Null 4, 10 22 Bence Kaulics ratasheet, 10 23 What are the address input pins used for in ds? I just bought a ds temperature sensor and started reading its datasheet. Post as a guest Name. Can somebody explain to me further the interest of having those pins? In this communication protocol the master selects a slave by sending its address to the datqsheet, and the specific slave identifies itself by this address. Basically, if you have several DS devices, you can set the hardware address for each and exclusively read up to 8 devices.

The control byte consists of a 4-bit control code; for the DS, this is set as binary for read and write operations. ChiPlusPlus 1 1 By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

They are used by the master device to select which of eight devices are to be accessed. Here’s what the data sheet says: This is the address you set as it is described in the datasheet and in Andy aka ‘s answer. Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line.
