Atmega1280 as slave device

Dear all,
somebody knows how to make Atmega1280 to work as Slave device when it gets commands with Repeated Start from Master.
With conventional library "Wire" it doesn't work and I didn't find something useful in www.

With conventional library "Wire" it doesn't work

With convention library, "Wire", I expect it to (oh, no I can't tell you). Instead, it does (oh, not I can't tell you that, either).

Ah, well, I thought you wanted help. Moving on...

A bit more detail perhaps? What device? What is your code? What are you expecting it to do, and what is it in fact doing?

I believe there is a library that handles repeated start, I can't recall its name or where you get it.
