Field Documentation
uint32_t DMA_InitTypeDef::Channel
Specifies the channel used for the specified stream. This parameter can be a value of
DMA_Channel_selection
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
uint32_t DMA_InitTypeDef::PeriphInc
Specifies whether the Peripheral address register should be incremented or not. This
parameter can be a value of
uint32_t DMA_InitTypeDef::MemInc
Specifies whether the memory address register should be incremented or not. This
parameter can be a value of
uint32_t DMA_InitTypeDef::PeriphDataAlignment
Specifies the Peripheral data width. This parameter can be a value of
DMA_Peripheral_data_size
uint32_t DMA_InitTypeDef::MemDataAlignment
Specifies the Memory data width. This parameter can be a value of
DMA_Memory_data_size
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
uint32_t DMA_InitTypeDef::Priority
Specifies the software priority for the DMAy Streamx. This parameter can be a value
of DMA_Priority_level
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
190/1371
DMA_Peripheral_incremented_mode
DMA_Memory_incremented_mode
DMA_FIFO_direct_mode
