Field Documentation

uint32_t MDMA_InitTypeDef::BufferTransferLength

Specifies the buffer Transfer Length (number of bytes), this is the number of bytes to be transferred in a single transfer (1 byte to 128 bytes)

Referenced by HAL_MDMA_Init(), HAL_MDMA_LinkedList_CreateNode(), and MDMA_Init().

uint32_t MDMA_InitTypeDef::DataAlignment

Specifies the source to destination Memory data packing/padding mode. This parameter can be a value of MDMA data alignment

Definition at line 77 of file stm32h7xx_hal_mdma.h.

Referenced by HAL_MDMA_Init(), and HAL_MDMA_LinkedList_CreateNode().

int32_t MDMA_InitTypeDef::DestBlockAddressOffset

this field specifies the Next block destination address offset signed value : if > 0 then increment the next block destination Address by offset from where the last block ends if < 0 then decrement the next block destination Address by offset from where the last block ends if == 0, the next block destination address starts from where the last block ends

Definition at line 106 of file stm32h7xx_hal_mdma.h.

Referenced by HAL_MDMA_Init(), HAL_MDMA_LinkedList_CreateNode(), and MDMA_Init().

uint32_t MDMA_InitTypeDef::DestBurst

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

Note:
: the burst may be FIXED/INCR based on DestinationInc value , the BURST must be programmed as to ensure that the burst size will be lower than than BufferTransferLength
