19:17 Status Updates

32:35 @brentr Last Week:

New Module: CircuitPython Azure IoT Module - connect your circuitpython device to a Microsoft Azure IoT Hub. Lots of possibilities when you integrate this with Azure’s services like machine learning, data analytics, etc.
- https://github.com/adafruit/Adafruit_CircuitPython_AzureIoT/
New Guide: Azure IoT with CircuitPython to make a plant monitor
- https://learn.adafruit.com/using-microsoft-azure-iot-with-circuitpython
Non-CircuitPython: The ESP8266 now works with Adafruit IO Arduino without downgrading firmware anymore. This Week:
Building out a CircuitPython library for the ATECC608 cryptographic coprocessor.
- End goal would be generating a CSR, usable by AzureIoT or maybe Adafruit IO in the future.
- faster/more secure circuitpython IoT - even with CircuitPython_TinyLoRa.

@CGrover (LURKING)

@charlesburnaford (LURKING)

34:15 @danh

Fixed HID library issue preventing negative mouse movements due to stricter CircuitPython bytearray value checking.
Updating frozen libraries to update HID and other libraries.
Added mechanism for per-language clean builds, needed for large translations.
Moving BLE advertising data preparation to Python from C.
Support work for bootloader problems.
To do:
- Continue BLE work.
- CIrcuitPython variants refactoring: Maybe add flags to distinguish 192KB, 256KB, and full builds. Update documentation to match.

37:03 @docmollo (lurking)

Based on code review with @kattni on the ESP32SPI library, going to refactor the connect() function into two functions. Due to work and the holiday this weekend, didn’t have time, so will be at least a week or two before I finish all the updates I’m working on.

37:26 @jerryn (LURKING)

Back from travels - still trying to remember what I was doing before I left.
Should be re-engaged this week.

37:37 @joseph

Last couple of days: Atom Plugin
This week: Holidays, time to revise
Last couple of weeks: Exams
Next couple of weeks: More exams
After that: Summer holidays! Plenty of time to write all sorts of code.

19:57 @kattni

Last week:
- PyGamer guide
- PyGamer fritzing object
- Moved!
This week:

22:51 @MakerMelissa:

Last Week
- Typed up my notes for PyCon
- Worked on displaying fonts in more complicated language fonts
- Got my PyBadge Conference Badge guide in moderation
- Finished updating the SSD1331 guide
- Added a couple small image updates to SSD1351 guide
- Added enableDisplay() to ST77xx Arduino Library
- Tested similar functionality on HX8357 Display with Backlight

@Roy (LURKING)

24:56 @siddacious:

Previously on Law & Order:
- Finished up version 1.0 of BD34 CP and Arduino drivers
- Sent out a board rev for the BD34
- Sent out a board to test a new OLED
- Finished the LPS34HW guide
- Wrote tester code for and designed the tester for the LPS35HW
Next time on “siddacious does stuff”
- Neopixel connector widgets
- BD34 rev be assembly and driver work
- OLED testing
- Miscellaneous board, driver, and support work.
- Going to NY for the Five Points Festival with my wife, stopping by HQ to say hi

27:00 @sommersoft

Last Week:
- Circuitpython-build-tools:
  - Fixed PyPI deployment issue (that i created).
- Adabot:
  - Fixed the non-.py file "missing sensorname" validator. However, there are still some inconsistencies that aren't easily fixed on the repo side:
    - Multi-version libraries: e.g. adafruit_ads1x15 has simpletests for different variants. I think the variants are a good thing. I can probably work around it with some regex + slicing…
  - Dove into the "release notes documenting proper contributor" issue. Walking the code step by step in a terminal, it produces desired results.
  - The issue may have been a one-off, but I can't explain it. Left the issue open for continued monitoring.
- Experiment: RosiePi
  - Realized I was essentially re-creating the wheel, once I investigated tests/ & tools/cpboard.py in the core. It was still a fun little exercise.
  - I may move forward with it, but need to decide if it should live in the core vs external. My overall goal was to include physical testing, which is still not a thing:
    - simple example: does board.Dn set to digitalio->OUT/IN actually produce expected behavior, as confirmed by say a MCP3008.
    - super-duper-optimistic example: does displayio produce the expected image as verified by a PiCam & OpenCV/tesseractOCR/etc.
This Week:
- Experiment: RosiePi
  - Study current testing in the core, and try to formulate an approach to use on a RPi and expand CircuitPython's usage to physical testing.
  - Look into writing a GitHub App for this. Seems simple enough; just need to work through the Ruby bits. if running this during PR checks would be desired, of course. otherwise...just for fun.

@TG-Techie:

Last week of school, time to relax with some CP
Fixes pure CP tricorder that was broken, convinced a friend to try a board
Figuring out display rotation with locations of objects on the screen
