Field Documentation

uint16_t SPI_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

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

Definition at line 75 of file stm32f4xx_spi.h.

uint16_t SPI_CPHA

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

Definition at line 68 of file stm32f4xx_spi.h.

uint16_t SPI_CPOL

Specifies the serial clock steady state. This parameter can be a value of SPI_Clock_Polarity

Definition at line 65 of file stm32f4xx_spi.h.

uint16_t SPI_CRCPolynomial

Specifies the polynomial used for the CRC calculation.

Definition at line 84 of file stm32f4xx_spi.h.

uint16_t SPI_DataSize

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

Definition at line 62 of file stm32f4xx_spi.h.

uint16_t SPI_Direction

Specifies the SPI unidirectional or bidirectional data mode. This parameter can be a value of SPI_data_direction

Definition at line 56 of file stm32f4xx_spi.h.

uint16_t SPI_FirstBit

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

Definition at line 81 of file stm32f4xx_spi.h.

uint16_t SPI_Mode

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

Definition at line 59 of file stm32f4xx_spi.h.

uint16_t SPI_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
