Trait Implementations

impl Hd44780 for Buffered

fn clear(&mut self) -> UnitResult

Clears the screen and moves cursor at (0, 0).

fn home(&mut self) -> UnitResult

Moves the cursor at (0, 0).

fn move_at(&mut self, y: usize, x: usize) -> UnitResult

Moves the cursor at given position.

fn print_char(&mut self, ch: u8) -> UnitResult

Prints a single ASCII character at current cursor's position and moves the cursor. Can be used to print custom-made characters (ie. the ones created by create_char).

fn set_backlight(&mut self, enabled: bool) -> UnitResult

Enables / disables the backlight.

fn set_cursor_blinking(&mut self, enabled: bool) -> UnitResult

Enables / disables blinking the cursor. Blinking means that the whole character box is blinking (a whole 5x8 or 5x10 box),

fn set_cursor_visible(&mut self, enabled: bool) -> UnitResult

Enables / disables the cursor. Visible means that only bottom of the character box is blinking (a single line).

fn set_text_visible(&mut self, enabled: bool) -> UnitResult

Shows / hides the text.

fn create_char(&mut self, idx: u8, lines: [u8; 8]) -> UnitResult

Creates a custom character from given bitmap.

fn height(&self) -> usize

Returns screen's height (number of lines).

fn width(&self) -> usize

Returns screen's width (number of characters per line).

fn print_char_at(&mut self, y: usize, x: usize, ch: u8) -> UnitResult

Prints a single ASCII character at given position and moves the cursor. Can be used to print custom-made characters (ie. the ones created by create_char).

fn print<T: Into<String>>(&mut self, str: T) -> UnitResult

Prints a string at current cursor's position and moves the cursor.

fn print_at<T: Into<String>>(
    &mut self,
    y: usize,
    x: usize,
    str: T
) -> UnitResult

Prints a string at given position.
