v2.0.0 Add support for ESP32S2 and update ESP-IDF to 4.4 (#4996)
This is very much still work in progress and much more will change before the final 2.0.0 Some APIs have changed. New libraries have been added. LittleFS included.

* @brief Convert complex FFT result to real array
|
||||
*
|
||||
* Convert FFT result of complex FFT for real input to real array.
|
||||
* This function have to be used if FFT used to process real data.
|
||||
* This function use tabels inside and can be used only it dsps_fft4r_init_fc32(...) was
|
||||
* called and FFT4 was initialized.
|
||||
* The implementation use ANSI C and could be compiled and run on any platform
|
||||
*
|
||||
* @param[inout] data: Input complex array and result of FFT2R/FFT4R.
|
||||
* input has size of 2*N, because contains real and imaginary part.
|
||||
* result will be stored to the same array.
|
||||
* Input1: input[0..N-1], Input2: input[N..2*N-1]
|
||||
* @param[in] N: Number of complex elements in input array
|
||||
*
|
||||
* @return
|
||||
* - ESP_OK on success
|
||||
* - One of the error codes from DSP library
