Measuring time

Hi all !

I am currently testing RIOT in native to create a network with nodes communicating using UDP and RPL. I would like to measure time of specific functions but I didn’t find a way to do it, is there anything implemented to measure time ?

Then, I plan to create this network with msp430 nodes if it’s possible with the new release. So, for msp430, is there a way to measure execution time ?

Thanks for your help,

Hey Caroline,

you can use xtimer_now() [1] to get the current system time before the function call and again after the function call. Then you can calculate the difference. xtimer_now() returns an uint32_t and the unit is microseconds.

Best, Cenk
