MEMORY
memory
read-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.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 aggre‐
gate of the pages. Each page is accessed sequentially.
SUB-TYPE
tag
read-only, ascii
Text description of the device. Up to 30 characters.
device_type
read-only, ascii
Device name. E.g: "EDS0071"
device_id
read-only, unsigned
Number corresponding to the hexidecimal type. E.g:
EDS0071 -> 0x0071 -> 113 in decimal
STANDARD PROPERTIESALARMS
None.
DESCRIPTION
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.
