Welcome to the most recent Python on Microcontrollers e-newsletter! The neighborhood continues to hum proper alongside this week. We’re studying extra in regards to the RP2350, Raspberry Pi’s second microcontroller, the great and an rising bump within the highway. A brand new model of CircuitPython is out, and extra individuals than ever are giving it a attempt. And the outcomes of the Python Software program Basis’s newest survey are out with some attention-grabbing figures. All this and far more on this jam-packed concern. – Anne Barela, Editor

What’s new in Raspberry Pi Pico 2
Within the newest concern of The MagPi Journal, Raspberry Pi CTO James Adams offers a better have a look at what’s new in Raspberry Pi Pico 2 – Raspberry Pi Information.
5 methods the Raspberry Pi Pico 2 can take your initiatives to the following stage – YouTube.
The maker neighborhood continues to characterize a {hardware} concern with at the moment launched RP2350 A2 stepping chips. The difficulty was initially characterised as an issue that may happen if a pin is about as an enter with the interior pull-down resistor enabled. If the pin is introduced externally to three.3v, after which the three.3v is eliminated, the pin output turns into latched at barely over 2 volts, as an alternative of being at floor. Raspberry Pi issued erratum RP2350-E9, which discusses this concern and describes a workaround for studying the pin worth.
However later studies by Adafruit, Harmful Prototypes, Pimoroni, and others have proven that enabling the interior pull-down resistor doesn’t appear to be required to set off the 2V latch-up. Statement additionally exhibits that externally grounding the pin with ample present clears the latched state. Raspberry Pi and the neighborhood are actively investigating this evolving concern, so please consult with the most recent developments if the difficulty impacts your designs. – Raspberry Pi Pico Suggestions, concern #401 and related subjects within the Raspberry Pi Discussion board.

Is it time to replace the Open {Hardware} Definition for AI or make a parallel one for AI?
It is perhaps time to replace the Open {Hardware} Definition, it’s over 10 years outdated. So much has modified within the final 10+ years for open-source {hardware} and open-source software program, and a few issues haven’t! There was/is an Open Supply {Hardware} (OSHW) Definition 1.1 draft, however has not been up to date on the wiki since December 10, 2018. Phil Torrone has some options – Adafruit Weblog.
“Whereas there are some things I’d replace on the Open {Hardware} Definition 1.0 my focus is on including one thing to handle AI/ChatGPT/people working with LLMs, and so forth. I’m going to suggest the identical factor that I’ve tried to have the Open Supply Initiative contemplate for his or her OSI + AI license / definition.
The objective is sharing which actual instruments had been used and in what methods to permit others to duplicate (and iterate) with AI/LLMs, and so forth. It’s slightly completely different than commenting code, or publishing code beneath an open-source license, however the intent may be the identical. My addition to the definition is restricted to this “freedom”: “Research how the system works and examine its parts.” The OSI + AI definition at the moment leaves out the inspection of prompts and knowledge entry transparency.”

What’s the CircuitPython staff as much as this week?
What’s the staff as much as this week? Let’s verify in:
Dan
Final week I launched CircuitPython 9.1.3, which fixes some board and chip-specific issues.
I’m engaged on merging Micropython v1.23 into CircuitPython, and have accomplished the preliminary merge. Subsequent I’ll evaluation the merge, clear up some free ends, and begin testing.
I’ve been investigating and additional characterizing a {hardware} drawback with the RP2350 that causes enter pins to latch up at about 2V. Raspberry Pi revealed an erratum describing the circumstances during which this will occur, however testing by me and others appears to point it’s extra pervasive. See the information merchandise earlier on this e-newsletter for extra particulars.
Melissa
This previous week I’ve been engaged on fixing bugs within the CircuitPython Code Editor in addition to updating the WebSerial ESPTool to work with the ESP32-C6. Nevertheless, after updating the WebSerial ESPTool, it’s now not working with the S3 boards for some of us. I might be trying into that this subsequent week. I even have been engaged on a Residence Assistant mission to have the ability to entry Adafruit IO. I’m going for one thing that works in an analogous method to MQTT.
Jeff
I used to be away for about 4 weeks. The majority of that point I used to be on a few picture safaris in Kenya and Tanzania. In the event you’re try some photographs from my journey. To whet your urge for food, right here’s an elephant crossing a mud highway simply toes from our car:
I’m again now and dealing on the record of points we’ve focused to repair earlier than the discharge of 9.2.0 secure. First up was enhancing error reporting for analogbufio on Espressif-family microcontrollers when an unsupported pattern fee is requested.
Tim
This week I moved a number of extra libraries to Ruff after getting their repo atmosphere setup regionally to evaluation and check another PRs. I’ve begun engaged on including serial plotter performance to the CircuitPython web-ide. Lastly I’m refactoring the vectorio intersection capabilities that I began a number of weeks in the past to be module capabilities as an alternative of sophistication capabilities.
Scott
I used to be largely out within the final week to spend time with visiting household. The remainder of the time I’ve been fixing bugs with a purpose to get 9.2.0 prepared for launch. A lot of the fixes are in 9.1.x releases as properly. The newest repair of mine was dashing up the flash and PSRAM connection on the Qualia to scale back the show glitching. The speeds now match those utilized in 9.0.x. They had been slowed in 9.1.x as a result of threat of instability when the temperature modified.
