Trait implemented by all DMA channels

Required methods

fn event_occurred(&self, event: Event) -> bool

Is the interrupt flag for the given event set?

fn clear_event(&mut self, event: Event)

Clear the interrupt flag for the given event.

Passing Event::Any clears all interrupt flags.

Note that the the global interrupt flag is not automatically cleared even when all other flags are cleared. The only way to clear it is to call this method with Event::Any.

Provided methods

fn reset(&mut self)

Reset the control registers of this channel. This stops any ongoing transfers.

fn set_peripheral_address(&mut self, address: u32, inc: Increment)

Set the base address of the peripheral data register from/to which the data will be read/written.

Only call this method on disabled channels.

Panics

Panics if this channel is enabled.

fn set_memory_address(&mut self, address: u32, inc: Increment)

Set the base address of the memory area from/to which the data will be read/written.

Only call this method on disabled channels.

Panics

Panics if this channel is enabled.

fn set_transfer_length(&mut self, len: u16)

Set the number of words to transfer.

Only call this method on disabled channels.

Panics

Panics if this channel is enabled.

fn set_word_size<W>(&mut self)

Set the word size.

Panics

Panics if the word size is not one of 8, 16, or 32 bits.

fn set_priority_level(&mut self, priority: Priority)

Set the priority level of this channel

fn set_direction(&mut self, direction: Direction)

Set the transfer direction

fn listen(&mut self, event: Event)

Enable the interrupt for the given event

fn unlisten(&mut self, event: Event)

Disable the interrupt for the given event

fn enable(&mut self)

Start a transfer

fn disable(&mut self)

Stop the current transfer

fn is_enabled(&self) -> bool

Is there a transfer in progress on this channel?
