Struct unicorn_hat_hd_2::UnicornHatHd

pub struct UnicornHatHd { /* private fields */ }

Provide high-level access to the Unicorn HAT HD.

Implementations

impl UnicornHatHd

pub fn new(bus: Bus, slave_select: SlaveSelect) -> Result<UnicornHatHd, Error>

Create a new UnicornHatHd with the provided Bus and SlaveSelect

pub fn display(&mut self) -> Result<(), Error>

Write the display buffer to the Unicorn HAT HD.

pub fn set_pixel(&mut self, x_coord: usize, y_coord: usize, c: RGB8)

Set an individual pixel’s RGB value.

The origin ((0, 0)) is the top-left of the display, with x & y increasing to the right, and down, respectively.

pub fn get_pixel(&self, x_coord: usize, y_coord: usize) -> RGB8

Return a tuple of an individual pixel’s RGB value.

The origin ((0, 0)) is the top-left of the display, with x & y increasing to the right, and down, respectively.

NOTE: This returns what’s in the display buffer, not what the physical pixel is set to.

pub fn clear_pixels(&mut self)

Clear the internal buffer of pixel states.

To clear the display itself, you’ll still need to call display to update the Unicorn HAT HD.

impl Default for UnicornHatHd

fn default() -> UnicornHatHd

Create a UnicornHatHd using the default Bus::Spi0 and SlaveSelect::Ss0.

This will panic if initialization fails.
