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. ChiPlusPlus 1 1 This is the address you set as it is described in the datasheet and in Andy aka ‘s answer. Post as a guest Name.

They are used by the master device to select which of eight devices are to be accessed.
What are the address input pins used for in ds? Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line. Null 4, 10 22 I just bought a ds temperature sensor and started reading its datasheet.
Can somebody explain to rs1621 further the interest of having those pins? Your device uses I 2 Cor often called 2-wire serial communication.

Andy aka k 10 Here is a picture of I 2 C ‘s message frame. The one below is set to have address Home Questions Tags Users Unanswered. Bence Kaulics 5, 10 23 Sign up or log in Sign up using Google.
In this communication protocol datasheett master selects a slave by sending its address to the bus, and the specific slave identifies itself by this address. Email Required, but never shown. These bits are in effect the 3 least significant bits of the slave address.

Basically, if you have several DS devices, you can set the hardware address for each and exclusively read up to 8 devices. A little addition datasheey Andy aka ‘s answer. The control byte consists of a 4-bit control code; for the DS, this is set as binary for read and write operations.
