[Tinyos-help] Tr : calculate Time in seconds

[Rannouna Rania]

Hi,

I used :
clock_t  initial_time;
clock_t  final_time;
float CPU_time;
In my code ;
initial_time= clock();
tate(mip,P,Q,res);// I need to know the time required by this function
final_time=clock();
CPU_time=final_time - initial_time;
if I display on the PC this value (CPU_time)  I found 15,000 (I think clock ticks but I want in seconds).
I hope that is more clear now.
Thank you very much.
Best Regards,
Rania

If you are using TimerMilli or LocalTimeMilli each tick is a binary millisec.  There are 1024 per second.

Not sure from your description what you are trying to do.  Can you be clearer?

Hi all,

Thank you all for your Kind response and your help.
In fact I am new in tinyos, so that sometimes I ask questions that seem maybe evident.
Now my problem is that I want to calculate the time needed by my application in seconds.
I succed to calculate it in clock ticks.
Have you any idea how can I do this? I guess  I should use the SimpleTime component but I can't understand  how to use it (I am going to use the telosb).
Thank you very much in advance.
Best Regards,
Rania
