hi all,
i have a project in which i want to interface a 8051 based micro controller to a triple axis accelerometer (ADXL345) using i2c protocal.
the problem i am having is this - the 8051 works off of 5 volts, and the accelerometer works off of 3.6 volts. i was thinking of somehow using zener diodes but i have no experiance in using them, have googled them but i just am not understanding them. a circuit diagram would be great if some one has one,
thanks for the help
