Hello to everybody,

 

I am working in the Xsensor application and I am trying to acquire data as fast 
as it is possible. In this sense, in the file called TestMTS400M there is a 
command which define the sampling rate:

 

#define TIMER_PERIOD 1000          // timer period in msec
#define GPS_MAX_WAIT 20          // max wait time for gps packet = 
GPS_MAX_WAIT*TIMER_PERIOD
#define MSG_LEN  29                     // excludes TOS header, but includes 
xbow header

 

If it is defined like this, it means that the program will wait 1000 ms for the 
next reading is it ok?. How can I vary the command to acquired faster data, 
because using the xlisten application after varying the command " #define 
TIMER_PERIOD 10" seems that it is not acquiring data at 100Hz.

Another question that I have is that following an existing post the sampling 
time is defined in binary seconds which means that for acquiring data to 1 Hz 
the command should be 1024 and not 1000. Is this an error of the tutorials or I 
am misunderstanding the problem? 

 

Many thanks for your help!!!!

 

Rafael
