pwr-hd44780

Documentation

A Rust crate allowing to communicate with the HD44780 LCDs.

What interfaces are supported?

4-bit GPIO bus (thanks to the rppal library),
I2C bus (thanks to the rust-i2cdev library).

Would you mind showing me some code?

Sure, pal:

```rust extern crate pwr_hd44780;

use pwr_hd44780::Hd44780;

fn main() { // create the LCD's interface let mut lcdinterface = pwrhd44780::interface::I2C::new("/dev/i2c-1", 0x27);

// create the LCD's frontend
let mut lcd = pwr_hd44780::frontend::Direct::new(
    &mut lcd_interface,

    pwr_hd44780::Properties {
        width: 16,
        height: 2,
        font: pwr_hd44780::Font::Font5x8,
    }
);

// finally - print our text
lcd.clear();
lcd.print(String::from("Hello World! :-)"));

} ```
