cortex-m0新塘工程模板，不需要新建工程，直接用(cortex-m0 Xintang project templates, no new construction, the direct use)

Plot the log-magnitude of the Fourier transform of the signal over the interval [0, π], using a 1024-point FFT. The signal should be windowed with a Hamming window of two different durations: 25 ms and 10 ms with the window placed at the signal’s center in each case. Show the log-magnitude plot for each duration.
