Struct Display 

pub struct Display<P, U>
where
    U: Into<Address> + Home,
{ /* private fields */ }

A HD44780 compliant display.

It provides a high-level and hardware agnostic interface to controll a HD44780 compliant liquid crystal display (LCD).

Implementations

impl<P, U> Display<P, U>

where P: Init + Send + Receive, U: Into<Address> + Home,

pub fn new(connection: P) -> Self

Create a new Display using the given connection.

pub fn init(&self, builder: &FunctionSetBuilder)

pub fn set_entry_mode(&self, builder: &EntryModeBuilder)

Sets the entry mode of the display.

pub fn set_display_control(&self, builder: &DisplayControlBuilder)

Sets the display control settings.

pub fn shift_cursor(&mut self, direction: ShiftTo)

Shifts the cursor to the left or the right by the given offset.

Note: Consider to use seek() for longer distances.

pub fn shift(&self, direction: ShiftTo)

Shifts the display to the right or the left by the given offset.

Note that the first and second line will shift at the same time.

When the displayed data is shifted repeatedly each line moves only horizontally. The second line display does not shift into the first line position.

pub fn clear(&self)

Clears the entire display, sets the cursor to the home position and undo all display shifts.

It also sets the cursor’s move direction to Increment.

pub fn seek(&mut self, pos: SeekFrom<U>)

Seeks to an offset in display data RAM.

pub fn seek_cgram(&mut self, pos: SeekFrom<U>)

Seeks to an offset in display character generator RAM.

pub fn write(&mut self, c: u8)

Writes the given byte to data or character generator RAM, depending on the previous seek operation.

pub fn read_byte(&mut self) -> u8

Reads a single byte from data RAM.

pub fn read_busy_flag(&self) -> (bool, u8)

Reads busy flag and the cursor’s current address.

pub fn write_message(&mut self, msg: &str)

Writes the given message to data or character generator RAM, depending on the previous seek operation.

pub fn get_connection(self) -> P
