Hi,

for using Arduino Due you need at least Arduino IDE 1.5.8. The guys have changed some parts including wire. So you can use this tool if you replace this line from the code:

      TWBR = (F_CPU/(speed[s]*1000) - 16)/2;

with this part

#if ARDUINO >= 158
      Wire.setClock(speed[s]*1000);
#else
      TWBR = (F_CPU/(speed[s]*1000) - 16)/2;
#endif

I tried this with the Arduino nightly build of 1.6.0 and it works fine on my Due.

Best regards
Nils
