TwiddleCoeff beyont 512 bins for FFT algorithm

[Kyriakos]

Hi all,
Is it possible to run the FFT algorithm beyond the 512 points? for instance 1024 points or better 2048?

Thanks in advance

Hi,

Well, this depends on the MCU memory.
Which MCU are you using ?

Hi,
I am using PIC32MX795F512L (128Kb Ram).

Thanks and Regards,

Hello

I would also be interested in a 1024 or 2048 twiddle table.

Best regards

Hi,

I have successfully compiled FFT example with Twiddle array of 2048 elements, so it should work.

That is great Filip!

Do you think you could post the twiddle array?

Hi,

I don't have the exact tool for generating twiddle factors, I have just copied array of 512 elements 4 times in order to get array of 2048, to see if this compiles OK.

Filip.
