MPC5775 SPT FFT

ronliu — Thu, 07 Jul 2016 06:20:01 GMT

HI all,

I'd like to use the SPT module. We can see that there is a FFT core in the SPT. But what should I do to make it work ? Is there some code sample to share? Thanks

Regards,

Ron

Hi Ron,

unfortunately, we do not have any example, how to use FFT core. I also had asked our application engineer about some app notes or documents, but I got the answer there no such documents.

This module is too complex to create some simple example. Solutions are created exactly for user application. You can order professional support service, which helps you to create the application. Please look at the following URL:

The attachment is the example project in GHS for MPC5775K. It demonstrate how to use SPT to do a 256 FFT.

Maybe you already got that. It's the only example code for FFT at this moment.
