9:52 State of CircuitPython, Libraries and Blinka

10:16 Overall

  • 19 pull requests merged
    • 17 authors - weblate, dhalbert, WarriorOfWire, 2bndy5, makermelissa, phil-shenk, kmatch98, dherrada, bergdahl, NathanBnm, wtuemura, cwalther, jepler, ryevertigo, fede2cr, hathach, joeycastillo
    • 7 reviewers - tannewt, brentru, jepler, dhalbert, deshipu, ladyada, makermelissa
  • 10 closed issues by 5 people, 18 opened by 17 people

Overall: We’re towards the tail end of the 6.0 development. It’s very exciting. Our library count continues to grow despite the fact that we thought we were done with everything. I’m seeing more and more people use Blinka as well, so libraries are even bigger than CircuitPython itself. Credit to Melissa and Kattni for leading those efforts.

30:21 Status Updates

31:29 @tannewt

  • Making progress on native Wifi API. Wrote logic for scanning and now debugging it. Ran into issues with RAM linking and also the partition size once everything was linked in.
  • The scanning logic now executes without crashing but doesn’t return any results. Suspect I need to configure the wifi before starting it.
  • Focussing on getting wifi set.
  • Slowly making FPGA progress in my spare time.
  • Taking Friday off to get outside on a hike.

  • Yet more work on _bleio HCI. I now have a complete mental picture of the multiple protocols involved, and am writing more code. Now debugging service discovery.
  • Mpy-cross executables are now uploaded to S3 on every build. Thanks @jepler for help.
  • Also with @jepler, squeezed some overflowing builds to make them fit.
  • Fix one cause of Linux crashing when CircuitPython resets.
  • Updated circup for new bundles.
  • To do:
    • Continue on _bleio HCI.
    • Re-test Bluetooth pulse oximeter (though it seems to be OK).

@dave p (lurking)

36:40 @David.Glaude (lurking)

  • Sorry, lost track, not enough time to prepare this meeting…
  • Found that step tracker was missing from CLUE library and reported with an issue.
  • Wanted to change @UnexpectedMaker ESP32S2 board image with a dark one but did not find the time to do it. (actually I wanted all board images to be with dark background as my new screen was set to super bright)

@deshipu (lurking)

37:11 @dherrada Last week

  • Finished astrophotography tracker
  • Designing a 60% mechanical keyboard that uses a feather board

This week

@duewester (lurking)

37:56 @fede2 Last week

  • Translating CircuitPython Library
  • Testing @hierophect’s neopixel PR
  • Commissioning the creation of Quetzalblinka This week
  • Translating the CPX product guide
  • Learning how to add PSRAM support for the ESP32-S2. @tannewt, all offered help if now extra-welcome
  • Creating a website for CircuitPython day Centralamerica/spanish
  • If no objections, modify jekyll to accommodate translations for circuitpython.org (in the weeds)

39:16 @foamyguy Last week

  • Found and fixed an issue stemming from the recent ProgressBar update.
  • Impulse bought Seeed Wio Terminal and Xiao. Surprised with how fast they arrived. Got Circuit Python flashed on them and Win7 USB drivers sorted out.
  • Got back to work on my JSON Layout system for displayio. Added ProgressBar and the new Sparkline shape and refactored to only import views as needed.
  • Found a fix for CLUE sensor project that was running out of memory after recent display_text changes.
  • Learned how to use cookiecutter and started creating VectorProgressBar library. This week
  • Fix a few remaining CI issues with VectorProgressBar and look into submitting it for the Community Bundle
  • Testing the bitmap_label
  • Investigate logger template string replacement issue in circup

42:31 @hierophect

  • Last week
    • Mostly worked on the Neopixel and the PulseIn/PulseOut implementation
  • This week
    • Work on PulseIn and PulseOut for the ESP32-S2
    • Switching over to F1 Flash briefly to get that unblocked, maybe? I can’t find any good dev boards for it and it’s making me question the endeavor.
  • Fun stuff
    • Made a flashcard app on the Open Book using Json. It was neat to be able to build and test an application on my host computer, and then move it over to Circuitpython without much effort. Kudos to Joey who created the Babel translation flash image that makes true unicode support possible on Circuitpython.

@JacobT (lurking)

45:49 @jepler

  • Last week:
    • New guide covering the SDIO & SPI breakout board as well as the new SD card functionality in 6.0 alpha releases.
    • Moving a number of PRs towards mergeability
    • Enabling framebufferio displays to be coded in pure Python, purpose: sharp memory display support
  • This week:
    • TBD - depends how the framebufferio changes are received. Either changing approach to do Memory Displays fully in core, or upstreaming the library changes that make the Memory Displays work with framebufferio
    • Maybe figuring out how ardupy enables C++ libs
  • Fun stuff:
    • Sent off a PCB for manufacture. Si5351 Frequency synthesizer with external reference input and Trinket for control/setup. Now I have to wait for Trinkets to come back in stock! (as well as for the PCB)

48:17 @jerryn

  • Found and reported an issue with PulseIn for M0 boards
    • PR by @DavePutz is in, but is not working for me yet
  • Trying to test @hierophect neopixel PR for esp32s2 but my builds with it won’t boot. Not sure why. Seems to work for others.
  • Submitted PR to update frozen Libraries
  • Testing gcc10 for CP build
    • Seems to break SAMD51 boards …. OK on SAMD21
      • Has anyone tested a SAMD51 uf2 built with gcc10?
    • Built gcc10 arm toolchain for Raspberry Pi -- I can provide a tarball if anyone wants it.

51:12 @kattni

  • Last week:
    • Recruited some new CircuitPython Helpers following up recruiting one of two of them into Community Moderators.
    • Helped @anecdata with formatting a very well written message full of great CircuitPython getting started links and info for me to pin in the #help-with-circuitpython channel on Discord
    • Helped @fede2 with a guide issue - turns out it’s by design, no solution for now
    • Created three new fritzing objects including the Grand Central M4 which is the most complicated one I’ve ever done and of course it was full of weird problems because why not
    • Updated the BME680 guide to feature the STEMMA QT version of the board
  • This week:
    • Update 0.96” 128x64 OLED graphic display with STEMMA QT version

53:25 @kingernorth (text only)

  • Last week I did another live stream on my youtube channel for my show Micro-controllers with kingernorth and the topic was Trinket M0 with CircuitPython and Arduino, https://youtu.be/ELXsPOX9-MU
  • This week I’m working on a couple of projects for my model railroad layout for an automated turntable and a weight scale for my mine.
  • Also this week I’m setting up a course for the local college for a fully on-line Arduino programming course using the Adafruit MetroX kit. CircuitPython courses are coming later.

54:07 @kmatch98

  • Mostly done with display_text ‘bitmap_label’ alternate for ‘label’ to reduce memory for large amounts of text

@Mr. Certainly [lurking]

55:37 In The Weeds

@fede2

  • 55:54 Is it ok if I add translations support and start a spanish translation of the circuitpython.org site? @danh says it’s ok, and that he’d like to have a lang selector, so that the visitor can move between translations.
    • @kattni - Yes - already contacted Justin with how we’ll get started.
  • 57:45 The Wio Terminal jumped in the downloads sorting which is based on download-for-dev-count. Why did it happen so fast? Is the circuitpythonistas-to-be number from CN so big? Mandarin translations? Other big hw vendors we should extend a hand to?

1:01:38 @jepler - non-circuitpython community meeting? Mods & helpers meeting? Other ways that the community needs to connect
