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.

Your device uses I 2 Cor often called 2-wire serial communication. Bence Kaulics 5, 10 23 This is the address you set as it datsaheet described in the datasheet and in Andy aka ‘s answer.

Null 4, 10 22 Can somebody explain to me further the interest of having those pins?

datashset Here’s what the data sheet says: As you can see there is a Slave Address field which is 7 bit long. I found out that it have 3 pins A0,A1,A2 which as specified in the datasheet are chip address input.

The next 3 bits of datasneet control byte are the device select bits A2, A1, A0. Sign up using Facebook. The control byte consists of a 4-bit control code; for the DS, this is set as binary for read and write operations.

Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line.
