[Tinyos-help] Regarding Xlisten...!!!

Tue, 18 Apr 2006 18:38:03 -0700

Hi ,
   Thanks for those who have taken time to reply my last mail...sorry for troubling again but i  have one more querry.....I have been working on the following application......about which most of them should be familier...
          
Ø      To test sensor boards:
o        First make sure that you are in the directory:
/opt/tinyos-1.x/contrib./xbow/apps
o        Go to XSensorMTS300  (or MTS400 based on the sensor you are using)
o        Load sensor board on a mote that is uploaded with the right XSensor application.  use the command:
MIB510=COM1 make mica2 install.<nodeid>
o        Turn the mote on.
o        Load a mote on the MIB, turn it off, load it with TOSBase (from apps/TOSBase folder) using:
MIB510=COM1 make mica2 install.<nodeid>
o        Run from /usr/local/bin the following:
xlisten -r -p -c -b=mica2 -s=com1 –w
 
 
for which i got the following as one of the outputs...now i want to know  which bytes are for which measurement...where can i get the information about which  bytes are for Light...Temp...Batery...Mic...etc and  how are the conversions being done..?? 
                   Is there any Manual or any document where it specifies /clearly explains which bytes are being used for the measurements...??

mts310 id=01 vref= 1b0 thrm=020d light=038d mic=01e6
       accelX=01e6 accelY=0149 magX=0149 magY=00c8
MTS310 [sensor data converted to engineering units]:
   health:     node id=1 parent=0
   battery:  = 2898 mv
   temperature=26.10 degC
   light: = 2575 ADC mv         
   mic: = 486 ADC counts
   AccelX: = 720.000000 milliG, AccelY: = -2420.000000 milliG
   MagX: = 44.43 mgauss, MagY: =27.01 mgauss
 
            I would really appreciate if someone could spare sometime and reply back .....i am thankful to those who have replied to my earlier mail.
 
Thanks in Advance.
