Function Documentation

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

Configures the selected DAC channel.

Note:

By calling this function, the high frequency interface mode (HFSEL bits) will be set. This parameter scope is the DAC instance. As the function is called for each channel, the DAC_HighFrequency of

• sConfig must be the same at each call. (or DAC_HIGH_FREQUENCY_INTERFACE_MODE_AUTOMATIC self detect).

Parameters:

hdac	pointer to a DAC_HandleTypeDef structure that contains the configuration information for the specified DAC.
sConfig	DAC 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 (Whenever present)

Return values:

uint32_t HAL_DAC_GetValue	(	DAC_HandleTypeDef *	hdac,
		uint32_t	Channel
	)

Returns 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.
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.
