Function Documentation

void DAC_DMACmd	(	DAC_TypeDef *	DACx,
		uint32_t	DAC_Channel,
		FunctionalState	NewState
	)

Enables or disables the specified DAC channel DMA request. When enabled DMA1 is generated when an external trigger (EXTI Line9, TIM2, TIM4, TIM6, TIM7 or TIM9 but not a software trigger) occurs.

Parameters

DACx,:	where x can be 1 or 2 to select the DAC peripheral.
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 selected DAC channel DMA request. This parameter can be: ENABLE or DISABLE.

Note

The DAC channel1 (channel2) is mapped on DMA1 channel3 (channel4) which must be already configured.

Return values

None
