ErrorStatus LL_SPI_DeInit ( SPI_TypeDef * SPIx )

De-initialize the SPI registers to their default reset values.

Parameters:

SPIx	SPI Instance

Return values:

An	ErrorStatus enumeration value: SUCCESS: SPI registers are de-initialized ERROR: SPI registers are not de-initialized

Definition at line 151 of file stm32l4xx_ll_spi.c.

Initialize the SPI registers according to the specified parameters in SPI_InitStruct.

Note:: As some bits in SPI configuration registers can only be written when the SPI is disabled (SPI_CR1_SPE bit =0), SPI IP should be in disabled state prior calling this function. Otherwise, ERROR result will be returned.

Parameters:

SPIx	SPI Instance
SPI_InitStruct	pointer to a LL_SPI_InitTypeDef structure

Return values:

An	ErrorStatus enumeration value. (Return always SUCCESS)

void LL_SPI_StructInit ( LL_SPI_InitTypeDef * SPI_InitStruct )

Set each LL_SPI_InitTypeDef field to default value.

Parameters:

SPI_InitStruct pointer to a LL_SPI_InitTypeDef structure whose fields will be set to default values.

Return values:

None
