata (text only)

  • Off-the-grid: no internet for most of the next week or so

36:51 @danh

  • Fixed some dynamic HID bugs encountered by @ATMakersBill.
  • Working on native keypad support for simple keypads and key matrices.
  • Released 6.3.0-rc.0. Will do 6.3.0 final today or tomorrow.
  • PR to raspberrypi/pico-sdk to handle slow clock startup on some RP2040 boards.

38:48 @david.glaude (lurking)

  • CP
    • Just chatting with CGrover about thermal cam (maybe a CP fatigue)
  • Non CP:
    • Successfully used WLED [ESP32 Wifi LED animation] with Neopixel and Dotstar in 5V… but failed with the 12V led strip I did plan to reuse.
    • Playing with Docker on Pi4 with https://sensorsiot.github.io/IOTstack
    • Acquired 3m x 1.4m of reflexive fabric (Green screen trick with LED)

39:40 @foamyguy

  • Last week
    • Implement guest user functionality on designio so that people can make designs without a user account
    • Research consumer codes for brightness and PR to HID library to add them
    • Possibly found a working solution for installing circuitpython-stubs from pip
  • This week
    • Validate stubs install can work from test listing on PyPi. I was able to successfully install it locally. If this works then prepare a repo or whatever will be needed to get ready for deploying them.
    • Write some code for using a rotary encoder to send HID consumer codes.
    • 3D model a phone / tablet stand with a crank arm integrated

  • 41:36 In The Weeds

41:40 @danh

  • Consider dropping settings.py as an alternate name for boot.py. Not used in practice and can be confusing. A user had an innocuous settings.py that was overriding boot.py the first time he tried to use boot.py/
  • Consider dropping boot.txt, code.txt, etc. and also checks for double extensions. Conclusion: Yes, drop support in 7.0

45:27 @jerryn I2C Rotary encoder (and Trinkey, I think) -- there have been several comments about them “going the wrong way” The counts decrease when turned clockwise. Is this an issue or a “feature”

Conclusion: Report as bug in library, but consider whether it is a bug in seesaw as well.

53:24 Wrap-Up
