I’m migrating from Raspberry Pi Pico and have been looking for something like this!
Awesome!

Thank you for your thoughtful comment, Rob! Loose wires are like the “is it powered?” of the computer support world 🙂 Better to check than to spend hours debugging

1) One cause for the “no pull up found” error (which is what brought me here) can also be caused by a dumb mistake: having a loose wire! This happens to me all too often because I am using Stemma connectors which are a little finniky.

2) I think your example code is a little confusing, in that I think it could/should have started with the simplest case wherein you use the two available I2C controllers, such as

i2c = busio.I2C(board.SCL, board.SDA)
…
si2c = busio.I2C(board.A9, board.A6)

The methods you use after that are of course still valid and useful!
