Addressing
All 1-wire devices are factory assigned a unique 64-bit address. This address is of the form:
FamilyCode
8 bits
Address
48 bits
CRC 8 bits
Addressing under OWFS is in hexadecimal, of form:
01.123456789ABC
where 01 is an example 8-bit family code, and 12345678ABC is an example 48 bit address.
The dot is optional, and the CRC code can included. If included, it must be correct.
Alarm
Show or clear the out-of-range flags. When set, the device will respond to a conditional search. Clearing
the flags is performed with the EDS00XX/alarm/clear command, not just having the measured value return to
the center range.
EDS00XX/alarm/clearwrite-only,yes-no
Write "1" to clear ALL the alarm flags.

Description
1-Wire1-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 sensors) can be built with these basic devices. There
are also 1-wire devices that have encryption included.
The 1-wire scheme uses a single busmaster 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.
OWFSdesignOWFS 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 communication. Still the fundamental goal has been ease of use,
flexibility and correctness rather than speed.
EDS00XXOverview
The EDS00XX sensors are a family of devices from EmbeddedDataSystems. Although provisional support for
several types is included, only early EDS0071 has been tested with OWFS.
The sensors all share the same 7E family code. They have the same first memory page layout with a text
tag property that describes them, and a sub-type field giving the particular sensor. The data properties
shown in a directory listing will be specific to the sensor sub-type.EDS0071
The EDS0071(3) is a micro-processor based 1-wire slave made by EDS (Embedded Data Systams). Is uses a
high accuracy and extended range RTD sensor to accurately measure temperatures.
Memory
The EDS00XX sensors are read and controlled by accessing parts of their on-chip memory. Although the raw
memory contents are exposed in the memory and pages fields, all the available functionality is best
accessed by the other fields. In fact, directly changing memory will confuse OWFS.RelayandLED
All the EDS00XX sensors have an LED and optional relay. Both can be controlled either directly, or when
the sensors reaches an alarm state.

Humidity
EDS006X/humidityread-only,floating-point
Relative humidity in the 0-100 range (percent). Read every 0.2 seconds.
EDS006X/dew_pointread-only,floating-point
Dew point computed from EDS006X/temperature and EDS006X/humidity computered every 0.2 seconds. Data is a
calculated temperature and is reported in the specified temperature scale. Default Celsius.
EDS006X/heat_indexread-only,floating-point
Heat index computed from EDS006X/temperature and EDS006X/humidity computered every 0.2 seconds. Data is a
calculated temperature and is reported in the specified temperature scale. Default Celsius.
EDS006X/humidexread-only,floating-point
Humidex (popular in Canada) computed from EDS006X/temperature and EDS006X/humidity computed every 0.2
seconds. Data is a percent and reported in the 0-100 range.

Memory
memoryread-write,binary
96 bytes of memory. Not all is writable. Access to EDS00XX functions is better accomplished through the
data fields, which expose all the chip features.
pages/page.0...pages/page.2pages/page.ALLread-write,binary
Memory is split into 3 pages of 32 bytes each. Only page 2 is writable. ALL is an aggregate of the
pages. Each page is accessed sequentially.
EDS008X/memoryread-write,binary
160 bytes of memory. Not all is writable. Access to EDS008X functions is better accomplished through the
data fields, which expose all the chip features. The EDS008X has more memory than the other chips, so a
separate entry in the sudbirectory makes it available.
EDS008X/pages/page.0-4EDS008X/pages/page.ALLread-write,binary
Memory is split into 5 pages of 32 bytes each. Only page 5 is writable. The EDS008X has more memory than
the other chips, so a separate entry in the sudbirectory makes the extra pages available. ALL is an
aggregate of the pages. Each page is accessed sequentially.
