Field Documentation

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 50 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_PeripheralBaseAddr

Specifies the peripheral base address for DMAy Streamx.

Definition at line 53 of file stm32f4xx_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 55 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

Definition at line 59 of file stm32f4xx_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.

Definition at line 63 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

Definition at line 67 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

Definition at line 70 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 73 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 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

Definition at line 79 of file stm32f4xx_dma.h.

uint32_t DMA_InitTypeDef::DMA_Priority

Specifies the software priority for the DMAy Streamx. This parameter can be a value of DMA_priority_level

Definition at line 84 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 87 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 92 of file stm32f4xx_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 95 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 100 of file stm32f4xx_dma.h.
