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 - -*****************************************************************************/ -#include <inttypes.h> -#include <avr/io.h> -#include <avr/pgmspace.h> -#include <util/delay.h> -#include "hd44780.h" -
