I use the frequency library on both Mega ADK ( modified library) and Nano board.
When i measure a precise 1.000.000 Hz signal I get 1.000.169 on the display.
I try to correct this with f_comp but it seems that i can only increase the displayed reading.
How can I decrease the reading to 1.000.000 ??
Thanks for a nice frequency library. Very usefull.
