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 — that is, to measure temperature at multiple locations. This application 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.
