Hi Dr. Harrison,
Thank you for your helpful reply. Actually I realize that the interface is the most convenient way to see turbidostat connection.
Also, I am wondering if I can use other bus to communicate with integrate chi bio with pH sensor. I understand that the beagle bone have channel 0, 1 and 2 for communication but chi bio multiplexer only use 2nd bus. Is there any specific reason that you dont touch channel 1?
