pwr-hd44780

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 interface instance; // use device at address 0x27 on the first i2c bus let mut lcdinterface = pwrhd44780::interface::I2C::new( "/dev/i2c-1", 0x27 );

// create the LCD's frontend;
// use interface created before and assume LCD's width x height = 20 x 4
let mut lcd = pwr_hd44780::frontend::Direct::new(
    &mut lcd_interface,
    20, 4
);

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

} ```
