Member Data Documentation

◆ Direction

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

Definition at line 53 of file stm32h7xx_hal_dma.h.

◆ FIFOMode

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.

◆ FIFOThreshold

uint32_t DMA_InitTypeDef::FIFOThreshold

Specifies the FIFO threshold level.

This parameter can be a value of DMA FIFO threshold level

Definition at line 82 of file stm32h7xx_hal_dma.h.

◆ MemBurst

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.

Definition at line 85 of file stm32h7xx_hal_dma.h.

◆ MemDataAlignment

uint32_t DMA_InitTypeDef::MemDataAlignment

Specifies the Memory data width.

This parameter can be a value of DMA Memory data size

Definition at line 66 of file stm32h7xx_hal_dma.h.

◆ MemInc

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.

◆ Mode

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

Definition at line 69 of file stm32h7xx_hal_dma.h.

◆ PeriphBurst

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.

Definition at line 91 of file stm32h7xx_hal_dma.h.

◆ PeriphDataAlignment

uint32_t DMA_InitTypeDef::PeriphDataAlignment

Specifies the Peripheral data width.

This parameter can be a value of DMA Peripheral data size

Definition at line 63 of file stm32h7xx_hal_dma.h.

◆ PeriphInc

uint32_t DMA_InitTypeDef::PeriphInc

Specifies whether the Peripheral address register should be incremented or not.

This parameter can be a value of DMA Peripheral incremented mode

Definition at line 57 of file stm32h7xx_hal_dma.h.

◆ Priority

uint32_t DMA_InitTypeDef::Priority

Specifies the software priority for the DMAy Streamx.

This parameter can be a value of DMA Priority level

Definition at line 74 of file stm32h7xx_hal_dma.h.

◆ Request

uint32_t DMA_InitTypeDef::Request

Specifies the request selected for the specified stream.

This parameter can be a value of DMA Request selection

Definition at line 50 of file stm32h7xx_hal_dma.h.
