How to read byte from SPI?

[ATeli.1]

There is some way to read directly the byte that are send via SPI and not the int8 that is generate by the function?

int8_t buffer[BUFFER_SIZE]
 
HAL_SPI_RECEIVE_DMA(...,(uint8_t*)buffer,...,...)

Yes, see the low level (LL) functions. LL_SPI_ReceiveData8, LL_SPI_ReceiveData16
