# LCD LM1602 I2C driver

Driver to write characters to LCD displays with a LM1602 connected via i2c like [this one] with
16x2 characters. It requires a I2C instance implementing [`embedded_hal::blocking::i2c::Write`]
and a instance to delay execution with [`embedded_hal::blocking::delay::DelayMs`].

Usage:
```
const LCD_ADDRESS: u8 = 0x27; // Address depends on hardware, see link below

// Create a I2C instance, needs to implement embedded_hal::blocking::i2c::Write, this
// particular uses the arduino_hal crate for avr microcontrollers like the arduinos.
let dp = arduino_hal::Peripherals::take().unwrap();
let pins = arduino_hal::pins!(dp);
let mut i2c = arduino_hal::I2c::new(
    dp.TWI, //
    pins.a4.into_pull_up_input(), // use respective pins
    pins.a5.into_pull_up_input(),
    50000,
);
let mut delay = arduino_hal::Delay::new();

let mut lcd = lcd_lcm1602_i2c::Lcd::new(&mut i2c, &mut delay)
    .address(LCD_ADDRESS)
    .cursor_on(false) // no visible cursos
    .rows(2) // two rows
    .init().unwrap();
```

This [site][lcd address] describes how to find the address of your LCD devices.

There is a similar crate [lcd_1602_i2c] but that did not work with [this display][this one].
