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
