Field Documentation

◆ BaudRatePrescaler

uint32_t SPI_InitTypeDef::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

Note: The communication clock is derived from the master clock. The slave clock does not need to be set.

◆ CLKPhase

uint32_t SPI_InitTypeDef::CLKPhase

Specifies the clock active edge for the bit capture. This parameter can be a value of SPI Clock Phase

◆ CLKPolarity

uint32_t SPI_InitTypeDef::CLKPolarity

Specifies the serial clock steady state. This parameter can be a value of SPI Clock Polarity

◆ CRCCalculation

uint32_t SPI_InitTypeDef::CRCCalculation

Specifies if the CRC calculation is enabled or not. This parameter can be a value of SPI CRC Calculation

◆ CRCLength

uint32_t SPI_InitTypeDef::CRCLength

Specifies the CRC Length used for the CRC calculation. This parameter can be a value of SPI CRC Length

◆ CRCPolynomial

uint32_t SPI_InitTypeDef::CRCPolynomial

Specifies the polynomial used for the CRC calculation. This parameter must be an odd number between Min_Data = 0 and Max_Data = 65535

◆ DataSize

uint32_t SPI_InitTypeDef::DataSize

Specifies the SPI data size. This parameter can be a value of SPI Data Size

◆ Direction

uint32_t SPI_InitTypeDef::Direction

Specifies the SPI bidirectional mode state. This parameter can be a value of SPI Direction Mode

◆ FifoThreshold

uint32_t SPI_InitTypeDef::FifoThreshold

Specifies the FIFO threshold level. This parameter can be a value of SPI Fifo Threshold

◆ FirstBit

uint32_t SPI_InitTypeDef::FirstBit

Specifies whether data transfers start from MSB or LSB bit. This parameter can be a value of SPI MSB LSB Transmission

◆ IOSwap

uint32_t SPI_InitTypeDef::IOSwap

Invert MISO/MOSI alternate functions This parameter can be a value of Control SPI IO Swap

◆ MasterInterDataIdleness

uint32_t SPI_InitTypeDef::MasterInterDataIdleness

Specifies minimum time delay (expressed in SPI clock cycles periods) inserted between two consecutive data frames in master mode. This parameter can be a value of SPI Master Inter-Data Idleness

◆ MasterKeepIOState

uint32_t SPI_InitTypeDef::MasterKeepIOState

Control of Alternate function GPIOs state This parameter can be a value of Keep IO State

◆ MasterReceiverAutoSusp

uint32_t SPI_InitTypeDef::MasterReceiverAutoSusp

Control continuous SPI transfer in master receiver mode and automatic management in order to avoid overrun condition. This parameter can be a value of SPI Master Receiver AutoSuspend

◆ MasterSSIdleness

uint32_t SPI_InitTypeDef::MasterSSIdleness

Specifies an extra delay, expressed in number of SPI clock cycle periods, inserted additionally between active edge of SS and first data transaction start in master mode. This parameter can be a value of SPI Master SS Idleness

◆ Mode

uint32_t SPI_InitTypeDef::Mode

Specifies the SPI operating mode. This parameter can be a value of SPI Mode

◆ NSS

uint32_t SPI_InitTypeDef::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

◆ NSSPMode

uint32_t SPI_InitTypeDef::NSSPMode

Specifies whether the NSSP signal is enabled or not . This parameter can be a value of SPI NSS Pulse Mode This mode is activated by the SSOM bit in the SPIx_CR2 register and it takes effect only if the SPI interface is configured as Motorola SPI master (FRF=0).

◆ NSSPolarity

uint32_t SPI_InitTypeDef::NSSPolarity

Specifies which level of SS input/output external signal (present on SS pin) is considered as active one. This parameter can be a value of SPI NSS Polarity

◆ RxCRCInitializationPattern

uint32_t SPI_InitTypeDef::RxCRCInitializationPattern

Specifies the receiver CRC initialization Pattern used for the CRC calculation. This parameter can be a value of SPI CRC Calculation Initialization Pattern

◆ TIMode

uint32_t SPI_InitTypeDef::TIMode

Specifies if the TI mode is enabled or not. This parameter can be a value of SPI TI Mode

◆ TxCRCInitializationPattern

uint32_t SPI_InitTypeDef::TxCRCInitializationPattern

Specifies the transmitter CRC initialization Pattern used for the CRC calculation. This parameter can be a value of SPI CRC Calculation Initialization Pattern
