Struct stm32_hal2::dma::Dma

pub struct Dma<D> {
    pub regs: D,
}

Represents a Direct Memory Access (DMA) peripheral.

Fields

regs: D

Implementations

impl<D> Dma<D> where
    D: Deref<Target = RegisterBlock>, 

pub fn new(regs: D) -> Self

Initialize a DMA peripheral, including enabling and resetting its RCC peripheral clock.

pub fn cfg_channel(
    &mut self,
    channel: DmaChannel,
    periph_addr: u32,
    mem_addr: u32,
    num_data: u16,
    direction: Direction,
    periph_size: DataSize,
    mem_size: DataSize,
    cfg: ChannelCfg
)

Configure a DMA channel. See L4 RM 0394, section 11.4.4. Sets the Transfer Complete interrupt.

pub fn stop(&mut self, channel: DmaChannel)

Stop DMA.

pub fn transfer_is_complete(&mut self, channel: DmaChannel) -> bool

pub fn channel_select(&mut self, input: DmaInput)

Select which peripheral on a given channel we’re using. See L44 RM, Table 41.

pub fn enable_interrupt(&mut self, channel: DmaChannel, interrupt: DmaInterrupt)

Enable a specific type of interrupt. Note that the TransferComplete interrupt is enabled automatically, by the cfg_channel method.

pub fn clear_interrupt(&mut self, channel: DmaChannel, interrupt: DmaInterrupt)
