uint32_t DMA_InitTypeDef::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 DMA_InitTypeDef::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

Definition at line 77 of file stm32h7xx_hal_dma.h.

uint32_t DMA_InitTypeDef::FIFOThreshold

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

uint32_t DMA_InitTypeDef::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 DMA_InitTypeDef::MemDataAlignment

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

uint32_t DMA_InitTypeDef::MemInc

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

Definition at line 60 of file stm32h7xx_hal_dma.h.

Referenced by HAL_DMA_Init().

uint32_t DMA_InitTypeDef::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 DMA_InitTypeDef::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.
