Struct DisplayCanvas

pub struct DisplayCanvas<const L: usize, const W: usize> { /* private fields */ }

A display canvas for the Max 7219

W represents how many displays there are L represents how many layers there are

Layers are simply stacked on top of each other where if a pixel is set in any of the layers then the pixel illuminates, therefore no layer has “priority” over the other and the order of layers is irrelevant

Implementations

impl<const L: usize, const W: usize> DisplayCanvas<L, W>

pub fn new() -> Self

pub fn update_layer(&mut self, layer_index: usize, layer: CanvasLayer<W>)

pub fn as_raw_data(&self, display_index: usize) -> [u8; 8]

pub fn write_to_display<C: Connector>( &self, display_index: usize, display: &mut MAX7219<C>, )
