Regain Location Information by Leveraging the 1-Wire® Chain Function—A Simple Signaling and Protocol Method Determines Device Physical Location

Abstract: As technology has evolved towards lower-cost serial bus systems using protocol-based addressing, the knowledge of the physical location of a component has been lost. This can be a problem if the serial bus is used for instrumentation or control purposes, e.g., to measure temperature at multiple locations. This app note details how to regain location information with lower-cost serial bus systems, such as 1-Wire, through the new built-in chain function of the DS28EA00.
