## **MicroPython at FOSDEM**

**![MicroPython at FOSDEM][image1]**

MicroPython will once again be joining forces with Espruino at [FOSDFEM](https://fosdem.org/2025/) this year, 1-2 February in Brussels. Their table will be in building AW and they'd like you to show off your projects using MicroPython. There will also be two [talks by Jon Nordby](https://fosdem.org/2025/schedule/event/fosdem-2025-4524-milliwatt-sized-machine-learning-on-microcontrollers-with-emlearn/) \- [X](https://x.com/micropython/status/1881661639209930838?t=xLLPAgM27LMWvteRfXVgAw&s=03).

## **Project of the Week: Upcycling an Air Quality Sensor**

**![Air Quality Monitor Pairs a Salvaged PM2.5 Sensor with an Adafruit KB2040][image2]**

Using a PM2.5 sensor pulled from a broken "smart" air purifier, Daniel James created a simple two-component CircuitPython-powered air quality monitor using a Raspberry Pi RP2040-based Adafruit KB2040 microcontroller board \- [hackster.io](https://www.hackster.io/news/daniel-james-air-quality-monitor-pairs-a-salvaged-pm2-5-sensor-with-an-adafruit-kb2040-183c08bcd13b), [website](https://thzinc.com/2025/01/22/simple-pm2-5-particulate-monitor.html), and [GitHub](https://github.com/thzinc/simple-particulate-monitor).

## 15:41 Hug reports

@jepler (hosting)

* PaulCutler for pumping out episodes of The CircuitPython Show & for having the stamina to record 4 episodes this week (including an episode where I’m one of the guests)\!

16:51 @CGrover (text only)

* @PaulCutler for the invitation to join The CircuitPython Show podcast to talk about my weather station obsession. Very therapeutic.  
* @DJDevon3 for two recent Playground Notes ([NTP Clock](https://adafruit-playground.com/u/DJDevon3/pages/circuit-python-matrix-portal-s3-ntp-clock) and [Sunton display](https://adafruit-playground.com/u/DJDevon3/pages/7-sunton-esp32s3-8048s070-circuit-python)). I always pick up a useful code snippet or two from Devon’s projects.  
* SamBlenny for the [Greenhouse Temperature Logger](https://adafruit-playground.com/u/SamBlenny/pages/greenhouse-temperature-logger) Playground Note with an excellent example of how to incorporate ESP32-S3 sleep mode. Also with bonus analytic .csv files and spreadsheets\!

17:39 @danh

## 20:21 Status Updates

@jepler (hosting)

* A change of mine from last year finally landed in micropython, making the parsing of numbers slightly more compatible with CPython, including making an invalid number like \`07\` not be accepted in a .py file. It also saved a little bit of flash space due to re-organizing some existing code, so it was a win/win.  
* More updates to Pico-PIO-USB to improve resource allocation & allow use of the 3rd PIO block on the RP2350 and swapped D+/D- lines  
* Made another release of the Python hub75 library for Pi5 computers that improves framerate slightly, removes a workaround, and adds a /dev/fb0 (framebuffer) mirroring example program  
* Made another release of the Python neopixel library for Pi5 computers that makes it work better with multiple strips on different pins

22:58 @danh

* Debugging NINA-FW update. Something is failing in SSL socket setup.  
* Debugging CPy with ESP-IDF 5.3.2 on ESP32-C3. If BLE is enabled, board boot-loops. 5.3.1 is fine with BLE turned on.  
* Fixed RP2 DMA issue. Code code be cleaned up more, but fine for now.  
* 9.2.4 release soon due to fixes of significant bugs.

@DJDevon3 (text only)

* Started playing with the Sunton ESP32-S3 8048S070 “yellow display”. Getting a 7” 800x480 display working with Circuit Python and displayio is pretty awesome. From a GUI design perspective, having 4x the screen real estate is drool worthy. Wrote a [playground note](https://adafruit-playground.com/u/DJDevon3/pages/7-sunton-esp32s3-8048s070-circuit-python) for it. There is something not quite right with the colors being displayed. Green shows up as a lime green and orange looks yellow. Attempting to take a screenshot resulted in an image with obvious RGB565 color swapping issues, perhaps because there’s no palette involved with a dotclock display. Needs investigation. 

@eightycc (text only)

* Testing a “ramlog” module that writes messages to a circular buffer in RAM. Useful for debugging where logging messages to a file or I/O device interferes with timing. Includes a Python binding that facilitates message unloading and a custom handler for logging from adafruit\_logging.  
* Using “ramlog” I’ve been looking into a couple of RP2 port issues involving the CYW43. With a large (1MB) log buffer in PSRAM I’m able to capture detailed network traffic while not interfering with timing. Logging a message typically takes \<30 microseconds on an RP2350.  
* Fixed an interesting issue with RP2 port MP3 streaming over WiFi that manifested itself as an interrupt loop.


26:17 @foamyguy

* Working on Sparkle Motion learn guide  
* Fix for code.circuitpython.org Web-Ide for USB REPL based workflow  
* Handling guide feedback  
  * Prepared GameControls library for release in the community bundle so that it can be used by old TileMap game guide which doesn’t work under current versions of circuitpython. 

26:49 @tannewt

* Continuing work on Zephyr on CircuitPython.  
  * Did more work for RA8 and RA6 dev kits. We use a custom branch now that merges in pending support for them.  
  * Working on WiFi support on nRF7002. Took all deep dive to realize I wasn’t waiting long enough for results. 🤦I’m excited to get back into it. This is the first board with 5GHz band support that I know. ESP32-C5 has it as well. (But I don’t have one.)  
  * Thach merged in Zephyr support to TinyUSB so I’ll need to switch to it.  
  * Once I have networking going I may continue onto Ethernet and LTE or switch to getting the build system integrated into CI so I can PR what I have.

## In The Weeds

29:26 @foamyguy \- updating code.circuitpython.org with the changes from beta branch?

31:31 @Snakey Maker Cat (text only)  
Clarification: status of the CircuitPython stm32 ports 

I have been working on the Daisy Seed port, and it's been challenging, but moving ahead \-- the first PR is opened: [https://github.com/adafruit/circuitpython/pull/9974](https://github.com/adafruit/circuitpython/pull/9974)   
I am in the process of adding uf2 bootloader and SDRAM support as well, and was planning to ask for help with the audio (and other) modules that don't seem to exist on the stm32 chips. 

With the new Zephyr integration, is this work becoming obsolete? Can any of it be used with Zephyr?   
And is there a time estimate until Zephyr "takes over" ?
