DMA_InitTypeDef struct

Specifies the channel used for the specified stream. This parameter can be a value of DMA_Channel_selection.

Specifies if the data will be transferred from memory to peripheral, from memory to memory or from peripheral to memory. This parameter can be a value of DMA_Data_transfer_direction.

Specifies whether the Peripheral address register should be incremented or not. This parameter can be a value of DMA_Peripheral_incremented_mode.

Specifies whether the memory address register should be incremented or not. This parameter can be a value of DMA_Memory_incremented_mode.

Specifies the Peripheral data width. This parameter can be a value of DMA_Peripheral_data_size.

Specifies the Memory data width. This parameter can be a value of DMA_Memory_data_size.

Specifies the operation mode of the DMAy Streamx. This parameter can be a value of DMA_mode.

Specifies the software priority for the DMAy Streamx. This parameter can be a value of DMA_Priority_level.

Specifies if the FIFO mode or Direct mode will be used for the specified stream. This parameter can be a value of DMA_FIFO_direct_mode.

Specifies the FIFO threshold level. This parameter can be a value of DMA_FIFO_threshold_level.

Specifies the Burst transfer configuration for the memory transfers. It specifies the amount of data to be transferred in a single non interruptible transaction. This parameter can be a value of DMA_Memory_burst.

Specifies the Burst transfer configuration for the peripheral transfers. It specifies the amount of data to be transferred in a single non interruptible transaction. This parameter can be a value of DMA_Peripheral_burst.
