![polymer-char-lcd](https://jazz-soft.github.io/img/polymer-char-lcd.gif)

## Usage

### Install the Web Component

`npm install polymer-char-lcd --save`

### HTML

```html

  import 'polymer-char-lcd';

```

```html

```

## Attributes

`rom` - `jp` (default) for Japanese standard font or `eu` for European standard font;  

`rows` - number or rows; default: 2;  

`cols` - number of columns; default: 16;

## API

`char(r, c, h)` - set character `h` at row `r`, column `c`;  

`text(r, c, s)` - write string `s` starting at row `r`, column `c`;  

this function treats `\n` as new line and maps UNICODE characters to the internal character set;  

`font(n, data)` - define the pixels of the `n`-th character; `data` is an array of bytes.

## Testing with Polymer

Make sure the Polymer CLI is installed:

`npm install -g polymer-cli`  

In the project directory:  

run `npm install`  

run `polymer serve --open`

## Non-Polymer version
