This is a family 01 device that is recognized by both mcsTemperature and xapmcs1Wire. I belive the implementation it to treat it such that if present the DeviceStatus is ON and OFF is not present.

DS2890 Support
Support for DS2890 (Variable Resistor) is added to V1.4.0 using the BSC schema. This includes only the 3-pin package as no pump control activation is supported.
A typical info or event message is
xap-header
{
v=12
hop=1
uid=FF000506
class=xAPBSC.info
source=mcs.OneWire.MCS5:COM1.C600000005EAA92C.Index
}
output.state
{
state=OFF
displaytext=<table><td><img alt='Index' src='/images/sensors/index.gif' height='16' width='16'><img alt=' ' src='/images/sensors/blank3.gif'></td><td valign='middle' align='left'>77</td></table>
level=77/255
}
A tpical command message to change the setting is a level value in the range 0 to 255 such as the 77 in the below message. The commanded state has no affect on the DS2890 device.
xap-header
{
v=12
hop=1
uid=FF000E00
class=xapbsc.cmd
source=mcs.Xap.MCS6
target=mcs.OneWire.MCS5
}
output.state
{
id=6
state=on
level=77
}

Help!
I grabed the 1.5.0 version and started it up yesterday only to have mcs1-wire stop on me an hour or so later. Now I cannot get the exe to load. I have tried reverting to previous version with no avail. I had installed another piece of software yesterday and thought maybe it had interfered but un-installing it doesn't help. All my other xAP applications run ok. I am lost as to why xp pro will not run the exe.
Any ideas or suggestions?

Any quick ideas why a DS2760 would identify on the network but not return any data ? I have a new moisture meter using this device and I can't get it to output data. I figure my soldering skills suck but if it shows up with an ID it should return data - right ?
ThanksBruce

Bruce,
Have you tried using the onewireviewer application to see if you are getting anything? If you can get the ID you should see something being returned even if is a zero. If you are getting zeros then you should check for solder bridges, those 2760s can be a bear to solder

The DS2760 is a 1-Wire High Precision Li+ Battery Monitor and I use it in my Moisture Meter kit. Here are the specs for DS2760 chip.

Yes it is a hobby-boards project, here is the URL to the page.

There is a schematic there which hopefully makes more sense to you than me but it looks like it is measuring a voltage to determine the amount of moisture at the sensor.
I'll try the onewireviewer to see it that returns data - I just thought it was another battery monitor and I already test a circuit with a DS2438 and figured this would work also.
Thanks,Bruce

Michael,
It measures the moisture by measuring the current draw of a 555 oscillator circuit. The frequency will increase with the increase in moisture and with the increase in frequency the circuit will draw more current. The DS2760 measures the current by measuring the voltage drop across a resistor.
