The 'family-code' embedded in the lasered ROM number of each 1-Wire device signifies a specific device type. Since each device type has different features and commands, it is imperative the 1-Wire master knows how to translate this 'family-code' into the correct commands. This document presents a method to dynamically configure the 1-Wire master to correctly communicate with a previously unknown 1-Wire device type by providing the 1-Wire master with an XML configuration file. This document was originally created to support the IEEE 1451.4 A Smart Transducer Interface for Sensors and Actuators—Mixed-Mode Communication Protocols and Transducer Electronic Data Sheet (TEDS) Formats standards committee.
