Hello everyone,
I am trying to get values from TSR sensor on Tmote sky.
I followed the example in $TOSDIR/contrib/moteiv/apps/Oscilloscope/
Did the standard
myApp.nc:
components HamamarsuC;
Main.StdControl-> HamamatsuC;
myAppM.TSR -> HamamtsuC.TSR;
in myAppM.nc
uses {
interface ADC as TSR;
}
I have a time to collect N number of readings and put in the array
event result_t SensorPullTimer.fired(){
call TSR.getData();
return SUCCESS;
}
async event result_t TSR.dataReady(uint16_t data){
atomic {
if(pos == DATA_PAGE-1){
readings[pos] = data;
pos = 0;
call SensorPullTimer.stop();
post Write_Data();
}else{
readings[pos] = data;
pos++;
}
}
return SUCCESS;
}
All I get is FFFF values even when I cover sensor with my hand. I read
from: http://www.cs.berkeley.edu/~pal/mate-web/tutorials/lesson2.html
"Note that some Telos motes do not have their sensors populated. This
causes the totalsolar and photoactive sensors to return bogus values: they
are simple ADC captures. In contrast, the humidity and temperature
functions interact with digital sensors over a bus; if they are not
populated, the VM will enter an error state."
I am not sure what this means, but does any one know how to fix it?
Otherwise can some one point me into the direction of how to get TSR sensor
working.
Regards Tatiana.
