Detailed Description

SPI peripheral device configuration data.

Field Documentation

◆ miso_pin

uint32_t nrfx_spis_config_t::miso_pin

SPI MISO pin (optional).

Set NRFX_SPIS_PIN_NOT_USED if this signal is not needed.

◆ mosi_pin

uint32_t nrfx_spis_config_t::mosi_pin

SPI MOSI pin (optional).

Set NRFX_SPIS_PIN_NOT_USED if this signal is not needed.

◆ skip_gpio_cfg

bool nrfx_spis_config_t::skip_gpio_cfg

Skip GPIO configuration of pins.

When set to true, the driver does not modify any GPIO parameters of the used pins. Those parameters are supposed to be configured externally before the driver is initialized.

◆ skip_psel_cfg

bool nrfx_spis_config_t::skip_psel_cfg

Skip pin selection configuration.

When set to true, the driver does not modify pin select registers in the peripheral. Those registers are supposed to be set up externally before the driver is initialized.

Note: When both GPIO configuration and pin selection are to be skipped, the structure fields that specify pins can be omitted, as they are ignored anyway.

The documentation for this struct was generated from the following file:
