LL_DAC_DeInit()

ErrorStatus LL_DAC_DeInit

(

const 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

LL_DAC_Init()

ErrorStatus LL_DAC_Init	(	DAC_TypeDef *	DACx,
		uint32_t	DAC_Channel,
		const 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 (1) (1) On this STM32 series, 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

Definition at line 177 of file stm32f4xx_ll_dac.c.

LL_DAC_StructInit()

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
