Here’s what the data sheet says: Andy aka k 10 In this communication protocol the master selects a slave by sending its address to the bus, and the specific slave identifies itself by this address.
The one below is set to have address This is the address you set as it is described in the datasheet and in Andy aka ‘s answer. A little addition to Andy aka ‘s answer. The next 3 bits of the control byte are the device select bits A2, A1, A0.
