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.
The onewire driver first appeared in
OpenBSD 4.0.
The onewire driver was written by
Alexander Yurchenko
