These files contain the LCD module drive, Basic routines for interfacing a text lcd display with any AVR device

DATE CREATED:

• 18/1/2015

Software:

• AVR-GCC 3.4.1057, Atmel Studio 6 (Version: 6.2.1153)

Target:

• Any AVR device

DESCRIPTION:

• Originally based on Peter Fleury's lcd library,
• Changed/Added: configure each pin from data and control pins as individual (Define Any Port and Any Pin number),
• Added: improved and optimized code.

Options:

• Library can be operated in 4-bit IO port mode or 8-bit IO port mode, depending on the value of LCD_IO_MODE in lcd.h
• You can connect the data/control bins at any port and any pin number, each from its individual define

Files: NOTE: _You have to download all these files and just include the lcd.h to your project _
