CCS/TMS320F28377D: Real time FFT using F28377D eval board

venkat narayana
Intellectual 260 points
Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hai,

I am using F2837X control card R1_1. I want to do real time FFT on the ADC data. Upto this point I have completed using the reference software RFFT_adc_f32.

Now I want to modify / remove some of the frequency components of the output of RFFT_adc_f32 and then I want to do the IFFT on the modified RFFT result and then give it to DAC.

But I am unable to do the same. For IFFT I have seen the code ICFFT_f32 but unable to integrate the RFFT data to ICFFT.

Please help me solve this

Regards

Venkat

    Hi Venkat,

    Thanks for your question. Currently, you will not be able to perform inverse RFFT function for the same reason you mentioned

    For this, you need a 'pack function' which has not been released in the present version of the library. Also, an example of IRFFT is under development and will be released in one of the future versions of the library along with C2000Ware.
    I cannot give you an exact timeline of the release but you may check for the same in the new releases.
