Macros
#define	RFLPC_SPI_CPOL_RISING_EDGE   0
	Configure SCL to generate a rising edge clock. More...
#define	RFLPC_SPI_CPOL_FALLING_EDGE   2
	Configure SCL to generate a falling edge clock. More...
#define	RFLPC_SPI_CPHA_PHASE_PIOR_TO_FIRST_EDGE   0
	Transmit data before first clock edge. More...
#define	RFLPC_SPI_CPHA_PHASE_FIRST_EDGE   1
	Transmit data at first clock edge. More...

Enumerations
enum	rflpc_spi_t {   RFLPC_SPI0,   RFLPC_SPI1 }
	Used to select which SPI port to use. More...
enum	rflpc_spi_mode_t {   RFLPC_SPI_MASTER,   RFLPC_SPI_SLAVE }
	Used to select the SPI operating mode. More...

Functions
void	rflpc_spi_init (rflpc_spi_t port, rflpc_spi_mode_t mode, rflpc_clock_divider_t cpu_clock_divider, uint8_t data_size_transfert, uint8_t clock_prescale, uint8_t serial_clock_rate, uint8_t clock_polarity_phase)
	Inits the SPI interface in master mode. More...
static LPC_SSP_TypeDef *	rflpc_spi_get_base_addr (rflpc_spi_t port)
	Returns the base address of the SPI control block depending of the desired port. More...
static int	rflpc_spi_tx_fifo_empty (rflpc_spi_t port)
	Tests if transmition FIFO is empty. More...
static int	rflpc_spi_idle (rflpc_spi_t port)
	Test if the spi is idle (nor transmiting neither receiving) This is useful when you need to handle CS by hand. More...
static int	rflpc_spi_tx_fifo_full (rflpc_spi_t port)
	Tests if the transmition FIFO is full. More...
static int	rflpc_spi_rx_fifo_empty (rflpc_spi_t port)
	Tests if the reception FIFO is empty. More...
static void	rflpc_spi_write (rflpc_spi_t port, uint16_t data)
	Sends data through the spi interface. More...
static uint16_t	rflpc_spi_read (rflpc_spi_t port)
	Receive data through the spi interface. More...
void	rflpc_spi_set_rx_callback (rflpc_spi_t port, rflpc_irq_handler_t callback)
	Sets the interrupt handler for SPI reception. More...
