Re: TI-H: TI <--?--> I2C


Your pictures are vague and confusing, but I think I understand the concept:
If the wires were red, white and black, then all the wires would be
connected to the other wires of the same color?  Like an electric circuit;
all pos wires connected, all neg wires connected, and all ground wires
connected?  Is this correct, or am I totally off?
