Part Number: MSP430FR5994

Tool/software: Code Composer Studio

Dear team,

I am using the following example code and MSP430FR5994.

But i felt confused with this example. Could anyone tell me how to FFT Calculation in this example?

Please tell me more information about this example.

    Hi Susan,

    There a few resources that you can use to help you to understand the example and how to implement a real-time FFT on the MSP430 in general. Please refer to the DSPLib User's Guide (found within the MSP430Ware->dsplib directory) in order to see all of the APIs and functions associated with the digital signal processing library.

    Another resource to use which actually walks you through how the FFT operates and is implemented on the MCU using LEA is the Filtering and signal processing reference design using MSP430 FRAM microcontroller. This TIDesign steps you through the theory and implementation of performing a real-time FFT and also provides source code to show users exactly how the DSPLib functions are used to accomplish FFT & FIR filtering using the library.

    Hopefully this helps point you in the right direction!

    Best regards,

    Matt
