Video is available [on YouTube](https://youtu.be/mewDFnjzxIk).
Join here for the chat all week: http://adafru.it/discord.
The CircuitPython Weekly Meeting normally is held at 2pm US ET/11am PT on Mondays. Check the #circuitpython channel on Discord for notices of change in time and links to past meetings. Meeting times are also available in [iCal format](https://raw.githubusercontent.com/adafruit/adafruit-circuitpython-weekly-meeting/master/meeting.ical) for use with standard calendar applications and can also be viewed [in your browser](https://open-web-calendar.hosted.quelltext.eu/calendar.html?url=https%3A%2F%2Fraw.githubusercontent.com%2Fadafruit%2Fadafruit-circuitpython-weekly-meeting%2Fmain%2Fmeeting.ical&title=CircuitPython%20Meeting%20Schedule&tab=agenda&tabs=month&tabs=agenda).

## 2:12 Community News
### Raspberry Pi Release `piolib` for Raspberry Pi 5 RP1 Programming
PIOlib/libPIO is a user-space API to the `rp1-pio` driver, which gives access to the PIO hardware of the RP1 on a Raspberry Pi 5. It will be an important method of running time critical GPIO interface code, such as using smart LED strips (like NeoPixels). It takes the form of a clone of the PICO SDK PIO API, where most of the methods are implemented as RPC calls to RP1 - [GitHub](https://github.com/raspberrypi/utils/tree/master/piolib) and [NeoPixel Example](https://github.com/raspberrypi/utils/blob/master/piolib/examples/ws2812.c).
@jepler has the code working and is integrating it into libraries for community use.
### 3:46 An Updated CircuitPython Plug-in for VSCode is Available
Will S Merkens has come to the rescue of many in the community who have asked for a working VSCode extension for CircuitPython development. Will forked an older, broken version and has applied fixes - [GitHub](https://github.com/wmerkens/vscode-circuitpython).
### Newsletter Details
The Python on Microcontrollers Weekly Newsletter is a CircuitPython-community-run newsletter emailed every Monday. The complete archives are [here](https://www.adafruitdaily.com/category/circuitpython/). It highlights the latest Python on hardware related news from around the web including CircuitPython, Python and MicroPython developments.

## 15:20 Hug reports
@danh (hosting)
* @jepler for numerous CircuitPython fixes over the past week.
16:00 @CGrover (text only)
* @foamyguy for the informative and imagination-sparking Karel the Robot stream.
* Group hug
16:14 @foamyguy
* Jose for submitting more sensor displayio examples
* Jeff for looking into and fixing a rounding issue with locations inside of adafruit_turtle
16:37 @jepler
* Group hug
* Thanks to Tim for fixing a bug in Turtle that I introduced
16:55 @tannewt
* @jimmo for the gut check about moving CircuitPython to Zephyr.
17:15 @todbot (text-only)
* Mark (@gamblor21) & Tim (@foamyguy) for helping get the MTM Workshop Computer synth going with CircuitPython
* Cooper (@relic-se) & Jeff (@jepler) & Mark (@gamblor21) for the recent audiofilters work. The echo and filter effects are a lot of fun! Can’t wait to try distortion
## 17:44 Status Updates
@danh (hosting)
* CircuitMatter: I started working on native mbedtls cryptography access, but didn’t have enough information. Instead I went back to the Python version of ecdsa, removed all the Python 2 compatibility stuff, and trimmed it to include only what is required for Matter, which removes a lot of code. I kept testing as I trimmed, so I know it still works. I have a few more things to trim or rewrite and will then try it in CircuitPython.
* Fixed missing alarm module on many 4MB Espressif boards. This is worth a 9.2.2 release soon.
20:20 @CGrover (text only)
* Wrapped up the software side of the new weather architecture. The final step is to install the Source device into a hardened enclosure out in the dusty workshop. Playground Note: https://adafruit-playground.com/u/CGrover/pages/remix-cedar-grove-weather-architecture-v2-0
* Will be reawakening the thermal imager project with a new sensor. Anticipating improved performance since a bunch of changes were made to CircuitPython displayio/vectorio since the first implementation. Excited to incorporate some tricks learned with PaletteSlice and PaletteFilter to improve pseudo-color images. I’m betting that ulab will play a prominent role.
* A FeatherWing PCB design to emulate the “all-in-one” PyPortal functionality for ESP32-S3 Feathers and the 3.5-inch cap-touch TFT Wing is in the works. Although it won’t be compatible with the PortalBase library, it will have the essential audio output, temperature sensor, light sensor, and funky 3 and 4-pin JST-PH Stemma connectors. Q: Why? A: ‘Cause I have quite a few existing PyPortal projects that could use the upgrade to ESP32-S3.
21:34 @foamyguy
* Continuing to work on library issues. This week included some fixes in adafruit_turtle and type annotations / ruff for display_button as well a few in other various libraries
* Implemented Karel the robot with displayio / TileGrid. It’s a utility to help teach the fundamentals of programming that was created by a stanford graduate student in the 70s.
23:20 @jepler
* Pio neopixel now working on pi5 in circuitpython. Compatible with LED animation library, etc. temporary home is https://github.com/jepler/adafruit-blinka-neopixel-pi5 – installation:
* install latest firmware on pi5
* install latest kernel on pi5 & reboot
* pip install git+https://github.com/jepler/adafruit-blinka-neopixel-pi5 adafruit-circuitpython-led-animation adafruit-circuitpython-pixelbuf adafruit-blinka
* sudo chmod 666 /dev/rpi0
* wget https://raw.githubusercontent.com/jepler/adafruit-blinka-neopixel-pi5/refs/heads/main/examples/led_animation.py
* python led_animation.py
* Working on an implementation of StateMachine which will initially target the features needed for neopixel & build from there
* Another target is support for RGB Matrix Bonnet on PI5
* Will not be a fully compatible StateMachine replacement, will just hit key functionality needed
* Based on my current understanding it’s not possible to do a concurrent read & write operation (like StateMachine.write_readinto) though maybe it can be done by doing a write ioctl in one thread and a read ioctl in another.
* Other items:
* Fixed a problem with moving fractional pixels in adafruit turtle
* Changed how memory could be allocated for ssl objects on espressif microcontrollers with psram
* Fixed board.DISPLAY on floppsy
* Fixed a glitch in MP3Decoder when switching streams
* Removed some unneeded code in some setter functions in the core
* Set up the 2025 calendar for public meetings
* Submitted a fix for the module filename in a community library. I think this is the last thing before we can drop a workaround in the bundle builder.
25:55 @tannewt
* Got an nRF52840 build of CP + Zephyr linking but haven’t tried it on the DK. That’s my next step.
* nRF boards now live at the top level. Builds happen from the top level too.
* Zephyr cmake calls into async python script that builds circuitpython (replacing our makefiles.) Async python handles parallelism and skipping already done work.
* Monday and Tuesday will be off and on as we get ready for our travel. Wednesday is a travel day. The rest of the week is NYC visit and hacking when we have time.
* Next week we’ll be in Michigan and off and on. Not sure what our plans are. Out completely 12/23 - 1/2.
* I think we should do #CircuitPython2025 in January. Any objections or suggestions?
* Other stuff:
* Replaced nvme drive that failed as part of my BTRFS RAID1 root partition. Went surprisingly smoothly.
* Playing around with meshtastic on lilygo tdeck.
## 28:45 In The Weeds
* Any feedback or suggestions for #CircuitPython2025?
## 32:00 Wrap-Up
Next meeting is Monday December 16 at the usual time. The meeting following that will be Monday January 6, 2025!
