ONEWIRE(4)	       FreeBSD Kernel Interfaces Manual		    ONEWIRE(4)

NAME
     onewire --	1-Wire bus

SYNOPSIS
     onewire* at gpioow?
     onewire* at uow?
     onewire* at ioc?	    (sgi)
     onewire* at xheart?    (sgi)

     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.
