pwr-hd44780

Documentation

A Rust crate allowing to communicate with the HD44780 LCDs.

What buses 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() { run().unwrap(); }

fn run() -> Result<(), Box> { // create the LCD's bus instance; // use device at address 0x27 on the first I2C bus let lcdbus = pwrhd44780::I2CBus::new( "/dev/i2c-1", 0x27, )?;

// create the direct LCD's instance;
// use bus created before and assume LCD's width x height = 20 x 4
let mut lcd = pwr_hd44780::DirectLcd::new(
    Box::new(lcd_bus),
    20, 4,
)?;

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

Ok(())

} ```
