Detailed Description

The context structure for storing driver configuration. User shall define the values stored within.

Warning

The following example describes how to fill a spi_master_config_t structure. Take into consideration that different hardware might not have the same pins. Make sure to accommodate pin name based on your hardware specifics.

Example

// SPI Master configuration structure.
spi_master_config_t spi_master_config;
 
// Specify desired SPI Serial Clock pin.
spi_master_config.sck = MIKROBUS_1_SCK;
 
// Specify desired SPI Master-In Slave-Out pin.
spi_master_config.miso = MIKROBUS_1_MISO;
 
// Specify desired SPI Master-Out Slave-In pin.
spi_master_config.mosi = MIKROBUS_1_MOSI;
 
// Specify desired SPI transfer rate.
spi_master_config.speed = 100000;
 
// Specify desired SPI Mode.
spi_master_config.mode = SPI_MASTER_MODE_0;
 
// Specify SPI default write data.
spi_master_config.default_write_data = 0x00;
