Function Documentation

void DAC_DMACmd ( uint32_t  DAC_Channel,
FunctionalState  NewState 
)

Enables or disables the specified DAC channel DMA request.

Note
When enabled DMA1 is generated when an external trigger (EXTI Line9, TIM2, TIM4, TIM5, TIM6, TIM7 or TIM8 but not a software trigger) occurs.
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
NewState,:new state of the selected DAC channel DMA request. This parameter can be: ENABLE or DISABLE.
Note
The DAC channel1 is mapped on DMA1 Stream 5 channel7 which must be already configured.
The DAC channel2 is mapped on DMA1 Stream 6 channel7 which must be already configured.
Return values
None
