ONEWIRE(4) BSD Kernel Interfaces Manual ONEWIRE(4) NAME
onewire -- 1-Wire bus SYNOPSIS
onewire* at gpioow? option ONEWIREVERBOSE 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. SUPPORTED MASTERS
gpioow(4) 1-Wire bus bit-banging through GPIO pin SUPPORTED SLAVES

intro(4) HISTORY
The onewire driver first appeared in OpenBSD 4.0 and NetBSD 4.0. AUTHORS
The onewire driver was written by Alexander Yurchenko <grange@openbsd.org> and ported to NetBSD by Jeff Rizzo <riz@NetBSD.org>. BSD
