Detailed Description

User needs to specifiy values herein.

Note

Take into consideration that any value can be changed explicitly by the user.

Example

// SPI Master configuration structure.
static hal_spi_master_config_t hal_spi_master_cfg;
 
// Populate structure to default init values.
hal_spi_master_configure_default(&hal_spi_master_cfg);
 
// Specify desired SPI Serial Clock pin.
hal_spi_master_cfg.sck = MIKROBUS_1_SCK;
 
// Specify desired SPI Master-In Slave-Out pin.
hal_spi_master_cfg.miso = MIKROBUS_1_MISO;
 
// Specify desired SPI Master-Out Slave-In pin.
hal_spi_master_cfg.mosi = MIKROBUS_1_MOSI;
 
// Specify desired SPI transfer rate.
hal_spi_master_cfg.speed = 100000;
 
// Specify desired SPI Mode.
hal_spi_master_cfg.mode = SPI_MASTER_MODE_0;
