Struct st7032i::ST7032i

pub struct ST7032i<I2C, D> { /* fields omitted */ }

Driver for the ST7032i

Methods

impl<I2C, E, D> ST7032i<I2C, D> where
    I2C: Read<Error = E> + Write<Error = E> + WriteRead<Error = E>,
    D: DelayMs<u8>, 

pub fn new(i2c: I2C, delay: D, lines: u8) -> Self

Initialize the ST7032i driver.

pub fn init(&mut self) -> Result<(), E>

Initialize the display.

pub fn on(&mut self) -> Result<(), E>

Switch display on

pub fn off(&mut self) -> Result<(), E>

Switch display off

pub fn clear(&mut self) -> Result<(), E>

Clear all the display data by writing "20H" (space code) to all DDRAM address, and set DDRAM address to "00H" into AC (address counter).

pub fn home(&mut self) -> Result<(), E>

Set DDRAM address to "0" and return cursor to its original position if shifted. The contents of DDRAM are not changed.

pub fn move_cursor(&mut self, row: u8, col: u8) -> Result<(), E>

Move cursor to specified location

pub fn show_cursor(&mut self, blink: bool) -> Result<(), E>

Show cursor

pub fn hide_cursor(&mut self) -> Result<(), E>

Hide cursor

pub fn enable_scroll(&mut self, entry: Direction) -> Result<(), E>

Enable autoscroll

pub fn disable_scroll(&mut self) -> Result<(), E>

Disable autoscroll

pub fn shift_display(&mut self, dir: Direction) -> Result<(), E>

Shift display to specified direction

pub fn shift_cursor(&mut self, dir: Direction) -> Result<(), E>

Shift cursor to specified direction

pub fn create_char(&mut self, offset: u8, bitmap: [u8; 8]) -> Result<(), E>

Create custom character in CGRAM
