Hello,

In regard with the addressing, the LM75B slave address on the I2C-bus is partially defined by the logic applied to the device address pins A2, A1 and A0. Each of them is typically connected either to GND for logic 0, or to VCC for logic 1.

So, based on your A0-A2 pins configuration, the address will be composed as follow:

The complete protocol for writing and reading the registers are mentioned on the chapter 7.10 from the datasheet.

Please let me know if you have any further question.

Regards,

David
