ONEWIRE(4) FreeBSD 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
owtemp(4) temperature family type device
