Struct I8080Transfer 

pub struct I8080Transfer<'d, BUF: DmaTxBuffer, Dm: DriverMode> { /* private fields */ }

Represents an ongoing (or potentially finished) transfer using the I8080 LCD interface

Implementations

impl<'d, BUF: DmaTxBuffer, Dm: DriverMode> I8080Transfer<'d, BUF, Dm>

pub fn is_done(&self) -> bool

Returns whether Self::wait will not block.

pub fn cancel(self) -> (I8080<'d, Dm>, BUF::Final)

Stops this transfer on the spot and returns the peripheral and buffer.

pub fn wait(self) -> (Result<(), DmaError>, I8080<'d, Dm>, BUF::Final)

Waits for the transfer to finish and returns the peripheral and buffer.

Also clears the transfer interrupt so it can be used in interrupt handlers to handle the interrupt.

impl<BUF: DmaTxBuffer> I8080Transfer<'_, BUF, Async>

pub async fn wait_for_done(&mut self)

Waits for Self::is_done to return true.

impl<BUF: DmaTxBuffer> I8080Transfer<'_, BUF, Blocking>

Interrupt management for an ongoing transfer.

The driver itself has been consumed by I8080::send, so these methods take &self and allow an interrupt handler to manage the interrupt sources through the transfer object.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

pub fn listen(&self, interrupts: impl Into<EnumSet<I8080Interrupt>>)

Listens for the given LCD interrupt sources.

pub fn unlisten(&self, interrupts: impl Into<EnumSet<I8080Interrupt>>)

Stops listening for the given LCD interrupt sources.

pub fn interrupts(&self) -> EnumSet<I8080Interrupt>

Returns the asserted LCD interrupt sources.

pub fn clear_interrupts(&self, interrupts: impl Into<EnumSet<I8080Interrupt>>)

Clears the given asserted LCD interrupt sources.

pub fn listen_dma(&self, interrupts: impl Into<EnumSet<DmaTxInterrupt>>)

Listens for the given DMA TX interrupt sources.

pub fn unlisten_dma(&self, interrupts: impl Into<EnumSet<DmaTxInterrupt>>)

Stops listening for the given DMA TX interrupt sources.

pub fn interrupts_dma(&self) -> EnumSet<DmaTxInterrupt>

Returns the asserted DMA TX interrupt sources.

pub fn clear_interrupts_dma( &self, interrupts: impl Into<EnumSet<DmaTxInterrupt>>, )

Clears the given asserted DMA TX interrupt sources.

Trait Implementations

impl<BUF: DmaTxBuffer, Dm: DriverMode> Deref for I8080Transfer<'_, BUF, Dm>

Available on crate feature unstable only.

type Target = <BUF as DmaTxBuffer>::View

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<BUF: DmaTxBuffer, Dm: DriverMode> DerefMut for I8080Transfer<'_, BUF, Dm>

Available on crate feature unstable only.

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<BUF: DmaTxBuffer, Dm: DriverMode> Drop for I8080Transfer<'_, BUF, Dm>

Available on crate feature unstable only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
