Hello:
Now I'm puzzled with the outputs of xlisten with both mica2 and mica2dot used.
I wrote TOSBase into one MPR400 mote and plugged it onto MIB510 as the
base station. Then I wrote XSensorMTS300 into one MPR400 mote with
MTS310 sensor plugged, XSensorMTS510 into one MPR500 with MTS510, and
XSensorMDA500 into another MTS510 with MDA500. When all these three
nodes were working, I run xlisten from Cygwin. It seemed things went
well. But I thought the outputs of xlisten seemed strange. I pasted
three pieces of them below.

adc chan 5: voltage=516 mv
adc chan 6: voltage=478 mv
adc chan 7: voltage=478 mv
These three nodes were placed close to each other, but there was
significant difference between the output data of light, mic, X-axis
Accel, Y-axis Accel of MTS310 and MTS510, and temperature of MTS310
and MDA500. So are there any explanations about this difference? And
are there any tools or programmes to fix the big difference of these
data? Thank you. ^-^
