Description: F2812 标准FFT算法,128点,256点,512点,1024点FFT算法,具体做法为将库含数FFT.LIB加入的目标项目,加入对应的C含数和头文件,特别注意的FFT算法缓冲去一定要存放在0X8000H中的内部缓冲区中!!!切记,本人调试时就走了很多弯路啊-F2812 standard FFT algorithm, 128, 256, 512, 1024-point FFT algorithm, the specific approach to the library will join with several FFT.LIB goals, joined counterparts with the number of C header files, pay special attention to the FFT algorithm to buffer must 0X8000H stored in the internal buffer! ! ! remember, I debug away many detours ah

Description: Z再这里不能显示界面,所以我把界面的用法简单介绍下。(1)、此界面可以分为左右两部分,右边为数据的输入区域,左边为数据的显示和获得区域。本系统数据的输入和获得都是靠滚动条来完成的。在输入区域内,当拖动滚动条时,在滚动条的下方会显示相应的数据,以便用户了解准确的信息。如下图所示,指数为10,采用点数为1024,采样周期为0.050秒。图中数据显示范围有限制,但可以通过在程序中改变设定的值得到想要的数据范围。(2)、在数据输入完成后,拖动左边的滚动条可以得到分析的图像,其中上边显示的是实部的图像,下边显示的是虚部的图像。需要注意的是,当对图像不满意时,必须点击“图形刷新”按钮,重新输入数据。(3)得到满意的图像后,点击“数据获取”或“数据打开”按钮都可以获得相应的数据文件。

Description: DIT-FFT至简设计实现法
工程说明
案例补充说明
本案例无论是模块划分、计数器设计、还是乒乓操作的读写处理,都始终基于“至简设计”的原则,用简易的代码结构就能实现复杂的DIT-FFT蝶形运算,代码设计风格极其简洁,详细可参考附录代码。(DIT-FFT to Jane design and Implementation
Engineering description
This design is based on the discussion to simple design method to achieve the 2-FFT algorithm according to the base time selection (DIF-FFT) implementation process, support N from 8 to 1024.
Case Supplement
In this case, both the module division, the counter design, and the reading and writing of table tennis operations are always based on the "to Jane" design)
