any FFT acceleration (hardcore FFT in APU or FFT accelerator)

[mzy2240]

Maix has two ways to accelerate the FFT process, using the APU or the individual FFT accelerator. Is it possible to use any of these sources with Maixduino?

In fact, you can use these functions by calling functions in sdk, only need #include "fft.h" or other interfaces provided in sdk. We have recently used Class to encapsulate these peripheral libraries. It will be simple and easy to understand in the Arduino style API. If you have any good ideas or what features you need, please let us know.
