Hi Matine ,

you can use 2 or more spis' or i2cs' by using spi class, or i2c class respectively and see PeripheralPins.c PinNames.h for details.

Also, see the pinout of NucleoF767ZI.

PeripheralPins.c PinNames.h

eg.

SPI m_spi(SPI_MOSI, SPI_MISO, SPI_SCK);

SPI spi4(PE_14,PE_13,PE_12,PE_11); which includes slave select also
