Struct stm32_hal2::dma::ChannelCfg

pub struct ChannelCfg {
    pub priority: Priority,
    pub circular: Circular,
    pub periph_incr: IncrMode,
    pub mem_incr: IncrMode,
}

This struct is used to pass common (non-peripheral and non-use-specific) data when configuring a channel.

Fields

priority: Priority

Channel priority compared to other channels; can be low, medium, high, or very high. Defaults to medium.

circular: Circular

Enable or disable circular DMA. If enabled, the transfer continues after reaching the end of the buffer, looping to the beginning. A TC interrupt first each time the end is reached, if set. Defaults to disabled.

periph_incr: IncrMode

Whether we increment the peripheral address on data word transfer; generally (and by default) disabled.

mem_incr: IncrMode

Whether we increment the buffer address on data word transfer; generally (and by default) enabled.

Trait Implementations

impl Clone for ChannelCfg

fn clone(&self) -> ChannelCfg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for ChannelCfg

fn default() -> Self

Returns the “default value” for a type.
