Frequency Counter

Other Hardware Science and Measurement

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!

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