28:57 Status Updates

30:58 @brentru

Lots of work last week with bringing up new boards, testing and verification.
- Brought up two new boards: a pybadge with airlift and the mini pyportal
Added new board pin definitions to arduino-core and the circuit python core, my first core contribution for both circuit python and arduino.
RGBLED v1.0 released: high-level PWM control for your RGB LEDs
This Week:
- Playing with the idea of adding a cursor into the PyPortal library for the airlift pybadge to click buttons instead of touching the screen.
- Looking into Google Cloud’s IoT Core - similar service to Azure IoT but for google cloud services.

@cater (lurking)

32:35 @cgrover

Over the last week, working with range slicer eurorack module, running 2-3x faster with beta CP. Encourage to continue support for high speed display that I’m getting from OLED screens. See OLED support sooner than later, but not bogged down in management things.
Used kjw’s MIDI lib and built a MIDI sniffer - performance is excellent, seeing MIDI data streams using a REPL, great for troubleshooting, classic MIDI.
Updated a MIDI util lib to include a controller description decoder based on MIDI 2.0 - helpful to plug a freq into it and it’ll tell you what note it is and vice versa
Upcoming:
- Releasing final version of lib: hysteresis based map range tool
- Final version of MIDI util lib and will post it along with sniffer as example
- Inspired by John Park project - built prototype MIDI input wing, took that to the extreme and will post it soon

@charlesburnaford (lurking)

35:58 @danh

5x CPU-bound CircuitPython speedup by just changing a VM compile option
Researched further 2x-3x speedup by not calling background tasks as often
Just about done with BLE Scanner
To do: I hope to have a beta of core and BLE library soon, continue further BLE functionality

37:32 @deshipu

Back in the CircuitPython land, looking at displayio again
Got the bouncing balls demo working

39:30 @docmollo (lurking)

Finally got my test environment working at home again woo!
Got the changes that I reviewed with @kattni and @brentru submitted for the ESP32SPI library

@heirophect (lurking)

39:53 @jerryn

Cleaned my office/workspace!! There is now vacant surface area!
Played with PN532 reader in response to a discord question -- I learned a lot!!
- The new “mifare” demo helped a great deal.
Hope to have time to experiment with the ESP32SPI updates and displayio.
- Hope springs eternal….

41:17 @kattni

Last week:
- Worked through possibilities for the Debug_Bus_Device library
- Chose a route and went with it for Debug_Bus_Device
- Friday and over the weekend, worked up code for Noe and Pedro for a definitely-not-a-light-saber light wand.
- Continued work on PyBadger.
- Discussed intent for PyBadger - incidentally more badge focused. Will include all components for simple use, and will also make it super simple to turn your board into a badge with your name on it, etc.
This week:
- Library Monday
  - Sort out a community submitted CircuitPython library to get it into the community bundle
- Finish Debug_Bus_Device
- Continue work on PyBadger.
- Blog posts for PyCon (still, yes)
- Process photos from PyCon (started)
- Forum support
- Update a guide with new pinout diagram
- Test EPD update on 2.13” eink display.

@kingernorth (lurking)

Last Week:
- Cookiecutter-adafruit-circuitpython:
  - Fixed some formatting issues
- RosiePi:
  - Finished the "rosie side" physical-test framework. This allows tests written outside of the core repo to run on the RPi, while controlling the board being tested. sweet log: https://gist.github.com/sommersoft/45a309cc2edee153ef1e21ae4cff2af0
  - Started on RPi config to run RosieApp & RosiePi
  - Researched & defined some architecture details (which DB, Sinatra vs Flask, etc).
- This Week:
  - RosiePi & RosieApp
    - write some actual tests
    - Finish RPi config, and possibly setup an Ansible/Terraform for the config

29:27 @tannewt

Got partial screen updating checked in
4.1.0-beta.0 release
One fix for TileGrid to get in that causes new characters on the terminal to not appear until a new row.
High gear for Teardown prep. Leave on Thursday.

50:34 In the Weeds

51:13 @deshipu Accessing pixels of OnDiskBitmap, converting it to Bitmap.
56:42 @deshipu Limit the framerate on displayio?
1:05:43 @danh: _bleio vs bleio, wrappers vs visible use of bleio
