This is an integration of Peter Fleury's LCD library. This page will explain the basics. [For in depth documentation visit his page.](http://homepage.hispeed.ch/peterfleury/doxygen/avr-gcc-libraries/group__pfleury__lcd.html)
You can enable support for HD44780 Displays by setting the `HD44780_ENABLE` flag in your keyboards `rules.mk` to yes. This will use about 400 KB of extra space.

## Usage
## Usage
To initialize your display, call `lcd_init()` with one of these parameters:
````
LCD_DISP_OFF : display off
LCD_DISP_ON : display on, cursor off
LCD_DISP_ON_CURSOR : display on, cursor on
LCD_DISP_ON_CURSOR_BLINK : display on, cursor on flashing
LCD_DISP_ON_CURSOR_BLINK : display on, cursor on flashing
````
This is best done in your keyboards `matrix_init_kb` or your keymaps `matrix_init_user`.
It is advised to clear the display before use.
