Detailed Description

Layer providing compatibility with the former API.

Typedef Documentation

typedef void(* nrf_drv_spis_event_handler_t)(nrf_drv_spis_event_t event)

SPI slave event callback function type.

Parameters

[in]

event

SPI slave driver event.

Function Documentation

ret_code_t nrf_drv_spis_init	(	nrf_drv_spis_t const *const	p_instance,
		nrf_drv_spis_config_t const *	p_config,
		nrf_drv_spis_event_handler_t	event_handler
	)

Function for initializing the SPI slave driver instance.

Note

When the nRF52 Anomaly 109 workaround for SPIS is enabled, this function initializes the GPIOTE driver as well, and uses one of GPIOTE channels to detect falling edges on CSN pin.

Parameters

[in]	p_instance	Pointer to the driver instance structure.
[in]	p_config	Pointer to the structure with the initial configuration. If NULL, the default configuration will be used.
[in]	event_handler	Function to be called by the SPI slave driver upon event.

Return values

NRF_SUCCESS	If the initialization was successful.
NRF_ERROR_INVALID_PARAM	If an invalid parameter is supplied.
NRFX_ERROR_INVALID_STATE	If the instance is already initialized.
NRF_ERROR_BUSY	If some other peripheral with the same instance ID is already in use. This is possible only if PERIPHERAL_RESOURCE_SHARING_ENABLED is set to a value other than zero.
NRF_ERROR_INTERNAL	GPIOTE channel for detecting falling edges on CSN pin cannot be initialized. Possible only when using nRF52 Anomaly 109 workaround.
