MSP430FR5994: Is there any micro controller/ Evolution Board/ Launchpad which has implemented FFT/FIR/IIR filter in C language?

Part Number: MSP430FR5994

Dear sir,

i am using launchpad of MSP430FR5994. Now i have seen example  BOOSTXL_AUDIO project  which has implemented FFT in assembly language. Is there any launchpad/evolution board which has implemented FFT in C language ? Looking for your suggestion

Thanks and Regards,
