Function Documentation

void DAC_ClearFlag	(	uint32_t	DAC_Channel,
		uint32_t	DAC_FLAG
	)

Clears the DAC channel's pending flags.

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_FLAG	specifies the flag to clear. This parameter can be of the following value: DAC_FLAG_DMAUDR: DMA underrun flag

Note

The DMA underrun occurs when a second external trigger arrives before the acknowledgement for the first external trigger is received (first request).

Return values

None

Definition at line 625 of file stm32f4xx_dac.c.

void DAC_ClearITPendingBit	(	uint32_t	DAC_Channel,
		uint32_t	DAC_IT
	)

Clears the DAC channel's interrupt pending bits.

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_IT	specifies the DAC interrupt pending bit to clear. This parameter can be the following values: DAC_IT_DMAUDR: DMA underrun interrupt mask

Note

The DMA underrun occurs when a second external trigger arrives before the acknowledgement for the first external trigger is received (first request).

Return values

None

Definition at line 688 of file stm32f4xx_dac.c.

FlagStatus DAC_GetFlagStatus	(	uint32_t	DAC_Channel,
		uint32_t	DAC_FLAG
	)

Checks whether the specified DAC flag is set or not.

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_FLAG	specifies the flag to check. This parameter can be only of the following value: DAC_FLAG_DMAUDR: DMA underrun flag

Note

The DMA underrun occurs when a second external trigger arrives before the acknowledgement for the first external trigger is received (first request).

Return values

The	new state of DAC_FLAG (SET or RESET).

Definition at line 590 of file stm32f4xx_dac.c.

ITStatus DAC_GetITStatus	(	uint32_t	DAC_Channel,
		uint32_t	DAC_IT
	)

Checks whether the specified DAC interrupt has occurred or not.

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_IT	specifies the DAC interrupt source to check. This parameter can be the following values: DAC_IT_DMAUDR: DMA underrun interrupt mask

Note

The DMA underrun occurs when a second external trigger arrives before the acknowledgement for the first external trigger is received (first request).

Return values

The	new state of DAC_IT (SET or RESET).

Definition at line 648 of file stm32f4xx_dac.c.

void DAC_ITConfig	(	uint32_t	DAC_Channel,
		uint32_t	DAC_IT,
		FunctionalState	NewState
	)

Enables or disables the specified DAC interrupts.

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_IT	specifies the DAC interrupt sources to be enabled or disabled. This parameter can be the following values: DAC_IT_DMAUDR: DMA underrun interrupt mask

Note

The DMA underrun occurs when a second external trigger arrives before the acknowledgement for the first external trigger is received (first request).

Parameters

NewState

new state of the specified DAC interrupts. This parameter can be: ENABLE or DISABLE.

Return values

None
