An identifying and authorizing application using 1-wire® technology

This paper presents a hardware and software application using the 1-wire technology. The application has several components: 1-wire network of iButton® type devices, addressable switches, serial EEPROM memories, the software package developed for Windows operating system. The application achieves several goals: 1-wire network interrogation, data processing, implementation of several control functions of identification and authorizing type. The solutions given have advantage of the hardware simplicity, which is specific to the 1-wire technology, and high efficiency in building complex network architectures. The practical usefulness of the application presented is to be found in the industrial field, in intelligent building, in alarm and anti-burglary systems, in sensor networks, etc.
