Detailed Description

Initialization and de-initialization functions.

 ===============================================================================
              ##### Initialization and de-initialization functions #####
 ===============================================================================
    [..]  This subsection provides a set of functions allowing to initialize and
          de-initialize the SPIx peripheral:

      (+) User must implement hal_spi_msp_init() function in which he configures
          all related peripherals resources (GPIO, DMA, IT and NVIC ).

      (+) Call the function hal_spi_init() to configure the selected device with
          the selected configuration:
        (++) Direction
        (++) Data Size
        (++) Clock Polarity and Phase
        (++) BaudRate Prescaler
        (++) TIMode
        (++) Slave Select

      (+) Call the function hal_spi_deinit() to restore the default configuration
          of the selected SPIx peripheral.

Function Documentation

hal_spi_deinit()

hal_status_t hal_spi_deinit

(

spi_handle_t *

p_spi

)

De-initialize the SPI peripheral.

Parameters

[in]

p_spi

Pointer to an SPI handle which contains the configuration information for the specified SPI module.

Return values

HAL_OK	Operation is OK.
HAL_ERROR	Parameter error or operation not supported.
HAL_BUSY	Driver is busy.
HAL_TIMEOUT	Timeout occurred.

hal_spi_init()

hal_status_t hal_spi_init

(

spi_handle_t *

p_spi

)

Initialize the SPI according to the specified parameters in the spi_init_t and initialize the associated handle.

Parameters

[in]

p_spi

Pointer to an SPI handle which contains the configuration information for the specified SPI module.

Return values

HAL_OK	Operation is OK.
HAL_ERROR	Parameter error or operation not supported.
HAL_BUSY	Driver is busy.
HAL_TIMEOUT	Timeout occurred.

hal_spi_msp_deinit()

void hal_spi_msp_deinit

(

spi_handle_t *

p_spi

)

De-initialize the SPI MSP.

Note

This function should not be modified. When the callback is needed, the hal_spi_msp_deinit can be implemented in the user file.

Parameters

[in]

p_spi

Pointer to an SPI handle which contains the configuration information for the specified SPI module.

hal_spi_msp_init()

void hal_spi_msp_init

(

spi_handle_t *

p_spi

)

Initialize the SPI MSP.

Note

This function should not be modified. When the callback is needed, the hal_spi_msp_deinit can be implemented in the user file.

Parameters

[in]

p_spi

Pointer to an SPI handle which contains the configuration information for the specified SPI module.

hal_spi_v2_deinit()

hal_status_t hal_spi_v2_deinit

(

spi_handle_t *

p_spi

)

De-initialize the SPI peripheral.

Parameters

[in]

p_spi

Pointer to an SPI handle which contains the configuration information for the specified SPI module.

Return values

HAL_OK	Operation is OK.
HAL_ERROR	Parameter error or operation not supported.
HAL_BUSY	Driver is busy.
HAL_TIMEOUT	Timeout occurred.

hal_spi_v2_init()

hal_status_t hal_spi_v2_init	(	spi_handle_t *	p_spi,
		uint32_t	rx_sample_delay
	)

Initialize the SPI according to the specified parameters in the spi_init_t and initialize the associated handle.

Parameters

[in]	p_spi	Pointer to an SPI handle which contains the configuration information for the specified SPI module.
[in]	rx_sample_delay	Receive sample delay [0, 7]

Return values

HAL_OK	Operation is OK.
HAL_ERROR	Parameter error or operation not supported.
HAL_BUSY	Driver is busy.
HAL_TIMEOUT	Timeout occurred.

hal_spi_v2_msp_deinit()

void hal_spi_v2_msp_deinit

(

spi_handle_t *

p_spi

)

De-initialize the SPI MSP.

Note

This function should not be modified. When the callback is needed, the hal_spi_msp_deinit can be implemented in the user file.

Parameters

[in]

p_spi

Pointer to an SPI handle which contains the configuration information for the specified SPI module.

hal_spi_v2_msp_init()

void hal_spi_v2_msp_init

(

spi_handle_t *

p_spi

)

Initialize the SPI MSP.

Note

This function should not be modified. When the callback is needed, the hal_spi_msp_deinit can be implemented in the user file.

Parameters

[in]

p_spi

Pointer to an SPI handle which contains the configuration information for the specified SPI module.
