Struct LinearItem 

#[repr(C)]
pub struct LinearItem {
    pub item: Item,
    pub llr: ChLlr,
}

A linked-list item for linear GPDMA transfers.

Also works for 2D-capable GPDMA channels, but does not use 2D capabilities.

Fields

item: Item

Common item fields (TR1, TR2, BR1, SAR, DAR).

llr: ChLlr

Linked-list address register.

Trait Implementations

impl Clone for LinearItem

fn clone(&self) -> LinearItem

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinearItem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LinearItem

fn default() -> LinearItem

Returns the “default value” for a type.

impl Format for LinearItem

where Item: Format, ChLlr: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl LinkedListItem for LinearItem

const IS_2D: bool = false

Whether this item type requires a 2D-capable channel.

type Config = ItemConfig

Per-item configuration passed at construction time.

unsafe fn new_read<MW: Word, PW: Word>( request: Request, peri_addr: *mut PW, buf: &mut [MW], config: Self::Config, ) -> Self

Create a new read DMA transfer item (peripheral to memory).

unsafe fn new_write<MW: Word, PW: Word>( request: Request, buf: &[MW], peri_addr: *mut PW, config: Self::Config, ) -> Self

Create a new write DMA transfer item (memory to peripheral).

fn link_to(&mut self, next: u16)

Link to the next item at the given offset address.

fn unlink(&mut self)

Unlink the next item (disables channel update bits).

fn transfer_count(&self) -> usize

The item’s transfer count in number of destination words.
