DESCRIPTION
1-Wire bus was originally developed by Dallas Semiconductor for connecting integrated circuits. It is commonly used for connecting devices such as electronic keys, EEPROMs, temperature sensors, real-time clocks, security chips, etc.
The onewire driver provides a uniform
programming interface layer between 1-Wire master controllers and various
1-Wire slave devices. Each 1-Wire master controller attaches a
onewire framework; several slave devices can then be
attached to the onewire bus.
The driver supports plugging and unplugging slave devices on the fly.
