Hello @OsBo
UltrasoundFFT.exe is the software tool to be used together with the proper UltrasoundFFT firmware installed on the STM32. X-CUBE-MEMSMIC1 contains different examples and supports different combinations of NUCLEO, X-NUCLEO and STEVAL boards.
UltrasoundFFT demo is available for NUCLEO-L476RG + X-NUCLEO-AMICAM1, NUCLEO-L4R5ZI + X-NUCLEO-AMICAM1 and STEVAL-STWINKT1B only. There is no support for NUCLEO-F401RE + X-NUCLEO-AMICAM1.
To use X-NUCLEO-AMICAM1 safely, read carefully hardware configuration needed. I suggest you to have a look to UM1901 chapter 2.8 and UM2649.
Best regards
Simone
