I resent being called a troll.
I didn't call you a troll, I said 'I am beginning to think you are behaving like a troll', which is a statement of fact about my state of mind having read many of the replies to this discussion.
The reason has nothing to do with my background or yours, it has to do with seeing the same question being answered multiple different ways and answered multiple different ways and you still keep asking. The final trigger was you not answering when I asked in reply #48 where SDA is connected to Vdd. I hoped you would finally see that it wasn't, but instead you went on to say both that it was and it wasn't, which in my experience is classical troll type dodging the question to keep the answers flowing.
I get that you think VCC, VDD, and V+, 5V+ are the same, I have not commented on it because for the purposes of this discussion it does not matter. You can learn the difference later, when you know more generally.
