◆ DMA_InitTypeDef

struct DMA_InitTypeDef

DMA Configuration Structure definition.

Definition at line 48 of file stm32f4xx_hal_dma.h.

Data Fields
uint32_t	Channel	Specifies the channel used for the specified stream. This parameter can be a value of DMA Channel selection
uint32_t	Direction	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
uint32_t	FIFOMode	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 Note The Direct mode (FIFO mode disabled) cannot be used if the memory-to-memory data transfer is configured on the selected stream
uint32_t	FIFOThreshold	Specifies the FIFO threshold level. This parameter can be a value of DMA FIFO threshold level
uint32_t	MemBurst	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 Note The burst mode is possible only if the address Increment mode is enabled.
uint32_t	MemDataAlignment	Specifies the Memory data width. This parameter can be a value of DMA Memory data size
uint32_t	MemInc	Specifies whether the memory address register should be incremented or not. This parameter can be a value of DMA Memory incremented mode
uint32_t	Mode	Specifies the operation mode of the DMAy Streamx. This parameter can be a value of DMA mode Note The circular buffer mode cannot be used if the memory-to-memory data transfer is configured on the selected Stream
uint32_t	PeriphBurst	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 Note The burst mode is possible only if the address Increment mode is enabled.
uint32_t	PeriphDataAlignment	Specifies the Peripheral data width. This parameter can be a value of DMA Peripheral data size
uint32_t	PeriphInc	Specifies whether the Peripheral address register should be incremented or not. This parameter can be a value of DMA Peripheral incremented mode
uint32_t	Priority	Specifies the software priority for the DMAy Streamx. This parameter can be a value of DMA Priority level
