21

STANDARD PROPERTIES

23   address
24   r_address
25       read-only, ascii
26       The  entire  64-bit  unique  ID. Given as upper case hexidecimal digits
27       (0-9A-F).
28       address starts with the family code
29       r address is the address in reverse order, which is often used in other
30       applications and labeling.
31
32   crc8
33       read-only, ascii
34       The  8-bit error correction portion. Uses cyclic redundancy check. Com‐
35       puted from the preceding 56 bits of the  unique  ID  number.  Given  as
36       upper case hexidecimal digits (0-9A-F).
37
38   family
39       read-only, ascii
40       The  8-bit  family  code. Unique to each type of device. Given as upper
41       case hexidecimal digits (0-9A-F).
42
43   id
44   r_id
45       read-only, ascii
46       The 48-bit middle portion of the unique ID number. Does not include the
47       family code or CRC. Given as upper case hexidecimal digits (0-9A-F).
48       r  id is the id in reverse order, which is often used in other applica‐
49       tions and labeling.
50
51   locator
52   r_locator
53       read-only, ascii
54       Uses an extension of the 1-wire design from  iButtonLink  company  that
55       associated  1-wire  physical  connections with a unique 1-wire code. If
56       the connection is behind a Link Locator the locator will show a  unique
57       8-byte number (16 character hexidecimal) starting with family code FE.
58       If  no  Link  Locator is between the device and the master, the locator
59       field will be all FF.
60       r locator is the locator in reverse order.
61
62   present (DEPRECATED)
63       read-only, yes-no
64       Is the device currently present on the 1-wire bus?
65
66   type
67       read-only, ascii
68       Part name assigned by Dallas Semi. E.g.  DS2401  Alternative  packaging
69       (iButton vs chip) will not be distiguished.

DESCRIPTION

75   1-Wire
76       1-wire is a wiring protocol and series of devices designed and manufac‐
77       tured by Dallas Semiconductor, Inc. The bus is  a  low-power  low-speed
78       low-connector scheme where the data line can also provide power.
79
80       Each  device  is  uniquely and unalterably numbered during manufacture.
81       There are a wide variety of devices, including memory, sensors  (humid‐
82       ity, temperature, voltage, contact, current), switches, timers and data
83       loggers. More complex devices (like thermocouple sensors) can be  built
84       with  these  basic  devices.  There  are  also 1-wire devices that have
85       encryption included.
86
87       The 1-wire scheme uses a single bus master and multiple slaves  on  the
88       same  wire.  The bus master initiates all communication. The slaves can
89       be individually discovered and addressed using their unique ID.
90
91       Bus masters come in a variety of configurations including serial,  par‐
92       allel, i2c, network or USB adapters.
93
94   OWFS design
95       OWFS  is  a  suite of programs that designed to make the 1-wire bus and
96       its devices easily accessible. The underlying principle is to create  a
97       virtual  filesystem,  with  the  unique ID being the directory, and the
98       individual properties of the device are  represented  as  simple  files
99       that can be read and written.
100
101       Details  of  the  individual slave or master design are hidden behind a
102       consistent interface. The goal is to provide an easy set of tools for a
103       software  designer  to create monitoring or control applications. There
104       are some performance enhancements in the implementation, including data
105       caching, parallel access to bus masters, and aggregation of device com‐
106       munication. Still the fundemental goal has been ease of use,  flexibil‐
107       ity and correctness rather than speed.
108
109   mRS001
110       The mRS001 (3) is a rotation sensor. It is packaged for industrial use,
111       requiring drilling the drive shaft or using special magnetic couplings.
112

ADDRESSING

114       All 1-wire devices are factory assigned a unique 64-bit  address.  This
115       address is of the form:
116
117       Family Code
118              8 bits
119
120       Address
121              48 bits
122
123       CRC    8 bits
124
125       Addressing under OWFS is in hexidecimal, of form:
126
127              01.123456789ABC
128
129       where 01 is an example 8-bit family code, and 12345678ABC is an example
130       48 bit address.
131
132       The dot is optional, and the CRC code can  included.  If  included,  it
133       must be correct.
