DMA2D Peripheral

Implementations

impl<'d, T: Instance> Dma2d<'d, T>

pub fn new(_peri: Peri<'d, T>) -> Self

Create a Dma2d peripheral

pub fn set_buffer(&mut self, kind: BufferKind, buffer: Buffer2D)

Configure a Buffer2D

pub fn set_region(&mut self, kind: BufferKind, region: &Region2D)

Configure a Region2D

pub fn set_color_config(&mut self, kind: BufferKind, config: &ColorConfig)

Set the color configuration for a buffer

pub async fn fill(&mut self, dest: &Region2D, color: u32) -> Result<(), Error>

Fill the output buffer with a color into an output region

pub async fn blit( &mut self, fg: &Region2D, dest: &Region2D, fg_color: Option<u32>, bg_color: Option<u32>, ) -> Result<(), Error>

Blit a source to a destination region using a fixed background color and alpha blending.

Pixel format conversion is applied to convert between input and output buffer color configurations which must be set before calling blit using Dma2d::set_color_config on both [BufferKind::Foreground'] and [BufferKind::Output`]

If the input buffer is A8, a fixed color may be provided in fg_color which will set the foreground RGB channels from the FGCOLR register.

If None is provided as bg_color, the background defaults to black.
