Hello guys,
I am using FreqCounter Library for reading a frequency of an audio signal,,
anybody used it before?
can u please give me a description about how it works and how it can read the freq? does it used FFT for multiple signal or what?
I read about it here but I really can't find it so useful: http://interface.khm.de/index.php/lab/experiments/arduino-frequency-counter-library/
best regards,
Seriously?
From the link you included:
The Frequency input is fixed to digital pin 5. This pin is mapped to the alternate port function T1 which is the input 16 Bit Hardware Counter1. To obtain a higher resolution than 16 Bit, the counter overflows are counted also and are calculated with the counter value to the final long integer result.
I have simulate this frequency counter library using ISIS Proteus and display it to text LCD. this Demo video i uploaded at Simple frequency counter using Arduino - YouTube.
Thank you.
