How to access the Arduino i2c on Ubuntu?

Hello,

How can I access the arduino i2c on the LattePanda 3 Delta? I have installed Ubuntu 22.04 on the Delta, and it shows me 16 i2c devices (/dev/i2c-0 - 15) but it does not seem to be any of these devices. Do I need to install something to get the Arduino i2c to show up?

Also (maybe related), when I use the command i2cdetect, I get the warning: can't use SMBus Quick Write - will skip some addresses. Not sure what this is.
