MEMORY¶
memory¶
read-write, binary
96 bytes of memory. Not all is writable. Access to

better accomplished through the data fields, which expose all the chip
features.
pages/page.0 ... pages/page.2 pages/page.ALL¶
read-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/memory¶
read-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.0-4 EDS008X/pages/page.ALL¶
read-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.

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 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
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 priciple 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 fundemental
goal has been ease of use, flexibility and correctness rather than speed.
EDS00XX Overview¶
The EDS00XX sensors are a family of devices from
Embedded Data Systems.
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.
Relay and LED¶
All the
EDS00XX sensors have an LED and optional relay. Both can be
controlled either directly, or when the sensors reaches an alarm state.
ADDRESSING¶
All 1-wire devices are factory assigned a unique 64-bit address. This address is
of the form:
- Family Code
- 8 bits
- Address
- 48 bits
- CRC
- 8 bits
Addressing under OWFS is in hexidecimal, 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.
