Functions
void	SPI_Inizialize (void)
	SPI is initialized here. Its ise t at 8 bits and 100 KHz, as default.
void	SPI_callback (uint32_t event)
	After that the SPI ends its operations and the interrupt is generated this signal function is called which marks errors, if any and flags of operation done.
void	SPI_Inizialize_per_il_DAC (void)
	SPI is initialized here for DAC. Remember to set the variable SPI_speed before the call. This function is becoming obsolote.
void	SPItx (unsigned char dato)
	This is a blocking function that transmits one byte over the SPI.
void	SPItx_16_per_il_DAC (uint16_t dato)
unsigned char	SPIrx (void)
unsigned long int	SPIrx24 (void)

Variables
ARM_DRIVER_SPI	Driver_SPI2
ARM_DRIVER_SPI *	SPIdrv
uint32_t	evento_SPI
	This is the variable which resembles the flags from the communication.
uint32_t	SPI_speed
	The speed to be set to SPI. It could varies from chip to chip.
int32_t	status
