Field Documentation
uint32_t SPI_InitTypeDef::Mode
Specifies the SPI operating mode. This parameter can be a value of SPI_Mode
uint32_t SPI_InitTypeDef::Direction
Specifies the SPI bidirectional mode state. This parameter can be a value of
SPI_Direction
uint32_t SPI_InitTypeDef::DataSize
Specifies the SPI data size. This parameter can be a value of SPI_Data_Size
uint32_t SPI_InitTypeDef::CLKPolarity
Specifies the serial clock steady state. This parameter can be a value of
SPI_Clock_Polarity
uint32_t SPI_InitTypeDef::CLKPhase
Specifies the clock active edge for the bit capture. This parameter can be a value of
SPI_Clock_Phase
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
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
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
uint32_t SPI_InitTypeDef::TIMode
Specifies if the TI mode is enabled or not. This parameter can be a value of
SPI_TI_mode
uint32_t SPI_InitTypeDef::CRCCalculation
Specifies if the CRC calculation is enabled or not. This parameter can be a value of
SPI_CRC_Calculation
