Re: I2C and simulator
I suggest you give up on the simulator and use the real hardware. Ultimately, you'll end up chasing real problems as opposed to simulator bugs. It's much more satisfying to solve real-world problems. ;-)
You'll need to use the addresses as pointed out by FvM. Commentary: Probably the worst disservice we do to students is make them think that simulators are the same as the real world. Basically, they double your work load because you not only need to understand the simulator (and all its deficiencies or bugs) but then also need to test the design with real hardware. (I do use simulators for things like power supply analysis but, based on what I've seen on this board, most LCD and device simulators seem to have their share of bugs.)
