MCU-PLUS-SDK-AM273X: How to add a Window function or log magnitude function with HWA2.0 in the hwa_real_fft sample project?

Lin Li

Tool/software:

Hello Support team,

I have imported, built and run the sample hwa_real_fft project code. FFT and IFFT work well. How can I add a window or log magnitude function to the fft function in the hwa_real_fft project?

Thank you very much for your help and support.

Best regards,

Lin

Hi Lin,

You can use the CCS --> Tools --> Graph --> FFT Magnitude for log magnitude function. For the window function, you have to write your own code to implement it. The

hwa_real_fft sample project only do the FFT/IFFT for the input data.

Best regards,

Ming
