Struct BurstConfig

pub struct BurstConfig {
    pub external_memory: ExternalBurstConfig,
    pub internal_memory: InternalBurstConfig,
}

Available on crate feature unstable only.

Burst transfer configuration.

Fields

external_memory: ExternalBurstConfig

Configures the burst size for PSRAM transfers.

Burst mode is always enabled for PSRAM transfers.

internal_memory: InternalBurstConfig

Enables or disables the burst mode for internal memory transfers.

The burst size is not configurable.

Implementations

impl BurstConfig

pub const DEFAULT: Self

The default burst mode configuration.

impl BurstConfig

pub const fn min_compatible_alignment(self) -> usize

Calculates an alignment that is compatible with the current burst configuration.

This is an over-estimation so that Descriptors can be safely used with any DMA channel in any direction.

pub const fn max_compatible_chunk_size(self) -> usize

Calculates a chunk size that is compatible with the current burst configuration’s alignment requirements.

This is an over-estimation so that Descriptors can be safely used with any DMA channel in any direction.

Trait Implementations

impl Clone for BurstConfig

fn clone(&self) -> BurstConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BurstConfig

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

Formats the value using the given formatter.

impl Default for BurstConfig

fn default() -> Self

Returns the “default value” for a type.

impl From<ExternalBurstConfig> for BurstConfig

fn from(external_memory: ExternalBurstConfig) -> Self

Converts to this type from the input type.

impl From<InternalBurstConfig> for BurstConfig

fn from(internal_memory: InternalBurstConfig) -> Self

Converts to this type from the input type.

impl PartialEq for BurstConfig

fn eq(&self, other: &BurstConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
