TMS320F28P550SJ: TMS320F28P550SJ使用SysConfig1.23可以同时配置RFFT功能和USB功能吗？能否给出例程。

请问：TMS320F28P550SJ可以同时使用RFFT功能和USB功能吗？

我使用usb_ex1_dev_serial例程，往里面加入F28P55x_rfft_fpu32例程中的RFFT计算功能，会出现编译不过。反过来使用F28P55x_rfft_fpu32例程，往里面迁移usb_ex1_dev_serial的功能，也会出现编译不过。如下所示：

所以，TMS320F28P550SJ可以同时使用RFFT功能和USB功能吗？

您好，

       一个是软件功能，一个是接口功能，是不冲突的。      

请问怎样同时调通这两项功能？
