Hi, I using an 320vc5410 with external adc ad 1Msample and 8 bit resolution, and reserving 1024 memory space, need to run fft function.

Is there documentation where I can read for having more information on "ti site" about using this kind of function?

I remember you that I am starting from scratch.

Thanks in advance and best regards.

    Augusto,

    You might want to try the DSPLIB examples.  You can get DSPLIB for the 54xx series at:

    http://www.ti.com/tool/sprc099.

    I recently started working with the C5515 and found the rfft example in the c55xx library very useful.  There should be something similar in the c54xx library.

    Warning - there are some issues with the alignment of buffers that don't affect the examples, but may affect an application.  See the following thread for a discussion:
