Using 'i2c' to refer to a legal implementation is no more illegal than a restaurant putting 'Coke' on their menu. What does Philips want? They want royalties from implementations of i2c, and they do not want the term diluted by using it to refer to other similar protocols. So I don't think that just changing to 'iic' would pacify them in either of these cases. If it's truly i2c I don't think they care what you call your variables, (just so the chip manufacturer pays up) and if it's not, find a completely different name. Mark C.
