FPU Library, sprc530

Clark Molster

Hi Champs,

Sprc530 describes how to use the FPU for use with 28335 devices. Trouble is, the compiler (CCS 3.3) can't find 'rts2800_fpu32.lib' because it doesn't exist on the host machine. I cannot find this file on the website either. We tried sprc664 and sprc624. sprc624 looks like FFT functions only, and sprc664 looks like it needs to be built on top on another library, maybe 'rts2800_fpu32.lib'.

Please help me figure out how to compile code targeting the FPU on the 28335. Is sprc530 updated? Is there a new version of 'rts2800_fpu32.lib'?

Thanks heaps for helping out.

Regards,

Clark,

Which CGT version are you using? You need at least 5.x to get support for the F28335. These versions also contain rts2800_fpu32.lib. And in the compiler you can activate float support via the --float_support=fpu32 option.
