MSP430FR6043: 32-bit complex FFT with LEA example

Part Number: MSP430FR6043


Asking on behalf of my customer:

We are implementing an algorithm on the MSP430 platform. This algorithm has to perform a complex 256 point FFT with 32 bit precision.

Looking at what is provided in the DSPLib we can make this work with the FFT function provided by TI but only with disabled LEA
This method is not recommended for production according to your documentation.

Can you provide an example of processing a 32 bit complex FFT using LEA?

The 32 bit example in the DSPLIb is not for a complex FFT

Thanks in advance,

/ Wolfgang, EP FAE
