I would like to read the frequency value that comes from an external circuit (using arduino like a frequencymeter).
At the beginning I used the Arduino328 and the FreqCounter library worked very well. Now, I am using the arduino Yun with the atmega32u4 and I need to adapt the code for this MCU.
I read several thread about freqcounter for arduino Leonardo, Micro, ecc (all with atmega32u4) but other guys have the same problem without a solution!
Someone has idea how to solve this trouble?!?
Finally, using the arduino yun, I want to share these data by wifi (about this step I don't have a problem)
