Hello, I was hoping to use some sort of soft I2C library to achieve I2C interface. The thing is the application has limited space, so I can't use a 32U4 or a 328P. I've been looking around and the 16U2 seems suitable except the fact that it doesn't have I2C embedded. Do the soft I2C libraries work …

Go get yourself a Digispark:

It employs a Attint85 and plugs into a USB cable.
