I can't seem to find an example of how to read the onboard chip product id code for a LM75 series sensor. Per the datasheet, if should be register 07h (0x07), i.e. 111. And returns 1 byte. But when I do the read of the 1 byte, it is always 255 or 0xFF. This does not seem correct.
I can read the temperature data just fine, and there are many examples of how to do this.
I would also like to find an example of how to turn the power mode on the sensor on and off as well.
