Typedefs
typedef enum SPI_MODE	SPI_MODE
	Clock polarity and phase If CPOL=0, base value of the clock is zero If CPOL=1, base value of the clock is one If CPHA=0, sample on leading (first) clock edge If CPHA=1, sample on trailing (second) clock edge.
typedef enum SPI_SS_POLARITY	SPI_SS_POLARITY
	Slave select polarity (output from master)
typedef enum SPI_ENDIAN	SPI_ENDIAN
	SPI Endian: Direction of bit data flow (MSB or LSB first).
typedef enum SPI_SS_MODE	SPI_SS_MODE
	For all the available GPIO config combinations (spiGpioCfg) for master and slave modes, please reference the User Documentation, since the values vary by hardware platform. More...

Enumerations
enum	{ SPI_MASTER_ROLE = 1, SPI_SLAVE_ROLE = 2 }

enum	SPI_SS_MODE { SPI_SS_NORMAL, SPI_SS_INACTIVE_BTW_BYTES }
	For all the available GPIO config combinations (spiGpioCfg) for master and slave modes, please reference the User Documentation, since the values vary by hardware platform. More...

enum	SPIFFY_STATUS { SPIFFY_SUCCESS, SPIFFY_SLAVE_NOT_ENOUGH_RX_FIFO_BYTES }

Functions
void	wiced_hal_pspi_init (uint8_t devRole, uint32_t clkSpeed, SPI_ENDIAN endian, SPI_SS_POLARITY polarity, SPI_MODE mode)
	Initialize the SPI driver with the given parameters. More...
void	wiced_hal_pspi_tx_data (uint32_t txLen, const uint8_t *txBuf)
	Send/transmit data over SPI as the master. More...
