where
    I: Write,
    D: DelayMs<u8>,
{ /* private fields */ }

Implementations

impl<'a, I, D> Lcd<'a, I, D>

where I: Write, D: DelayMs<u8>,

pub fn new( i2c: &'a mut I, address: u8, delay: &'a mut D, ) -> Result<Self, <I as Write>::Error>

pub fn clear(&mut self) -> Result<(), <I as Write>::Error>

Clear the display. The LCD display driver requires a 2ms delay after clearing, which is why this method requires a delay object.

Errors

Returns a Result that will report I2C errors, if any.

pub fn home(&mut self) -> Result<(), <I as Write>::Error>

Home

Errors

Returns a Result that will report I2C errors, if any.

pub fn set_cursor_position( &mut self, col: u8, row: u8, ) -> Result<(), <I as Write>::Error>

Set the position of the cursor

Errors

Returns a Result that will report I2C errors, if any.

pub fn set_display( &mut self, display: Display, ) -> Result<(), <I as Write>::Error>

Control whether the display is on or off

Errors

Returns a Result that will report I2C errors, if any.

pub fn set_cursor(&mut self, cursor: Cursor) -> Result<(), <I as Write>::Error>

Sets the visiblity of the cursor, which is a non-blinking _

Errors

Returns a Result that will report I2C errors, if any.

pub fn set_blink(&mut self, blink: Blink) -> Result<(), <I as Write>::Error>

Turns on the blinking block cursor

Errors

Returns a Result that will report I2C errors, if any.

pub fn set_backlight( &mut self, backlight: Backlight, ) -> Result<(), <I as Write>::Error>

pub fn print(&mut self, s: &str) -> Result<(), <I as Write>::Error>

Adds a string to the current position. The cursor will advance after this call to the next column

Errors

Returns a Result that will report I2C errors, if any.
