10.2 SPI1 Master Programming Example
The following code shows how to initialize SPI1 as a master, write a byte to a SPI slave, and read a byte from a SPI slave.
#include "wiced_hal_gpio.h"
#include "wiced_hal_pspi.h"
#define SPIFFY_SPEED 1000000 /* Use 1M speed */
#define SPIFFY_CS_ASSERT 1
#define SPIFFY_CS_DEASSSERT 0
uint8_t test_spiffy1_master_send_receive_byte( uint8_t byteToSend );
void test_pspi_driver( void )
{
/* Reset spi hardware block and set to default config*/
wiced_hal_pspi_reset( );
/* Initialize spiffy1 in master role */
/* available pin combinations are in spiffydriver.h */
