Implementations§

Source§

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

Source

pub fn new(regs: D) -> Self

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

Source

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

Configure a DMA channel. See L4 RM 0394, section 11.4.4. Sets the Transfer Complete interrupt. Note that this fn has been (perhaps) depreciated by the standalone fn.

Source

pub fn stop(&mut self, channel: DmaChannel) -> Result<()>

Stop a DMA transfer, if in progress.

Source

pub fn clear_interrupt( &mut self, channel: DmaChannel, interrupt: DmaInterrupt, ) -> Result<()>

Clear an interrupt flag.

Source

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

Source

pub fn enable_interrupt( &mut self, channel: DmaChannel, interrupt: DmaInterrupt, ) -> Result<()>

Enable a specific type of interrupt.

Source

pub fn disable_interrupt( &mut self, channel: DmaChannel, interrupt: DmaInterrupt, ) -> Result<()>

Disable a specific type of interrupt. todo: Non-H7 version too!

Methods from Deref<Target = RegisterBlock>§

Source

pub fn isr(&self) -> &Reg<ISRrs>

0x00 - interrupt status register

Source

pub fn ifcr(&self) -> &Reg<IFCRrs>

0x04 - DMA interrupt flag clear register

Source

pub fn ch(&self, n: usize) -> &CH

0x08..0xa8 - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

`n` is the index of cluster in the array. `n == 0` corresponds to `CH1` cluster.
Source

pub fn ch_iter(&self) -> impl Iterator<Item = &CH>

Iterator for array of: 0x08..0xa8 - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

Source

pub fn ch1(&self) -> &CH

0x08..0x1c - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

Source

pub fn ch2(&self) -> &CH

0x1c..0x30 - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

Source

pub fn ch3(&self) -> &CH
