TM4C129XKCZAD: simple FFT algorithm sample

Marvn Arcangel

Part Number: TM4C129XKCZAD

Hi Experts,

Our customer is new to programming and would like a piece of advice in creating a simple FFT spectrum analyzer with a maximum frequency of 100 kHz using development kit DK-TM4C129XNCZAD.

Maybe a simple example would help the customer.

In addition, he is also looking for a simple FFT library for DK-TM4C129XNCZAD. I searched the forum regarding this and I found this thread that points to this application note. will this help?

Thank you.

Regards,

Marvin

Hi Marvin,

Yes, there are many examples that the customer can reference. Please first have the customer download TivaWare SDK from https://www.ti.com/tool/SW-TM4C. Once downloaded, go to C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\dk-tm4c129x where you will find many examples for the DK-TM4C129X board. I will suggest to start with the blinky example or the hello example.

TivaWare does not have FFT examples. But the thread and app note you refer to is a good place to start although it may be a bit outdated.

Hi Charles,

This certainly helps. However, do we have an updated application note that describes the process using the latest Code Composer Studio?

Thank you.
