The 1-Wire protocol is a proprietary standard for serial data communication from Maxim Integrated. This protocol is a low-speed, half-duplex, bidirectional, low-power master-slave data communication standard used by several devices, including temperature sensors, real-time clocks, EEPROMs, identification (intellectual property protection) devices, timers, and iButtons. There can be only one master device on a 1-wire standard…
What is the 1-Wire protocol?
The 1-Wire protocol is a single-wire interface, half-duplex, bidirectional, low-speed and power, long-distance serial-data communication protocol. Although this protocol is classified as a 1-wire standard, at least two wires are required in the 1-wire standard bus — one for the data and/or power supply and another for the ground return. An additional wire might be…
