[Tinyos-help] Changing Sampling Rate For MDA300

Hi Jeremiah,

 

The XMesh apps all have a "appFeatures.h" file that has a constant defined
for the default update rate.

 

#define XSENSOR_SAMPLE_RATE  20000

 

This gets passed into the call to start the application timer:

          call Timer.start(TIMER_REPEAT, XSENSOR_SAMPLE_RATE);       

 

You can change it directly - it is in milliseconds.  The above example is a
20 second interval.

 

Note: MOTE-VIEW 1.2 (to be released soon) will allow you to change the
update rate dynamically from the GUI.

Subject: [Tinyos-help] Changing Sampling Rate For MDA300

 

Hi all,

I am using a MDA300 with a MICA2 and I am running the Xmesh program on it.

I am not a programmer, but I need to know how to edit the xmesh program to
change the sampling rate at which the MICA2 takes data from the MDA300.

If a programmer could tell me what source codes need to be edited and what
numbers need to be changed in the code, I would very much appreciate it.

Thanks

-Jeremiah Jazdzewski
