LCD-Linux is a Linux software abstraction layer to drive LCD alphanumeric displays. It is freely inspired by the Linux tty layer and aims to be as much general and flexible as possible. Drivers for specific LCD controllers can be easily written.

Supported controllers: HD44780

HD44780 driver features:

Multi controller support.
8 and 4 bit mode support.
Used 4 bits can be specified at compile time.
I/O timings can be specified at compile time.
Supports all screen sizes up to the maximum of the HD44780 (80 characters per controller).
Supports user definable fonts.
Supports full read and write from the device to read the display state and set user definable characters.
Supports both available font sizes when the HD44780 is run in single line mode.

What's New in This Release:
This release features a virtual screen abstraction, allowing for larger screen sizes, independently of the real size of the LCD attached to the system running LCD-Linux.
The implementation takes care to always keep the cursor in the visible area of the LCD and to scroll whenever the cursor exits the visible screen area.
One possible application is to use a tiny display as a sytem console by defining a virtual screen size of 25 rows by 80 columns.
