- Title: HD44780U LCD library
- Author: Peter Fleury <pfleury@gmx.ch> http://tinyurl.com/peterfleury
- License: GNU General Public License Version 3
- File: $Id: lcd.c,v 1.15.2.2 2015/01/17 12:16:05 peter Exp $
- Software: AVR-GCC 3.3
- Target: any AVR device, memory mapped mode only for AT90S4414/8515/Mega
-
- DESCRIPTION
- Basic routines for interfacing a HD44780U-based text lcd display
-
- Originally based on Volker Oth's lcd library,
- changed lcd_init(), added additional constants for lcd_command(),
- added 4-bit I/O mode, improved and optimized code.
-
- Library can be operated in memory mapped mode (LCD_IO_MODE=0) or in
- 4-bit IO port mode (LCD_IO_MODE=1). 8-bit IO port mode not supported.
-
- Memory mapped mode compatible with Kanda STK200, but supports also
- generation of R/W signal through A8 address line.
-
- USAGE
- See the C include lcd.h file for a description of each function

- @brief Basic routines for interfacing a HD44780U-based character LCD display
-
- LCD character displays can be found in many devices, like espresso machines, laser printers.
- The Hitachi HD44780 controller and its compatible controllers like Samsung KS0066U have become an industry standard for these types of displays.
-
- This library allows easy interfacing with a HD44780 compatible display and can be
- operated in memory mapped mode (LCD_IO_MODE defined as 0 in the include file lcd.h.) or in
- 4-bit IO port mode (LCD_IO_MODE defined as 1). 8-bit IO port mode is not supported.
-
- Memory mapped mode is compatible with old Kanda STK200 starter kit, but also supports
- generation of R/W signal through A8 address line.
-
- @see The chapter <a href=" http://homepage.hispeed.ch/peterfleury/avr-lcd44780.html" target="_blank">Interfacing a HD44780 Based LCD to an AVR</a>
- on my home page, which shows example circuits how to connect an LCD to an AVR controller.
