I am writing code for a 128. I want to use TWI using interrupt driven hardware functions. Does the standard lib for WinAVR support this? I looked at the documentation, and I could not tell if it was interrupt driven or not. I looked in the academy and elsewhere on this site and found a couple of different sources of TWI functions. But while the write-up may suggest it is interrupt driven, the headers sometimes disclaim that.
So, what is the best source for interrupt driven hardware TWI functions for the 128. I hope to avoid having to write my own (buggy) stuff.
