Hi Roman, some answers

You should't have to.

I did accidentially circulated some ATmega168 with the correct firmware but wrong fuse settings. They were usable like that (encoded PPM) but the LED's didn't flash propperly, you would need an ISP to fix one of those (or just use it like it is).

Apart from using a logic analyser or scope, I don't think so.

> As I know for ATmega168 it was the frequency of the LED. Is it the same for ATmega328?

I think they behave exactly the same (assuming they are set up right :). There are a few versions kicking round though, I haven't tried all of them.

Thanks.
