HAL_DMAEx_MultiBufferStart_IT
Function name
HAL_StatusTypeDef HAL_DMAEx_MultiBufferStart_IT
(DMA_HandleTypeDef * hdma, uint32_t SrcAddress, uint32_t
DstAddress, uint32_t SecondMemAddress, uint32_t
DataLength)
Function description
Starts the multi_buffer DMA Transfer with interrupt enabled.
Parameters
hdma: pointer to a DMA_HandleTypeDef structure that
contains the configuration information for the specified DMA
Stream.
SrcAddress: The source memory Buffer address
DstAddress: The destination memory Buffer address
SecondMemAddress: The second memory Buffer address
in case of multi buffer Transfer
DataLength: The length of data to be transferred from
source to destination
Return values
HAL: status
HAL_DMAEx_ChangeMemory
Function name
HAL_StatusTypeDef HAL_DMAEx_ChangeMemory
(DMA_HandleTypeDef * hdma, uint32_t Address,
HAL_DMA_MemoryTypeDef memory)
Function description
Change the memory0 or memory1 address on the fly.
Parameters
hdma: pointer to a DMA_HandleTypeDef structure that
contains the configuration information for the specified DMA
Stream.
Address: The new address
memory: the memory to be changed, This parameter can be
one of the following values: MEMORY0 / MEMORY1
Return values
HAL: status
Notes
The MEMORY0 address can be changed only when the
current transfer use MEMORY1 and the MEMORY1 address
can be changed only when the current transfer use
MEMORY0.
