NAME

owfs.conf - owfs programs configuration file

SYNOPSIS

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

USAGE

A configuration file can be invoked for any of the OWFS programs ( owfs (1) owhttpd (1) owserver (1) owftpd (1) ) or any of the language bindings ( owperl (1) owcapi (1) owtcl (1) owphp owpython ) to set command line parameters.

SYNTAX

Similar to Unix shell script or perl syntax Comments # Any # marks the start of a comment # blank lines are ignored Options option # some options (like 'foreground') take no values option = value # other options need a value option value # '=' can be omitted if whitespace separates Option # Case is ignored (for options, not values) opt # non-ambiguous abbreviation allowed -opt --opt # hyphens ignored owserver server: opt = value # only owserver effected by this line ! server: opt = value # owserver NOT effected by this line owhttpd http: opt = value # only owhttpd effected by this line ! http: opt = value # owhttpd NOT effected by this line owftpd ftp: opt = value # only owftpd effected by this line ! ftp: opt = value # owftpd NOT effected by this line owfs owfs: opt = value # only owfs effected by this line ! owfs: opt = value # owfs NOT effected by this line Limits # maximum line length of 250 characters # no limit on number of lines

DESCRIPTION

1-Wire 1-wire is a wiring protocol and series of devices designed and manufactured by Dallas Semiconductor, Inc. The bus is a low-power low-speed low-connector scheme where the data line can also provide power. Each device is uniquely and unalterably numbered during manufacture. There are a wide variety of devices, including memory, sensors (humidity, temperature, voltage, contact, current), switches, timers and data loggers. More complex devices (like thermocouple sen‐ sors) can be built with these basic devices. There are also 1-wire devices that have encryption included. The 1-wire scheme uses a single bus master and multiple slaves on the same wire. The bus master initiates all communication. The slaves can be individually discovered and addressed using their unique ID. Bus masters come in a variety of configurations including serial, parallel, i2c, network or USB adapters. OWFS design OWFS is a suite of programs that designed to make the 1-wire bus and its devices easily accessible. The underlying principle is to create a virtual filesystem, with the unique ID being the directory, and the individual properties of the device are represented as simple files that can be read and written. Details of the individual slave or master design are hidden behind a consistent interface. The goal is to provide an easy set of tools for a software designer to create monitoring or control applications. There are some performance enhancements in the implementation, including data caching, parallel access to bus masters, and aggregation of device communi‐ cation. Still the fundemental goal has been ease of use, flexibility and correctness rather than speed. Configuration owfs.conf (5) allows a uniform set of command line parameters to be set. Not all OWFS programs use the same command line options, but the non-relevant ones will be ignored. Command line and configuration options can mixed. They will be invoked in the order pre‐ sented. Left to right for the command line. Top to bottom for the configuration file. Configuration files can call other configuration files. There is an arbitrary depth of 5 levels to prevent infinite loops. More than one configuration file can be specified.
