How to include FPU functions? (rfft32)

Other Parts Discussed in Thread: CONTROLSUITE

Hi all,

I am trying to include RFFT_f32 in my program but I keep getting "unresolved external" errors when I compile. I have set the include options to point to "${FPU_LIB_VER_ROOT}/include" and "${FPU_LIB_VER_ROOT}/source" which I thought would do the trick but not so. I'm sure this is a simple question but I can't seem to figure it out.

Thanks,

Tom

You probably need to go into the build properties of your project, C2000 Linker -> File Search Path, and add the name of the library, C28x_FPU_Lib.lib, in the top section and its path i.e. C:\TI\controlSUITE\libs\dsp\FPU\v120\lib (assuming thats where it resides on your machine) to the bottom section
