ATmega1284P - arduino uno pro- freq count

Hi

did anyone try to read frequencies on arduino uno pro? http://www.hobbytronics.co.uk/arduino-uno-pro

I am using FreqCounter.h
I have had included ATmega1284P ( guide on site above)

but I get no input readings

code

#include <FreqCounter.h>

#include <Wire.h>
#include "RTClib.h"
#include <SPI.h>
#include <SD.h>
#include <PinChangeInt.h>
float frq,FdBm, BdBm;

void setup() {
  Serial.begin(57600);
  Serial.println("Frequency Counter");

}

void loop() {
  //PCintPort::attachInterrupt(5, measure, RISING); 
  measure();
}

void measure(){
  //PCintPort::detachInterrupt(5);
  
  delay(10);
  FreqCounter::f_comp = 1;
  FreqCounter::start(10);

  if (FreqCounter::f_ready == 0)
    frq = FreqCounter::f_freq; // read result

  frq = frq - (frq * 0.00034);
  frq = frq * 100 * 80;
  
  Serial.println(frq);


  FdBm = analogRead(A2) * 5 / 1023;
  BdBm = analogRead(A3) * 5 / 1023;
}

Does anyone know what to change in FreqCounter.cpp?

Thank you
