Dallas 1 wire protocol
1-Wire is a device communications bus system designed by Dallas Semiconductor that provides low-speed (16.3 kbit/s ) data, signaling, and power over a single conductor. 1-Wire is similar in concept to I²C, but with lower data rates and longer range. It is typically used to communicate with small … See more 1-Wire devices are available in different packages: integrated circuits, a TO-92-style transistor, and a portable form called an iButton or Dallas key which is a small stainless-steel package that resembles a watch battery. … See more When developing and/or troubleshooting the 1-Wire bus, examination of hardware signals can be very important. Logic analyzers and bus analyzers are tools that collect, analyze, decode, and store signals to simplify viewing the high-speed waveforms.
