SPI Configuration Structure definition
Syntax
Fields
CRCPolynomial
Specifies the polynomial used for the CRC calculation. This parameter must be an odd number between Min_Data = 1 and Max_Data = 65535. Read more...
Mode
Specifies the SPI operating mode. This parameter can be a value of SPI_Mode. Read more...
Direction
Specifies the SPI bidirectional mode state. This parameter can be a value of SPI_Direction. Read more...
DataSize
Specifies the SPI data size. This parameter can be a value of SPI_Data_Size. Read more...
CLKPolarity
Specifies the serial clock steady state. This parameter can be a value of SPI_Clock_Polarity. Read more...
CLKPhase
Specifies the clock active edge for the bit capture. This parameter can be a value of SPI_Clock_Phase. Read more...
NSS
Specifies whether the NSS signal is managed by hardware (NSS pin) or by software using the SSI bit. This parameter can be a value of SPI_Slave_Select_management. Read more...
BaudRatePrescaler
Specifies the Baud Rate prescaler value which will be used to configure the transmit and receive SCK clock. This parameter can be a value of SPI_BaudRate_Prescaler. Read more...
FirstBit
Specifies whether data transfers start from MSB or LSB bit. This parameter can be a value of SPI_MSB_LSB_transmission. Read more...
TIMode
Specifies if the TI mode is enabled or not. This parameter can be a value of SPI_TI_mode. Read more...
CRCCalculation
Specifies if the CRC calculation is enabled or not. This parameter can be a value of SPI_CRC_Calculation. Read more...
