Function Documentation

adi_fft_init()

int adi_fft_init	(	struct adi_fft_init_params *	param,
		struct adi_fft_processing *	fft_proc,
		struct adi_fft_measurements *	fft_meas
	)

Initialize the FFT structure.

Parameters

param[in]	- FFT init parameters
fft_proc[in,out]	- FFT processing parameters
fft_meas[in,out]	- FFT measurements parameters

Returns

0 in case of success, negative error code otherwise

adi_fft_perform()

int adi_fft_perform	(	struct adi_fft_processing *	fft_proc,
		struct adi_fft_measurements *	fft_meas
	)

Perform the FFT.

Parameters

fft_proc[in,out]	- FFT processing parameters
fft_meas[in,out]	- FFT measurements parameters

Returns

0 in case of success, negative error code otherwise

adi_fft_update_params()

int adi_fft_update_params	(	struct adi_fft_init_params *	param,
		struct adi_fft_processing *	fft_proc
	)

Update the FFT parameters.

Parameters

param[in]	- FFT init parameters
fft_proc[in,out]	- FFT entry parameters

Returns

none
