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 channel.

Note:

LL_DAC_Init() aims to ease basic configuration of a DAC channel. Leaving it ready to be enabled and output: a level by calling one of LL_DAC_ConvertData12RightAligned LL_DAC_ConvertData12LeftAligned LL_DAC_ConvertData8RightAligned or one of the supported autogenerated wave.

This function allows configuration of:

• Output mode
• Trigger
• Wave generation

The setting of these parameters by function LL_DAC_Init() is conditioned to DAC state: DAC channel 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
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
