HAL_DAC_GetValue()

uint32_t HAL_DAC_GetValue	(	const DAC_HandleTypeDef *	hdac,
		uint32_t	Channel )

#include <stm32f4xx_hal_dac.h>

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.
