Structs§

  • Dma1
    Dma1 is kept as a separate type from Dma2 in order to allow for more compile-time checks.
  • Dma2
    For an explanation of why this is its own type, see the docs for the Dma1 struct.
  • DmaRegisters
    DMA controller
  • Msize
  • Psize
  • Stream
    This struct refers to a DMA Stream

Enums§

  • ChannelId
    Each stream can be selected among up to eight channel requests. This is basically STM32F446RE’s way of selecting the peripheral for the stream. Nevertheless, the use of the term channel here is confusing. Table 28 describes the mapping between stream, channel, and peripherals.
  • Direction
    DMA transfer direction. Section 9.5.5
  • Dma1Peripheral
    List of peripherals managed by DMA1
  • Dma2Peripheral
    List of peripherals managed by DMA2
  • FifoSize
    DMA transfer mode. Section 9.5.10
  • Size
    DMA data size. Section 9.5.5
  • StreamId
    The DMA stream number. What other microcontrollers refer to as “channel”, STM32F446RE refers to as “streams”. STM32F446RE has eight streams. A stream transfers data between memory and peripheral.
  • TransferMode
