ErrorStatus LL_DAC_DeInit

(

DAC_TypeDef *

DACx

)

De-initialize registers of the selected DAC instance to their default reset values.

Parameters:

DACx	DAC instance

Return values:

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

ErrorStatus LL_DAC_Init	(	DAC_TypeDef *	DACx,
		uint32_t	DAC_Channel,
		LL_DAC_InitTypeDef *	DAC_InitStruct
	)

Initialize some features of DAC instance.

Note:

The setting of these parameters by function LL_DAC_Init() is conditioned to DAC state: DAC instance must be disabled.

Parameters:

DACx	DAC instance
DAC_Channel	This parameter can be one of the following values: LL_DAC_CHANNEL_1 LL_DAC_CHANNEL_2 (1) (1) On this STM32 serie, parameter not available on all devices. Refer to device datasheet for channels availability.
DAC_InitStruct	Pointer to a LL_DAC_InitTypeDef structure

Return values:

An	ErrorStatus enumeration value: SUCCESS: DAC registers are initialized ERROR: DAC registers are not initialized

void LL_DAC_StructInit

(

LL_DAC_InitTypeDef *

DAC_InitStruct

)

Set each LL_DAC_InitTypeDef field to default value.

Parameters:

DAC_InitStruct

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

Return values:

None
