I’m trying to add an external eeprom using i2c interface to a device that uses an Atmega64 controller. That’s fine and dandy. So then I go to the board and start tracing. I see that those go to a rocker switch with some simple circuitry that I haven’t had a good look at yet, but I assumed daatasheet was something i2c compatible.
But then what dawned on me was that this device has two such rockers so I expected to trace the other rocker back to the same two pins since i2c is a bus that can armega64 multiple slaves.
Well, now that confused me. Sadly, I’m not really sure what I’m asking.
Can someone shed some light on this? Nevermind, I found the answer. Its BOTH a bus and a simple input In this case, its being used as an input so I can’t also use it as a bus.
