@foamyguy (hosting)

@Tyeth for researching some python inheritance specifics about how to call a “grandparent” super init function instead of the “parent” like usual.
@MakerMelissa welcome back, and thank you for adding many 3rd party board how-to links to circuitpython.org
@GordieGii for pointing out the cause of a visual issue I was seeing during stream

18:34 @danh

@foamyguy for working on the backlog of CircuitPython library PR’s and issues.
@melissa - great to have you back

19:10 @jepler

Group hug
Hug to Melissa, happy to see you are picking up some CircuitPython & Blinka work again.
@foamyguy for fixing a bitmap label bug I ran into awhile back (as well as a ton of other issues!!!)
This week marks 5 years since I made Adafruit my primary work and I’m really grateful for all the time I’ve had in this wonderful community, learning how to do all sorts of things.

19:47 @Liz (likely notes only)

Melissa - welcome back 🎉
Jeff for reviewing a Learn repo PR that involved looking at a recent refactor in FastLED that was causing CI to break

20:09 Status Updates

Refactored and cleaned up TextBox widget & submitted PR
Add a FilledPolygon class to Display_Shapes library and made both it and the existing Polygon class support stroke argument for the size of the outline like all the other shapes do.
Internal refactor inside i2c._send() function in BlinkaDisplayio that was suggested in an issue. It resolves an issue resulting in sleep() and wake() not working for SSD1306 and SH1106 displays
Rotation fix in SH1107 for 90 degree offset when setting rotation after init
Display_Text fix to error about incorrect arguments & fix for BitmapLabel ascenders and descenders
Added LinearLayout to Displayio_Layout library

24:19 @danh

I fixed a problem with I2CTarget not working after a soft restart.
CircuitMatter: I couldn’t find a straightforward replacement for ecdsa library among other available elliptic curve libraries. Now I’m reading the spec and the code to figure out what capabilities are needed.

26:00 @jepler

I’ve been working in the Arduino environment on floppy emulation.
- Current task is to get “FM” data modulation working
- Xerox 820 CPM computer doesn’t like the data I’m producing .. yet.
- It looks like I might be producing an incorrect sector header but I don’t know why yet
Small things in the circuitpython world such as code reviews
