快速傅立叶算法，C语言编程，进行频谱分析 -FFT C,FFT spectrum

该程序可以使示波器产生方波信号，运用c语言进行编程。-The program allows the oscilloscope produces a square wave signal, using c language programming.

利用单片机C语言编程，设计一个程序，产生三角波和矩形波，并能在示波器上轮流显示，显示时间间隔可调.-Using microcontroller C language programming, design a program to produce triangular and rectangular waves, and can turn on the oscilloscope display, the display time interval is adjustable.
