NAME
     onewire -- 1-Wire bus

SYNOPSIS
     onewire* at gpioow?

     option ONEWIREVERBOSE

DESCRIPTION
     1-Wire bus was originally developed by Dallas Semiconductor for connect-
     ing integrated circuits.  It is commonly used for connecting devices such
     as electronic keys, EEPROMs, temperature sensors, real-time clocks, secu-
     rity 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
        owid(4)     ID family type device
        owtemp(4)   temperature family type device

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>.
