TMS320F280040: Step to step Guide for FFT Implementation using C2000ware on a C2000 real-time MCU

Merlin Duty1

Part Number: TMS320F280040
Other Parts Discussed in Thread: C2000WARE

Dear people of the E2E Forum,

currently I am working on a project, where I need to implement an FFT on a C2000 real-time MCU.
(Using Code Composer and C2000ware examples)

If I take my time I will be able to work myself through the documentation and make it work.

However, does anybody of you maybe know of a step to step guide for implementing FFT with composer studio using the examples of C2000ware?

I am rather sure this is a very common thing to do, so I thought maybe someone made a tutorial of it. (Why inventing the bicycle anew?)
A simple step to step guide would save me lots of effort.

Looking forward to some community answers
Tell me if such a question is not really to be asked in this forum

Best regards

Merlin,

We have numerous Floating point FFT examples in C2000Ware at \libraries\dsp\FPU\c28\examples\fft

The user guide in \libraries\dsp\FPU\c28\docs will help, but the source code with its comments is what you really want to look at.

These examples work as is on the F2837x, but they can easily be ported to F28004x devices as well.

Thanks,

Sira

Hello sira,

thank you for the reply.

Is there any Guide on how to Port to F2800 ?

Best regards

No there isn't, but it straightforward. You can start with a F28004x example, then pull in the FFT source files and manage any dependencies. Also suitably modify the F28004x linker cmd files by placing the FFT sections in memory appropriately.

Thanks,

Sira
