Enum DmaMode

pub enum DmaMode {
    Disabled,
    OneShot,
    Circular,
}

DMA mode

Note

The DMA transfer requests are blocked until the software clears the Event::Overrun event.

Variants

Disabled

DMA is disabled.

OneShot

In this mode, the ADC generates a DMA transfer request each time a new conversion data is available and stops generating DMA requests once the DMA has reached the last DMA transfer (when DMA end of transmission interrupt occurs) even if a conversion has been started again.

See Event::EndOfSequence

Circular

In this mode, the ADC generates a DMA transfer request each time a new conversion data is available in the data register, even if the DMA has reached the last DMA transfer. This allows configuring the DMA in circular mode to handle a continuous analog input data stream.

Trait Implementations

impl Clone for DmaMode

fn clone(&self) -> DmaMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DmaMode

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

Formats the value using the given formatter.

impl Default for DmaMode

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DmaMode

fn eq(&self, other: &DmaMode) -> 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.
