Need switch for Xbee bidirectional i/o? (note: not a wireless question)
Not a wireless question, assume xbees work.
I'm considering Xbee bidirectional i/o line passing. I would have a situation like this one:
(Note: I've been told that on an Xbee, some pins can be input and some can be output. Also, for simplicity I didn't show the Xbees, just the relevant pins. And also the two Xbees are on different boards.)
I'm not sure this would work though. Say if both sides were 3.3V, then one side got pulled to GND, would the change propagate to both sides, or would it be just 1.5V or something?
I guess I would need some kind of switch that would send it to one wire if the value was high, and send it to another wire if the value was low. But the switch should be automatic, it shouldn't need to be manually adjusted.
