vsf_spi_init()

vsf_err_t vsf_spi_init	(	vsf_spi_t *	spi_ptr,
		vsf_spi_cfg_t *	cfg_ptr
	)

Initialize a SPI instance.

Parameters

[in,out]	spi_ptr	Pointer to SPI instance structure vsf_spi_t
[in]	cfg_ptr	Pointer to SPI configuration structure vsf_spi_cfg_t

Returns

vsf_err_t: VSF_ERR_NONE if initialization successful, otherwise returns error code

Note

The configuration includes clock settings, transfer modes, and interrupt handlers

This must be called before any other SPI operations except for vsf_spi_capability()
