DSPLIB 32-bit fixed-point complex FFT example for Simulator Documentation

Introduction

This example demonstrates how to use the 32-bit complex FFT function.
To visualize the result, you may set a breakpoint after the sprintf and check the string variable output through Watch Window in AVR Studio 5. Through this page, you can access the DSP Library documentation.
