Function Documentation

void DAC_Cmd	(	uint32_t	DAC_Channel,
		FunctionalState	NewState
	)

Enables or disables the specified DAC channel.

Parameters

DAC_Channel,:	The selected DAC channel. This parameter can be one of the following values: DAC_Channel_1: DAC Channel1 selected DAC_Channel_2: DAC Channel2 selected
NewState,:	new state of the DAC channel. This parameter can be: ENABLE or DISABLE.

Note: When the DAC channel is enabled the trigger source can no more be modified.

Return values

None

void DAC_DeInit ( void )

Deinitializes the DAC peripheral registers to their default reset values.

Parameters

None

Return values

None

void DAC_DualSoftwareTriggerCmd ( FunctionalState NewState )

Parameters

NewState,: new state of the DAC channels software triggers. This parameter can be: ENABLE or DISABLE.

Return values

None

uint16_t DAC_GetDataOutputValue ( uint32_t DAC_Channel )

Returns the last data output value of the selected DAC channel.

Parameters

DAC_Channel,:

The selected DAC channel. This parameter can be one of the following values:

DAC_Channel_1: DAC Channel1 selected
DAC_Channel_2: DAC Channel2 selected

Return values

The	selected DAC channel data output value.

void DAC_Init	(	uint32_t	DAC_Channel,
		DAC_InitTypeDef *	DAC_InitStruct
	)

Initializes the DAC peripheral according to the specified parameters in the DAC_InitStruct.

Parameters

DAC_Channel,:	the selected DAC channel. This parameter can be one of the following values: DAC_Channel_1: DAC Channel1 selected DAC_Channel_2: DAC Channel2 selected
DAC_InitStruct,:	pointer to a DAC_InitTypeDef structure that contains the configuration information for the specified DAC channel.

Return values

None

void DAC_SetChannel1Data	(	uint32_t	DAC_Align,
		uint16_t	Data
	)

Set the specified data holding register value for DAC channel1.

Parameters

DAC_Align,:	Specifies the data alignment for DAC channel1. This parameter can be one of the following values: DAC_Align_8b_R: 8bit right data alignment selected DAC_Align_12b_L: 12bit left data alignment selected DAC_Align_12b_R: 12bit right data alignment selected
Data,:	Data to be loaded in the selected data holding register.

Return values

None

void DAC_SetChannel2Data	(	uint32_t	DAC_Align,
		uint16_t	Data
	)

Set the specified data holding register value for DAC channel2.

Parameters

DAC_Align,:	Specifies the data alignment for DAC channel2. This parameter can be one of the following values: DAC_Align_8b_R: 8bit right data alignment selected DAC_Align_12b_L: 12bit left data alignment selected DAC_Align_12b_R: 12bit right data alignment selected
Data,:	Data to be loaded in the selected data holding register.

Return values

None

void DAC_SetDualChannelData	(	uint32_t	DAC_Align,
		uint16_t	Data2,
		uint16_t	Data1
	)

Set the specified data holding register value for dual channel DAC.

Parameters

DAC_Align,:	Specifies the data alignment for dual channel DAC. This parameter can be one of the following values: DAC_Align_8b_R: 8bit right data alignment selected DAC_Align_12b_L: 12bit left data alignment selected DAC_Align_12b_R: 12bit right data alignment selected
Data2,:	Data for DAC Channel2 to be loaded in the selected data holding register.
Data1,:	Data for DAC Channel1 to be loaded in the selected data holding register.

Note: In dual mode, a unique register access is required to write in both DAC channels at the same time.

Return values

None

void DAC_SoftwareTriggerCmd	(	uint32_t	DAC_Channel,
		FunctionalState	NewState
	)
