ONEWIRE(4) BSD Kernel Interfaces Manual ONEWIRE(4)NAME
onewire -- 1-Wire bus
onewire* at gpioow?
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
SEE ALSO intro(4)HISTORY
The onewire driver first appeared in OpenBSD 4.0 and NetBSD 4.0.
The onewire driver was written by Alexander Yurchenko <firstname.lastname@example.org> and ported to NetBSD by Jeff Rizzo <riz@NetBSD.org>.

FIREWIRE(4) BSD Kernel Interfaces Manual FIREWIRE(4)NAME
firewire -- IEEE1394 High-performance Serial Bus
To compile this driver into the kernel, place the following line in your kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
FreeBSD provides machine-independent bus support and raw drivers for firewire interfaces.
The firewire driver consists of two layers: the controller and the bus layer. The controller attaches to a physical bus (like pci(4)). The
firewire bus attaches to the controller. Additional drivers can be attached to the bus.
Up to 63 devices, including the host itself, can be attached to a firewire bus. The root node is dynamically assigned with a PHY device
function. Also, the other firewire bus specific parameters, e.g., node ID, cycle master, isochronous resource manager and bus manager, are
dynamically assigned, after bus reset is initiated. On the firewire bus, every device is identified by an EUI 64 address.

The firewire driver first appeared in FreeBSD 5.0.
The firewire driver was written by Katsushi Kobayashi and Hidetoshi Shimokawa for the FreeBSD project.

I'm making script for Dallas temperature sensors (DS1820).
When a sensor is connected, it shows up as a directory in /sys/bus/w1/devices
in format 10-xxxxxxx. Inside the directory is a file called w1_slave which holds the temperature in format t=xxxxx.
