Real Time FFT with ADC doubt

Hi all,

I am trying to understand the example code 2833x_RFFT_ADC_RT, provided in controlSUITE. When I call RFFT_f32_mag(&rfft), it returns me the buffer RFFTmagBuf[]. Can someone explain me how to convert the result in RFFTmagBuf[] from digital to analog?

Thanks,

Luiz Moreira
