Field Documentation

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::MemDataAlignment

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

Definition at line 63 of file stm32f1xx_hal_dma.h.

uint32_t DMA_InitTypeDef::MemInc

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

uint32_t DMA_InitTypeDef::Mode

Specifies the operation mode of the DMAy Channelx. 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 Channel
