CircuitPython support

[theboyknowsclass]

Any chance this will work in CircuitPython?

There are some Raspberry Pi Pico functions still lacking from micropython :(

It works on CircuitPython, but only on their 9.x pre-releases. They have some bugs that prevent Microdot from working on the 8.x and older versions that I reported to them, and my understanding is that these are only fixed on the main branch, towards the 9.x release.

I am still having a problem using under circuitpython:

code.py output:

I'm sorry, you are correct. I have missed that they do not have a usocket class. Unfortunately there isn't much I can do, they need to fix their asyncio module to support creating a server. See adafruit/Adafruit_CircuitPython_asyncio#35.

The reason I was considering CircuitPython is that the Pico support for SD cards is gone from Micropython. It's just SPI. Might be easier to get that working than the other way around.

I haven't used it for a while but I believe SDCard support is available for all ports? Just needs to be mip-installed (or copied) to your device:

https://github.com/micropython/micropython-lib/blob/master/micropython/drivers/storage/sdcard/sdcard.py

Let me know if that's not working for you...

You are right, it got moved from core to the separate -lib repo, but only for some ports. It is still in core on ESP-32. Thanks for the heads up. I will be building a web configured combat robot timer that the 4 boxes talk to each other via web services API. At least that's the plan, because UART required too many dedicated ports. I will put this little thing through its paces, and find ways to make it better. It will run on ESP32-WROOM or Pi Pico. Not 100% sure yet. The SD card is just a way to get network setup in there without needing to have USB connections and uncommon PC software.
