So I'm using my Arduino as a slave device that sends data to an I2C master on request. Now this master also has 6 ports requesting data so I'd like to handle all this on the same board. Right now I've got a working program using the Wire library that works fine for a single port. Now I want to be able to use the same Arduino to act as up to 6 devices that could respond appropriately to requests for data.
From what I can tell the only hurdle is the multiple addresses that are necessary. The closest information I could find on this was this post which is asking the same thing but never seemed to be resolved.
The top answer seems to give a good idea but I'm not sure if I'd be wasting my time. Is there any other obvious way around this issue aside from using 6 different boards?
