CCS/TMS320F28335: Example code for Real time FFT using ADC

Muhammad Subhani

Part Number: TMS320F28335
Other Parts Discussed in Thread: C2000WARE, CONTROLSUITE

Tool/software: Code Composer Studio

Hi all,

I recently installed the latest versions of code composer studio (v8) and C2000ware. I looked up the example code section for realtime FFT using ADC and found example codes for F2837x.

I wanted to know where can I find the example codes for F28335.

Further, can I use the F2837x codes for F28335 without any modification? if not, what do I need to modify in these codes?

Regards,

    Muhammad,

    You can use the code without any modification, except you will have to start with a 28335 project (system files etc.) and then modify the Linker command file accordingly to accommodate the FFT sections. Typically this is straightforward - you will look at the 2837x linker command file, identify the FFT sections (input, output, coeff buffers etc.), and place them in appropriate memory sections in the 28335 memory map.

    FYI, we have a 28335 FFT-ADC example in ControlSUITE (the SW we released prior to C2000Ware). You can use that as reference.

    Please mark the issue as Answer Verified if this answers your question.
    Thanks,

    Thank you SIra

    Currently I am downloading ControlSUITE. I will try both methods.

    Thanks again
