Attached is xAPmcs1Wire.exe which is an xap interface to Dallas 1-wire
netw=
ork using DS9097U (serial) DS9490 (USB) or functional equivalent PC
adapter=
s to the 1-wire network. A full set of 1-wire/Ibutton devices typical of
a=
n HA environment are supported. This includes temperature, voltage,
humidi=
ty, lightning count, water flow, rainfall, wind direction, wind speed,
rela=
ys, switches, air pressure and probably some others that don't come to
mind=
at the moment. I'm making it available to enhance the library of BSC-comp=
liant applications.
The software uses the drivers developed by the Dallas Semiconductor. If
no=
t already installed on the PC then they can be downloaded from ftp://ftp.da=
lsemi.com/pub/auto_id/licensed/Install_1_Wire_Drivers_v400b3.exe
Earlier version of these drivers will also function, however some devices
a=
re not supported with the _v3 and erlier drivers. These drivers utilize
th=
e Microsoft Jave Virtual Machine. The JAVA VM will need to be enabled on
t=
he PC.
The file can be placed anywhere. It will create a \config subfolder and
ma=
y create a \data subfolder. When executed it will run in the tray and a
mo=
use click on the icon will provide selection options which include
"Setup" =
"IO Window" and "Exit". The other options have been
disabled as they only =
have meaning in the context of a system with other xap nodes that support
h=
ealth, redundancy management and centralized configuration management.
The "Setup" will show a Windows GUI that I quickly put together
to provide =
a stand-alone user interface. Normally this node is configured via a
centr=
alized configuration user interface. The xap schema to support the
configu=
ration discovery and modification are still enabled, but will cause no
harm=
.=20=20
The application-layer logic of this node was extracted from an existing
Hom=
eseer plugin so some of the setup context is not obvious. For typical use
=
the "Poll" button, the Metric/English units selection, and the
sample inter=
val will be the only setup items of interest.
The analog values are returned using the xapBSC.info schema. The discrete
=
values are reported with xapBSC.event and set with xapBSC.cmd. All
aspects=
of the BSC 1.3 schema have been implemented. Each 1-wire device has 6 xAP=
UID values reserved. This means a little over 40 devices can be supported=
per instance of the application. The body of the BSC xap message also has=
a Database=3DTrue key/value as these values are intended to be recorded by=
the xap datacollection node.
