[hpsdr] I2C vs 1-wire

[Alex]

We were doing this in case of someone wanting to connect two ATLAS boards? Wouldn't we run into timing and signal loss issues interconnecting the boards? Wouldn't it be better just to run a whole other independant chassis plugged into the USB?
I'm just wondering the conditions that would lead to this. I'm also wondering how often we think it might happen.

The concern was having to address more than 8 serial EEPROMS in a system.
