### 04:04 A CircuitPython Pull Request to Add Split Screen Capabilities
kmatch98 has a new PR in (#5954) that exposes the CircuitPython REPL's display group elements, allowing relocation of the REPL and making things like split screens possible without breaking the existing displayio structure - [Twitter](https://twitter.com/CycleMatch/status/1488370312492326918?s=20&t=n-MDQEFS8XHUjtxEpAiVxQ) and [GitHub](https://github.com/adafruit/circuitpython/pull/5954).

With Piku you can make creating a CircuitPython project, installing packages, deploying, and connecting to a CircuitPython device easy to do from the command line - [Adafruit Forums](https://forums.adafruit.com/viewtopic.php?f=60&t=188036), [PyPI](https://pypi.org/project/piku/) and [GitHub](https://github.com/mraleson/piku).
### 05:10 CircuitPython2022 Wraps Up - Thank You
Scott posts: "[Thank you](https://blog.adafruit.com/2022/02/01/thank-you-for-circuitpython2022/) to the 24 folks who posted for #CircuitPython2022! Thank you for all of the different ideas. I hope that folks collaborate to make these ideas a reality. Thank you to those whose ideas have been guiding principles over the years. We wouldn’t be here without you."
"As Kattni points out in [her #CircuitPython2022 post](https://blog.adafruit.com/2022/02/01/the-circuitpython-community-a-round-up-and-a-look-forward-to-2022/), don’t hesitate to let us know what you’d like to see from CircuitPython and the community throughout this year.

## Status Updates
@foamyguy (host)
* Finish up the bulk of the functionality for the Winamp project code. Working on this guide for it this week.
* Continuing PR testing and reviews. First time using a camera with CircuitPython this week to test out motion sensing capabilities of VC0706 camera.
* Streamed some displayio basics using the new split screen functionality on Thursday.
* Absorbing everything needed to run this meeting.
* Try to troubleshoot SSL error fetching Webb Telescope data from NASA URL.
@danh 26:22
* Fixed ESP32-S2 I2C problems by adding a combined I2C write/read common-hal operation.
* Fixed board default device update that was causing crashes on SAMD.
* Wrote a simple web server library. Works on ESP32-S2, and also works in CPython.
* Starting on a simple async web client library. It appears the `asks` library, an async version of requests, is a good starting place.
* Continuing to fix bugs for 7.x.
* FIgure out when to make the 7.2.0-alpha.2 release.
@jepler 29:06
* Last week:
* Floppies & PIO somehow took all week and still isn’t wrapped
* Rp2040 reading code with pio is working in arduino, but needs tidying
* One reason is that I spent a lot of time on a silly 3d printing project
* This week:
* Really wrapping RP2040 floppy reading & writing with PIO this week?
* Coming weeks:
* I’ve been asked to speak at an upcoming hybrid event hosted by the Dublin Linux Users Group, details to come.
@jerryn 30:16
* Responded to Forum question about using rfm9x library to communicate to arduino-LoRa library
* I had only used Radiohead in the past
* Arduino-LoRa works ok with default settings - you have to create the header manually. It just sends a string of bytes without a specific header.
* The Forum user wanted to use a non-default setting for spreading factor and it was not working. All of the CP and RadioHead examples use SF=7.
* Looks like the CP library is not correctly handling all spreading factors -especially 6, 11 and 12 need special handling. Trying to understand and will create a PR when I succeed.
* Tried RaspiOS 64 bit version with Blinka
* PulseIn needs minor change to install the libgpiod_pulsein64 lib. Filed issue. It’s an easy thing to fix, just not sure how to do it for a PR.
* With the file in place I was able to run the dht_simpletest with a dht22.
* Tried adding an ai-thinker-esp-01S (esp8266 with AT firmware) to a Maker-Pi-Pico board
* It actually works! There is a demo using the ESP_AT_CONTROL.
* I had not tried using it a a long time.
* THe Maker-Pi-Pico boards is really a nice tool.
@kattni 34:53
* Last week:
* Finished up my CP2022 post - https://blog.adafruit.com/2022/02/01/the-circuitpython-community-a-round-up-and-a-look-forward-to-2022/
* Published the Arcade QT guide
* Ran into issues with Arduino with the Arcade QT which led to a lot of troubleshooting
* Added content for the upcoming circuitpython.org/start
* Started the STEMMA QT rev update to the guide for the HT16K33 7-segment LED backpack
* This week:
* Update the ADXL345 board files on GitHub and in the guide
* Make sure the Arcade QT plays nice with a Metro (Arduino)
* Continue on the STEMMA QT rev update for the LED backpack
* Create some Learn groups in the Adafruit Learn System
* Get content up on circuitpython.org/trademarks
* QT updates for MCP4725 guide etc.
* Guide for the ADXL375
* DotStar status LED template
* asyncio template
* Possibly get my README blunder fixed up with Tekktrik’s script
@kmatch 38:51
Last week:
* Finalized PR to allow moving and resizing the REPL displayio Group
* Found and debugged a minor issue in display_text with word wrapping
* Learned about some challenges of re-using TFT displays by tearing down a conference room scheduler touch display <https://hackaday.io/project/183895-crestron-tsw-732-teardown>
* Found a multitouch touchscreen for experimentation (uses a Focal Tech FT5406 touch controller)
This week:
* Submit a new circuitpython_org library for a textBox widget with vertical scrolling
* Experiment with touch screen responses and data visualization. Maybe make a Focal Tech FT5x06 library (interrupts?)
@makermelissa 40:48
* Last week:
* Worked on porting LittleFS to JavaScript
* Mostly debugging errors at this point
* Now have an image being generated which has its files extractable
* This week:
* Finish fixing the final bugs in LittleFS
* Coming weeks:
* Also speaking at Dublin Linux Users Group with Jeff
@tammyamkesthings 41:32
* Last week:
* Contributed a PR to @mraleson’s “piku” CPY development tool to add macOS support to the tool.
* Creating a little helper script to probe the USB bus and set the Blinka environment variables based on which board is actually present on the system.
* Next week:
* Finish my helper script and share it
* Look for more places to contribute both to the core and the libraries
* Hopefully doing my first stream on Twitch (twitch.tv/tammymakesthings) focusing on microcontrollers, CircuitPython, and hardware hacking/making
@tannewt 42:54
* Last week
* Wrapped up #circuitpython2022
* working on getting GATT client going.
* Got service discovery working
* Got connecting working
* Got Characteristic buffer working
* Switched to a new DIY keyboard of my own. Running my custom circuitpython code. Trying not to get tooooo distracted perfecting it

* Get PR out for review
* Start on dynamic services going in NimBLE
@tekktrik [not present] 44:44
* Last week:
* Worked on script for fixing library repo READMEs
* Working on some more type annotation PRs
* Submitted PR for making touchpads iterable for CircuitPlayground, also allows to deinit them as needed which is a bonus
* Submitted PR for adding examples on pausing, resuming, and cycling LED animations using push buttons
* This week:
* Some additional follow through on other PRs that merged this past week
* More type annotations and anything else available in the Open Issues!
@v923z 45:37
* Last two weeks:
* Implemented a number of file IO features in ulab, fixed an incompatibility issue
* Coming weeks:
* Rolling out ulab version 5.0, trying to clean up documentation
## In The Weeds 48:52
@foamyguy 48:58
Anyone with SSL / HTTP request knowledge interested in helping to troubleshoot the “SSL handshake error” that we receive in CircuitPython if we attempt to fetch data from:
https://jwst.nasa.gov/content/webbLaunch/flightCurrentState2.0.json?unique=1643741752388
More info discussed in #help-with around here: https://discord.com/channels/327254708534116352/537365702651150357/938245775526355015
We’ve tried both ESP32-S2 based devices as well as ESP32SPI Airlift connections and had no luck with either.
@kattni 51:59 - (as suggested previously by @jepler) Consider updating the description on the “Long Term” milestone on the core to be something aligned with “While these issues are not a priority for Adafruit, we would absolutely love to have the community pick them up.” Thoughts?
@kattni 53:02 - As discussed in my CP2022 post, I want to see us do a call for input from the community more than once per year. I feel that this will help keep the community more involved with the evolution of CircuitPython versus one time per year. Sometime towards the end of April / beginning of May, and for CircuitPython Day (August) seems like a good place to start. The other two do not need to be as involved as the New Year call, and no one should feel obligated to respond to any of them. Thoughts?
