Detailed Description

Configuration structure of the SPI master driver instance.

Field Documentation

uint8_t nrfx_spi_config_t::miso_pin

MISO pin number (optional).

Set to NRFX_SPI_PIN_NOT_USED if this signal is not needed.

uint8_t nrfx_spi_config_t::mosi_pin

MOSI pin number (optional).

Set to NRFX_SPI_PIN_NOT_USED if this signal is not needed.

uint8_t nrfx_spi_config_t::orc

Overrun character.

This character is used when all bytes from the TX buffer are sent, but the transfer continues due to RX.

uint8_t nrfx_spi_config_t::ss_pin

Slave Select pin number (optional).

Set to NRFX_SPI_PIN_NOT_USED if this signal is not needed. The driver supports only active low for this signal. If the signal must be active high, it must be controlled externally.
