Hi,
I want to convert the 2D-FFT result (32bit) of IWR1642 demo(SDK 2.0.0.4) to 16bit and output it by SPI.
(Request from our customer.)
In the function MmwDemo_interFrameProcessing () in the file dss_data_path.c, DSP_fft32x32 () outputs 32bit 2D-FFT result. Please tell me how to convert this 32bit data to 16bit.
Since I want to leave the IWR1642 demo as it is for the subsequent processing, I want to perform 2D-FFT in 32bit instead of 16bit.
Best Regards,
Hiroyuki Taguchi
