Hello all,as mentioned here http://arduino.cc/en/Main/ArduinoBoardDueArduino Due's I/O Voltage was changed from 5V to 3.3V.Does this also mean that we have to change the voltage of the I2C Devices like DS1307, DS1820?ThanksBen
I thought that I2C was open-collector / open-drain - so it shouldn't matter what the voltage level is.
