ADAU1452 FFT Acquisition of amplitude and frequency

Hello,

I'd like to know how to obtain amplitude and frequency data from FFT library under ADAU1452 and SigmaStudio environment.

I refer to the following web site.

However, I do not know how to obtain amplitude and frequency data also.

If anyone knows, please let me know.

Thanks
