Member Data Documentation

uint16_t DMA_InitTypeDef::DMA_BufferSize

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

Definition at line 62 of file stm32f30x_dma.h.

uint32_t DMA_InitTypeDef::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.

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

Definition at line 69 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_Channel

Specifies the channel used for the specified stream. This parameter can be a value of DMA_channel

Definition at line 56 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_DIR

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

Specifies if the peripheral is the source or destination. This parameter can be a value of DMA_data_transfer_direction

Definition at line 65 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_FIFOMode

Specifies if the FIFO mode or Direct mode will be used for the specified Stream. This parameter can be a value of DMA_fifo_direct_mode

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

Definition at line 93 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_FIFOThreshold

Specifies the FIFO threshold level. This parameter can be a value of DMA_fifo_threshold_level

Definition at line 98 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_M2M

Specifies if the DMAy Channelx will be used in memory-to-memory transfer. This parameter can be a value of DMA_memory_to_memory

Definition at line 83 of file stm32f10x_dma.h.

uint32_t DMA_InitTypeDef::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.

Definition at line 61 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_MemoryBaseAddr

Specifies the memory base address for DMAy Channelx.

Definition at line 54 of file stm32f10x_dma.h.

uint32_t DMA_InitTypeDef::DMA_MemoryBurst

Specifies the Burst transfer configuration for the memory transfers. It specifies the amount of data to be transferred in a single non interruptable transaction. This parameter can be a value of DMA_memory_burst

Note
The burst mode is possible only if the address Increment mode is enabled.

Definition at line 101 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_MemoryDataSize

Specifies the Memory data width. This parameter can be a value of DMA_memory_data_size

Definition at line 82 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_MemoryInc

Specifies whether the memory address register should be incremented or not. This parameter can be a value of DMA_memory_incremented_mode

Specifies whether the memory address register is incremented or not. This parameter can be a value of DMA_memory_incremented_mode

Definition at line 76 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_Mode

Specifies the operation mode of the DMAy Streamx. This parameter can be a value of DMA_circular_normal_mode

Note
The circular buffer mode cannot be used if the memory-to-memory data transfer is configured on the selected Stream

Specifies the operation mode of the DMAy Channelx. This parameter can be a value of DMA_circular_normal_mode.

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

Specifies the operation mode of the DMAy Channelx. This parameter can be a value of DMA_circular_normal_mode

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

Definition at line 85 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_PeripheralBaseAddr

Specifies the peripheral base address for DMAy Streamx.

Specifies the peripheral base address for DMAy Channelx.

Definition at line 59 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_PeripheralBurst

Specifies the Burst transfer configuration for the peripheral transfers. It specifies the amount of data to be transferred in a single non interruptable transaction. This parameter can be a value of DMA_peripheral_burst

Note
The burst mode is possible only if the address Increment mode is enabled.

Definition at line 106 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_PeripheralDataSize

Specifies the Peripheral data width. This parameter can be a value of DMA_peripheral_data_size

Definition at line 79 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_PeripheralInc

Specifies whether the Peripheral address register should be incremented or not. This parameter can be a value of DMA_peripheral_incremented_mode

Specifies whether the Peripheral address register is incremented or not. This parameter can be a value of DMA_peripheral_incremented_mode

Definition at line 73 of file stm32f4xx_dma.h.
