## 14:39 Status Updates
15:02 @Liz (host)
* I’ve been working with U2IF firmware and Blinka. U2IF lets you use RP2040 boards with Blinka and CPython. Carter has done a lot of work with this previously and added a few Adafruit boards. I just added the upcoming ThinkInk Feather and will be adding other RP2040 “bones” feathers
* Related, I attempted to add support for the 7 color eink displays to the CircuitPython_EPD library. I have it refreshing but only displaying in black and white, no colors yet and the resolution seems off so definitely still a work in progress
16:14 @CGrover(text only)
* Continued to exercise `bitmaptools` for improving the Precision VCO’s graphical UI. Finally broke out of sandbox mode and will be wrapping up the prototype soon. Found two PCB changes that will be needed as a result and having an internal debate about choosing purple or after-dark OSHPark boards. A happy dilemma.
* Spending some time today creating a small memory footprint version of the original PyGamer/PyBadge Thermal Camera. Should be fairly straightforward (famous last words).
* Also researching a recently discovered issue with 8.0.5 and display_text not recognizing the width of a space character in a .bdf font and throwing an error. Will run some more tests and submit an issue if it turns out to be other than a cockpit error.
* Found a bunch of “nails” around the house and yard needing the pressure washer “hammer” yesterday. Trigger hand is a little sore today.
17:11 @danh
* Scott and I will triage the 8.1.0 and 8.x.x issues sometime soon.
* BNO055 on i.MX RT1011 fails easily, despite RT1011 claiming that it supports clock stretching. Works fine on RP2040, SAMD, etc. Lots of discussion about this in the Teensy Forums, with maybe somewhat hackish fixes. Paul S. says the BNO055 disobeys I2C protocol in certain ways. The Teensy code is at the register level, not the NXP SDK. I have Saleae traces but need to study them in more detail. To-do: add workarounds to BNO055 library (and other similar libraries).
@david.glaude: (not present)
* nothing yet
18:40 @DJDevon3 (text only)
* It was really neat to see a lot of people participating to help figure out the Alphanumeric backpack I2C issue after last week's “in the weeds” topic. @Danh did a fantastic job troubleshooting the electronic circuit and helping to get I2C working. The culprit was initially hidden because I was using the ESP32-S2 which has an on-board pull-up just enough to pull-up 1 backpack but not both. I switched to the RP2040 Feather and the issue using I2C.scan() became more obvious, the pull-ups on the backpacks simply weren’t working. A bodge wire from VDD to VIO is all that was required. I would have never figured that out on my own.
* A small batch of new LED boards arrived I designed called “Bleeding Rainbow”. It’s a NeoPixel stick made of 50 WS2812C RGB LED’s from Worldsemi. They’re tiny 2mm LED’s and the smallest I could find with a built-in LED driver..
* Only red works at 3.3V, they require 5V for RGB. Thanks to Anecdata for helping to figure it out. I’m happy to report they work great with Circuit Python and the board is cool to the touch after hours of running. You can use 1 on USB power but not 2. Windows threw an error about exceeding the USB power rating and shut off access to my feather completely. Power hungry little things! It removed the Feather from Windows and no amount of power cycling helped.. I had to use Device Cleanup and reboot the PC to get the feather to show up again. With an external 5V power supply they will be replacing the Neopixel strips inside my Mail Boombox.
* House I moved into last year had an old gooseneck faucet probably original to the house. It broke and sprayed water 5 feet into the air. Replaced it with a modern one that has a detachable head. No leaks so far.
20:25 @foamyguy
* Lighter than usual circuitpython workload. Still been working on swapping PC hardware components and ended up opting to set up a new OS instance after failing to get my old one to boot.
* Looking into issues with using 2 displays with displayio. PR’d a fix for an issue that was caused by recent displayio API change. Still chasing some other more subtle issues that are leading to hard crashes on the Monster M4sk
* Updates to the con badge / snake game developed last year for PyCon, adding capability to launch arbitrary external script files defined by the user.
* Catching up community bundle PRs that needed merges from main.
22:39 @kattni
* Wrapping up the RFM69 guide.
* Essentials pages.
* RFM69 basic demo page
* Starting the RFM95 guide.
* Same as RFM69, except for the physical radio module (so, images), and the software
* Wrapping up anything else needed.
* Prepping for PyCon! (some of the things, in no particular order)
* PyBadge badge case and software
* Gathering hardware etc. for Open Spaces and Sprints
* Test my recording setup
* Write my talk for the Education Summit
* Whatever else more
25:37 @tannewt
* Burned out on iMX RT with the 1015. Also realized I probably can’t do XIP mode because we need to escape it to do erase and write.
* Got my DVI feather and started down that journey. Made pretty good progress but it doesn’t work. Need to break out the debugger and/or printfs.
* Speaking of not working, woke my desktop up last night to find the root fs had gone into read-only mode! Boots all the way to the desktop but nothing works with it readonly. Will spend today recovering to another drive and hopefully not losing too much. (Feather DVI code was pushed to github on friday.)
27:52 @tekktrik (not present)
* Last week
* Finished up some Arduino things, and now resuming all my CircuitPython work that was on temporary hold
* This week
* Catching up on some PR reviews
* Prototyping how the rp2040js CI will work
* Looking at some Adabot upgrades/patches that were identified a while ago
## 28:16 In The Weeds
28:36 @tannewt
* Workflows after deep sleep. Should the wifi workflow start again?
* https://github.com/adafruit/circuitpython/pull/7814#issuecomment-1494739035
* https://forums.adafruit.com/viewtopic.php?p=967515#p967515
* Default behavior should be off. We should add a switch to boot.py to allow it to be enabled.
36:19 @kattni
* PyCon 2023!
## 41:39 Wrap-Up
