Hi,
First, thank you for releasing this very exciting board.
This issue may be better posted at another place; if this is the case, please just let me know and I will move it.
I see that the processor supports taking FFTs in an effective way:
https://github.com/sparkfun/OpenLog_Artemis_Geophone_Logger/blob/master/Firmware/OpenLog_Artemis_Geophone_Logger/Geophone.ino
However, there is still quite a bit of low level "obfuscation" for n00bs like me to use it.
Would it be possible to get a few wrappers that provide a dead simple interface to take a FFT on some data, for example something like:
constexpr size_t fft_size = 512; class FFT_Analyzer{ public: float16_t timeseries_in_real[fft_size]; float16_t timeseries_in_complex[fft_size]; float16_t fft_out_real[fft_size]; float16_t fft_out_complex[fft_size]; void perform_fft(void); };
or something like this, which would simply perform the fft analysis from the timeseries_in into the fft_out, with documentation of what the admissible buffer sizes are, and other possible tricks and tips?
Many thanks in advance!
