Hello!
I've gotten the device located at https://www.adafruit.com/product/4471 to work via Python on both Windows and through Linux, on a Pi as it happens, but not using its Stemma QT / Qwiic connection. I'm wondering if anyone has gotten the MCP2221 to talk to a SeeSaw 816 or the 817 one through that connection. Also on which platform was this accomplished. Now I've also gotten the SeeSaws to work via Python but also via Linux and the Pi, so getting it to work there, that is through the Windows build of Python, would be a major accomplishment.

Can you clarify what is "not working"?
Just connected an MCP2221A to a ATtiny816 seesaw and it shows up in an I2C scan:

Re: Newer MCP2221A question
Nothing. This is all at the theoretical status. I am asking if anyone has tried it before and seen what has happened. And can also provide examples. Yours is the first.adafruit_support_carter wrote: ↑Wed May 31, 2023 1:59 pm Can you clarify what is "not working"?
