TI中文支持网大家好，我的项目现在需要用到FFT函数，现在遇到了一些问题：
CCS版本：6.2.0，芯片为F28335
为什么当我编译lib中自带的2837X_CFFT时，编译会出错呢？
报错内容如下：

感谢大家的帮助~
还有一个小问题：当我想在另一个工程中调用TI自带的FFT函数时，需要哪些步骤呢？有相关资料吗？谢谢了！
Green Deng：现在不清楚你的添加方法，一般来说是这样的：首先需要在CCS的工程文件中链接FFT库：在工程设置中C2000 Linker——file search path中添加该库和路径。并在主程序中包含下面头文件：#include "FPU.h"。

好的，非常感谢您的回复~
请问当我查看controlSUITE中的DSPlib 中的F28335中的FFT相关函数的时候，为什么文件中出现的是2837x相关的例程呢？
（路径如下：Chinese>库>DSP库>浮点>项目>打开示例项目文件）2837x_cfft/12/2/19 12:31:13 PM
