How to time between functions? Timer used.

[jwcheon]

Hi.

I want to know the time difference between functions by using a timer instead of a difference.
I've looked at app_timer.h, but it's hard to understand.

I do not need the Repeat function and I just want to be able to measure the time.
Please help me.

I just want to know when the function starts and ends.

For reference, I am using SDK14.1 and S140.

Hi,

I don't know what you mean by "I want to know the time difference between functions by using a timer instead of a difference". If you want to get a timestamp before and after the function stars, you can call app_timer_cnt_get. If you want to know the actual time, you need some reference to set the time, and keep track time, for instance as shown in this example.

Best regards,
Jørgen

Hi,
Thanks for the answer.

I succeeded in saving time as I gave you an answer.
However, I wonder what the unit of return value from app_timer_cnt_diff_compute () function is.

How many return values should be given as 1 second?
