How ro calculate time interval ?

[Hiloshi]

Dear Sirs,

I want to measure how much time consumption between two event.
I hope it can accurate to micro second at least.

Could it possible to do it ?

Normally, I use oscilloscope to measure time interval by GPIOs, however it is not possible in embedded system.

Appreciate for any suggestions~

Perhaps: QElapsedTimer::nsecsElapsed() which returns elapsed time in nanosecoonds
