Detailed Description

Initialization and Configuration functions. 

 ===============================================================================
            ##### Initialization and Configuration functions #####
 ===============================================================================
    [..] This subsection provides functions allowing to initialize the DMA channel 
         source and destination addresses, incrementation and data sizes, transfer 
         direction, buffer size, circular/normal mode selection, memory-to-memory 
         mode selection and channel priority value.
    [..] The DMA_Init() function follows the DMA configuration procedures as described 
         in reference manual (RM0091).

Function Documentation

void DMA_Cmd ( DMA_Channel_TypeDef *  DMAy_Channelx,
FunctionalState  NewState 
)

Enables or disables the specified DMAy Channelx.

Parameters
DMAy_Channelx,:where y can be 1 to select the DMA and x can be 1 to 5 for DMA1 to select the DMA Channel.
NewState,:new state of the DMAy Channelx. This parameter can be: ENABLE or DISABLE.
Return values
None
void DMA_DeInit ( DMA_Channel_TypeDef *  DMAy_Channelx)

Deinitializes the DMAy Channelx registers to their default reset values.

Parameters
DMAy_Channelx,:where y can be 1 to select the DMA and x can be 1 to 5 for DMA1 to select the DMA Channel.
Return values
None
void DMA_Init ( DMA_Channel_TypeDef *  DMAy_Channelx,
DMA_InitTypeDef *  DMA_InitStruct 
)

Initializes the DMAy Channelx according to the specified parameters in the DMA_InitStruct.

Parameters
DMAy_Channelx,:where y can be 1 to select the DMA and x can be 1 to 5 for DMA1 to select the DMA Channel.
DMA_InitStruct,:pointer to a DMA_InitTypeDef structure that contains the configuration information for the specified DMA Channel.
Return values
None
void DMA_StructInit ( DMA_InitTypeDef *  DMA_InitStruct)

Fills each DMA_InitStruct member with its default value.

Parameters
DMA_InitStruct,:pointer to a DMA_InitTypeDef structure which will be initialized.
Return values
None
