Member Data Documentation

DMA_BufferSize

uint32_t DMA_InitType::DMA_BufferSize

Specifies the buffer size, in data unit, of the specified Stream. The data unit is equal to the configuration set in DMA_PeripheralDataSize or DMA_MemoryDataSize members depending in the transfer direction.

DMA_FIFO_flags

uint32_t DMA_InitType::DMA_FIFO_flags

Specifies if the FIFO mode or Direct mode will be used for the specified Stream, and FIFO threshold level. This parameter can be a value of DMA_fifo_direct_mode ORed DMA_fifo_threshold_level

Note

The Direct mode (FIFO mode disabled) cannot be used if the memory-to-memory data transfer is configured on the selected Stream

DMA_Memory0BaseAddr

uint32_t DMA_InitType::DMA_Memory0BaseAddr

Specifies the memory 0 base address for DMAy Streamx. This memory is the default memory used when double buffer mode is not enabled.

DMA_PeripheralBaseAddr

uint32_t DMA_InitType::DMA_PeripheralBaseAddr
