Regular Channels DMA Configuration functions. More...

Functions

void ADC_DMACmd (ADC_TypeDef *ADCx, FunctionalState NewState)
 Enables or disables the specified ADC DMA request.
void ADC_DMAConfig (ADC_TypeDef *ADCx, uint32_t ADC_DMAMode)
 Configure ADC DMA mode.

Detailed Description

Regular Channels DMA Configuration functions. 

 ===============================================================================
                   ##### Regular Channels DMA Configuration functions #####
 ===============================================================================  

  [..] This section provides functions allowing to configure the DMA for ADC regular 
  channels. Since converted regular channel values are stored into a unique data register, 
  it is useful to use DMA for conversion of more than one regular channel. This 
  avoids the loss of the data already stored in the ADC Data register. 
  
  (#) ADC_DMACmd() function is used to enable the ADC DMA mode, after each
      conversion of a regular channel, a DMA request is generated.
  (#) ADC_DMAConfig() function is used to select between the one shot DMA mode 
      or the circular DMA mode

Function Documentation

void ADC_DMACmd ( ADC_TypeDef *  ADCx,
FunctionalState  NewState 
)

Enables or disables the specified ADC DMA request.

Parameters:
ADCx,:where x can be 1, 2, 3 or 4 to select the ADC peripheral.
NewState,:new state of the selected ADC DMA transfer. This parameter can be: ENABLE or DISABLE.
Return values:
None

void ADC_DMAConfig ( ADC_TypeDef *  ADCx,
uint32_t  ADC_DMAMode 
)

Configure ADC DMA mode.

Parameters:
ADCx,:where x can be 1, 2, 3 or 4 to select the ADC peripheral.
ADC_DMAMode,:select the ADC DMA mode. This parameter can be one of the following values:

  • ADC_DMAMode_OneShot: ADC DMA Oneshot mode
  • ADC_DMAMode_Circular: ADC DMA circular mode
Return values:
None
