Hi,

I want to find frequency, average value and peak value of AC waveform from A/D channel.

Are there FFT libray or example code for S9KEAZN16?

Hi, Hong,

This is the link of the Automotive Math and Motor Control Library Set for KEAx devices.

Real Time Control Embedded Software Motor Control and Power Conversion Libraries|NXP 

As you can see that it does not support FFT.

As Mark said that the CMSIS library supports FFT.

Hope it can help you

Hi

Try the ARM CMSIS DSP libray, including FFT examples.
