pub struct DisplayController<T: 'static + SupportedWord> { /* fields omitted */ }

Implementations

impl<T: 'static + SupportedWord> DisplayController<T>

pub fn new(
    ltdc: LTDC,
    dma2d: DMA2D,
    pixel_format: PixelFormat,
    config: DisplayConfig,
    hse: Option<&HSEClock>
) -> DisplayController<T>

Create and configure the DisplayController

pub fn config_layer(
    &mut self,
    layer: Layer,
    buffer: &'static mut [T],
    pixel_format: PixelFormat
)

Configure the layer

Note : the choice is made (for the sake of simplicity) to make the layer as big as the screen

Color Keying and CLUT are not yet supported

pub fn enable_layer(&self, layer: Layer)

Enable the layer

pub fn draw_pixel(&mut self, layer: Layer, x: usize, y: usize, color: T)

Draw a pixel at position (x,y) on the given layer

pub unsafe fn draw_rectangle(
    &mut self,
    layer: Layer,
    top_left: (usize, usize),
    bottom_right: (usize, usize),
    color: u32
)

Draw hardware accelerated rectangle

Safety

TODO: use safer DMA transfers

pub fn reload(&self)

Reload display controller immediatly
