uint32_t LL_BDMA_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 Transfer Direction

This feature can be modified afterwards using unitary function LL_BDMA_SetDataTransferDirection().

Definition at line 85 of file stm32h7xx_ll_bdma.h.

Referenced by LL_BDMA_Init(), and LL_BDMA_StructInit().

uint32_t LL_BDMA_InitTypeDef::MemoryOrM2MDstAddress

Specifies the memory base address for DMA transfer or as Destination base address in case of memory to memory transfer direction.

This parameter must be a value between Min_Data = 0 and Max_Data = 0xFFFFFFFF.

Definition at line 80 of file stm32h7xx_ll_bdma.h.

Referenced by LL_BDMA_Init(), and LL_BDMA_StructInit().

uint32_t LL_BDMA_InitTypeDef::MemoryOrM2MDstDataSize

Specifies the Memory data size alignment or Destination data size alignment (byte, half word, word) in case of memory to memory transfer direction. This parameter can be a value of Memory data alignment

This feature can be modified afterwards using unitary function LL_BDMA_SetMemorySize().

uint32_t LL_BDMA_InitTypeDef::MemoryOrM2MDstIncMode

Specifies whether the Memory address or Destination address in case of memory to memory transfer direction is incremented or not. This parameter can be a value of Memory increment mode

This feature can be modified afterwards using unitary function LL_BDMA_SetMemoryIncMode().

Definition at line 104 of file stm32h7xx_ll_bdma.h.

uint32_t LL_BDMA_InitTypeDef::Mode

Specifies the normal or circular operation mode. This parameter can be a value of Transfer mode

Note:

: The circular buffer mode cannot be used if the memory to memory data transfer direction is configured on the selected Channel

This feature can be modified afterwards using unitary function LL_BDMA_SetMode().

Referenced by LL_BDMA_Init(), and LL_BDMA_StructInit().

uint32_t LL_BDMA_InitTypeDef::NbData

Specifies the number of data to transfer, in data unit. The data unit is equal to the source buffer configuration set in PeripheralSize or MemorySize parameters depending in the transfer direction. This parameter must be a value between Min_Data = 0 and Max_Data = 0x0000FFFF

This feature can be modified afterwards using unitary function LL_BDMA_SetDataLength().

uint32_t LL_BDMA_InitTypeDef::PeriphOrM2MSrcAddress

Specifies the peripheral base address for BDMA transfer or as Source base address in case of memory to memory transfer direction.

This parameter must be a value between Min_Data = 0 and Max_Data = 0xFFFFFFFF.

uint32_t LL_BDMA_InitTypeDef::PeriphOrM2MSrcDataSize

Specifies the Peripheral data size alignment or Source data size alignment (byte, half word, word) in case of memory to memory transfer direction. This parameter can be a value of Peripheral data alignment

This feature can be modified afterwards using unitary function LL_BDMA_SetPeriphSize().

uint32_t LL_BDMA_InitTypeDef::PeriphRequest

Specifies the peripheral request. This parameter can be a value of DMAMUX2 Request selection

This feature can be modified afterwards using unitary function LL_BDMA_SetPeriphRequest().
