[Tinyos-help] Adjusting the Data Sampling Rate of MicaZ

[alvindarjit singh]

Hi guys,

I am using MIB520, MDA300 and two micaZs to form a simple mote that sends
data to my pc.
I am facing a problem whereby my mote sends data after every 2 seconds.
my intention is to program micaZ so that it would send readings from MDA300
every 1 minute when the input to ADC2 is >2.0 volts, and
every 2 minutes when the input to ADC2 is <2.0 volts.

I am using Programmer's Notepad 2 to modify the file XMDA300M.nc. And i
noticed that
the supporting file sensorboardApp.h has the following lines in the end of
its program
 "...

#ifdef APP_RATE
uint32_t XSENSOR_SAMPLE_RATE = APP_RATE;
#else
#ifdef USE_LOW_POWER
uint32_t XSENSOR_SAMPLE_RATE = 184320;
#else
uint32_t XSENSOR_SAMPLE_RATE = 1843;
#endif
#endif

uint32_t   timer_rate;

 ..."

which might explain why my mote sends back data every 2 seconds.

how can i modify codings of both or either one files to achieve my desired
sampling
pattern ?

your help is very much appreciated.
Thank you.

Best Regards,
Alvin
