ehm.. e come disattivo quelle di arduino? devo modificare qualcosa nella Wire.h?
comunque grazie, sto trovando un po' di risposte:
"Of course as you add more and more devices to the lines the bus capacitance will increase and that means you'll have to start decreasing your resistance (t = RC) if you want to maintain your signal integrity."
anche se " so it's always good practice to look at the signals on an oscilloscope. " e io non saprei come fare
