在proteus下仿真的FFT试验！！！所得出的频谱波形在LCD12864 上显示-Under the simulation in Proteus FFT test! ! ! The resulting spectrum waveform shown in LCD12864

基于STC12C5A60S2的音频频谱显示,采用32.768MHz晶振，进行128点FFT变换，用32×64点阵将频谱显示出来。-, STC12C5A60S2-based audio spectrum with 32.768MHz crystal, 128-point FFT transform, and 3264 dot matrix spectrum is displayed.

C语言实现FFT算法，思维清晰，技巧行较强。-AES encryption algorithm (128) bit Verilog implementation, modular design, easy to understand.
