NAME

6       owfs.conf - owfs programs configuration file
7

SYNOPSIS

9       An OWFS configuration file is specified on the command line:
10
11       owfs -c config_file [other options]
12              The  file  name  is arbitrary, there is no default configuration
13              file used.
14

USAGE

16       A configuration file can be invoked for any of the OWFS programs ( owfs
17       [1m(1)  owhttpd (1) owserver (1) owftpd (1) ) or any of the language bind‐
18       ings ( owperl (1) owcapi (1) owtcl (1) owphp owpython ) to set  command
19       line parameters.
20

SYNTAX

22       Similar to Unix shell script or perl syntax

DESCRIPTION

55   1-Wire
56       1-wire is a wiring protocol and series of devices designed and manufac‐
57       tured by Dallas Semiconductor, Inc. The bus is  a  low-power  low-speed
58       low-connector scheme where the data line can also provide power.
59
60       Each  device  is  uniquely and unalterably numbered during manufacture.
61       There are a wide variety of devices, including memory, sensors  (humid‐
62       ity, temperature, voltage, contact, current), switches, timers and data
63       loggers. More complex devices (like thermocouple sensors) can be  built
64       with  these  basic  devices.  There  are  also 1-wire devices that have
65       encryption included.
66
67       The 1-wire scheme uses a single bus master and multiple slaves  on  the
68       same  wire.  The bus master initiates all communication. The slaves can
69       be individually discovered and addressed using their unique ID.
70
71       Bus masters come in a variety of configurations including serial,  par‐
72       allel, i2c, network or USB adapters.
73
74   OWFS design
75       OWFS  is  a  suite of programs that designed to make the 1-wire bus and
76       its devices easily accessible. The underlying principle is to create  a
77       virtual  filesystem,  with  the  unique ID being the directory, and the
78       individual properties of the device are  represented  as  simple  files
79       that can be read and written.
80
81       Details  of  the  individual slave or master design are hidden behind a
82       consistent interface. The goal is to provide an easy set of tools for a
83       software  designer  to create monitoring or control applications. There
84       are some performance enhancements in the implementation, including data
85       caching, parallel access to bus masters, and aggregation of device com‐
86       munication. Still the fundemental goal has been ease of use,  flexibil‐
87       ity and correctness rather than speed.
88
89   Configuration
90       owfs.conf  (5)  allows  a  uniform set of command line parameters to be
91       set.
92
93       Not all OWFS programs use the same command line options, but  the  non-
94       relevant ones will be ignored.
95
96       Command  line and configuration options can mixed. They will be invoked
97       in the order presented. Left to right for the command line. Top to bot‐
98       tom for the configuration file.
99
100       Configuration  files  can  call  other configuration files. There is an
101       arbitrary depth of 5 levels to prevent infinite loops.  More  than  one
102       configuration file can be specified.
