Frequency Counter

Hi,

I am going to use http://interface.khm.de/index.php/lab/interfaces-advanced/arduino-frequency-counter-library/. But I do not quite understand about the code.

FreqCounter::f_comp= 8; FreqCounter::start(100); FreqCounter::f_ready

What do these 3 lines means?

Thanks!

Google is your friend. Mine also. I could not find the double colon in my C++ book. Here is the answer:

I understand the double colon. lol I just do not understand why this code and the library can make arduino uno to measure frequency.
