Hi,

I need an example of real time FFT from online ADC signal based on RM-XX series launchpad.

Thank you for your help and reply.

    Hi Amin,

    TI Cortex-R4 DSP (CMSIS) library includes 60+ functions covering fourier transforms and many other frequently used DSP algorithms. Most algorithms are available in floating-point and various fixed-point formats and are optimized for the Cortex-R series processors.

    Hi QJ,
    Thanks for your help. This sample code(real time fft for ADC signal) does not exist.
    For example, one of the sample project based on 2837xD processor is:
    controlSUITE—>libs—>dsp—>FPU—>v1_50—>exp.—>fft—>2837xD_rfft_adc_rt
    but, in the CMSIS library there are fft code based on pre-loaded data.
    Best regards,
    Amin
