TMS320F280049: Ask for FFT example

Part Number: TMS320F280049
Other Parts Discussed in Thread: C2000WARE,

Hi

I see C2000 can do FFT algorithm on

1. VCU

2. TMS320F387X FFT example：C:\ti\C2000Ware_1_00_06_00_Software\libraries\dsp\FPU\c28\examples\fft，

What's the difference? Do FFT by hardware or look-up table.

Based on TMS320F280049, which project example is the best to start?

The purpose is sampling ADC data, then do digital filtering and FFT calculation.

    Hi Daniel,

    You can start with this example C:\ti\C2000Ware_1_00_06_00_Software\libraries\dsp\FPU\c28\examples\fft\2837x_rfft_adc_rt

    This example samples the PWM signal via ADC and runs the FFT in real time. This example is for F2837x, you can change the device support to F280049 as use the same example as the FPU hardware is exactly same in both devices.
