NAME

     shb -- bus for SuperH on-chip peripheral devices

SYNOPSIS

     shb* at mainbus?

DESCRIPTION

     The shb driver provides a bus to which drivers for integrated peripheral devices found in various SuperH microprocessors attach.

     adc       analog/digital converter.

     sci       serial communication interface.

     scif      serial communication interface with FIFO.

     wdog      watchdog timer.

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

	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>.
