您好，在默认安装路径安装C2000WARE后，请参考C:\ti\c2000\C2000Ware_4_01_00_00\libraries\math\FPUfastRTS\c28\docs目录下FASTRTS_SW_LIB_UG.pdf的4 Using the FPU Library，里面有详细的配置步骤。

您好，我按着这个配置了，但是FS$$DIV还是不能使用，您能帮助我一下吗？

您有参考哪个例程吗？

我参考的是您说的这个文件。然后配置了不对。这个浮点库配置需要添加.asm文件？如果您能帮我解决，我有偿付费。

我在您的另一个帖子中看到您似乎没有给fpu分配内存？

C:\ti\c2000\C2000Ware_4_01_00_00\libraries\math\FPUfastRTS\c28\examples\common\f2838x 下的 fastrts_examples_lnk.cmd 您参考一下。

您也可以把您的cmd文件发上来，我帮您看一下
