uint32_t HAL_DACEx_DualGetValue ( DAC_HandleTypeDef * hdac )

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

Parameters:

hdac	pointer to a DAC_HandleTypeDef structure that contains the configuration information for the specified DAC.

Return values:

The	selected DAC channel data output value.

uint32_t HAL_DACEx_GetTrimOffset	(	DAC_HandleTypeDef *	hdac,
		uint32_t	Channel
	)

Return the DAC trimming value.

Parameters:

hdac	DAC handle
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:

Trimming value : range: 0->31

HAL_StatusTypeDef HAL_DACEx_SelfCalibrate	(	DAC_HandleTypeDef *	hdac,
		DAC_ChannelConfTypeDef *	sConfig,
		uint32_t	Channel
	)

Run the self calibration of one DAC channel.

Parameters:

hdac	pointer to a DAC_HandleTypeDef structure that contains the configuration information for the specified DAC.
sConfig	DAC channel configuration structure.
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:

Updates	DAC_TrimmingValue. , DAC_UserTrimming set to DAC_UserTrimming
HAL	status

Note:: Calibration runs about 7 ms.

		DAC_ChannelConfTypeDef *	sConfig,
		uint32_t	Channel,
		uint32_t	NewTrimmingValue
	)

Set the trimming mode and trimming value (user trimming mode applied).

Parameters:

hdac	pointer to a DAC_HandleTypeDef structure that contains the configuration information for the specified DAC.
sConfig	DAC configuration structure updated with new DAC trimming value.
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
NewTrimmingValue	DAC new trimming value

Return values:

HAL status
