Hi Matthias, Looking at the core/devices/atmega328p directory (for the Uno) I see three 'device.*' files and the atmega328p.frt file, which all have the notation "generated automatically, do not edit". In each of those I note references to the TW* declarations desired for my Uno. If I shouldn't be editing these files, I'm unclear what actions I'm to take to get them properly modified. My understanding is that the only place I should be modifying anything is in the master project asm file. If this is the case, then it appears to be significant as to specifically where an addition (a WANT option, for instance) is to be inserted.

The/most WANT-Options I consider legacy stuff ;) Can you give me an example of what you mean here, perhaps pertaining to I2C functionality? > > > I insert that line, compile and flash the Uno, but when I look for > > the declarations of TWBR, etc., I don't find them.
