has anyone gotten `ImportError: no

I dont see Matrix portal M4 on the supported boards. But i do see the Matrix portal S3. https://docs.circuitpython.org/en/latest/shared-bindings/analogbufio/index.html

Is there a work around or am i SOL?

Looks like that module has only been implemented on the ESP32 and RP2040 chips. Not the M4

Thank you for your response, @median folio . Going to code my own solution. Maybe I can use the source code from RP2040 or ESP32

oh if you do, please consider contributing it back to the core! A lot of people (including me) love the M4-based boards. The source for the RP2040 one is here: https://github.com/adafruit/circuitpython/tree/main/ports/raspberrypi/common-hal/analogbufio

Where is the source for the matrix portal m4?

Or is it the source for a family of M4 boards?

Probably here im assuming https://github.com/adafruit/circuitpython/tree/main/ports/atmel-samd/common-hal

[median folio]

yep

I am attempting to use the ESP32-S2 to do the Nunchuck cat toy project in Adafruit. However, it has never been discoverable in my file explorer. I have attempted to reload the boot folder from the web esp site but keep getting a SlipRead Error Timed out waiting for packet header message. This board has never been discoverable as a drive. I am also attempting to use a M4 express to operate the Joy featherwing that one seemed to work as described it was discovered and did all the library uploads as directed but the copy.y code listed in the tutorial when I copy and past it into the copy.y file get import board no module named "board" I am completely new to circuit python and the feather boards and am having issues getting them to work thanks for any assistance

think you might this in the main chat
