#ifndef LCDCONF_H
#define LCDCONF_H
// Define type of interface used to access the LCD
// LCD_MEMORY_INTERFACE:
// To use this mode you must supply the necessary hardware to connect the
// LCD to the CPU's memory bus. The CONTROL and DATA registers of the LCD
// (HD44780 chip) must appear in the CPU's memory map. This mode is faster
// than the port interface but requires a little extra hardware to make it
// work. It is especially useful when your CPU is already configured to
// use an external memory bus for other purposes (like accessing memory).
//
// LCD_PORT_INTERFACE:
// This mode allows you to connect the control and data lines of the LCD
// directly to the I/O port pins (no interfacing hardware is needed),
// but it generally runs slower than the LCD_MEMORY_INTERFACE.
// Depending on your needs, when using the LCD_PORT_INTERFACE, the LCD may
// be accessed in 8-bit or 4-bit mode. In 8-bit mode, one whole I/O port
// (pins 0-7) is required for the LCD data lines, but transfers are faster.
// In 4-bit mode, only I/O port pins 4-7 are needed for data lines, but LCD
// access is slower. In either mode, three additional port pins are
// required for the LCD interface control lines (RS, R/W, and E).
// Enable one of the following interfaces to your LCD
//#define LCD_MEMORY_INTERFACE
#define LCD_PORT_INTERFACE
// Enter the parameters for your chosen interface'

#ifndef LCD_DATA_ADDR
// CPU memory address of the LCD data register

// LCD delay
// This delay affects how quickly accesses are made to the LCD controller.
// The HD44780 LCD controller requires an access time of at least 1us.
// LCD_DELAY should be scaled to take at least half that time (500us).
// Each NOP takes 1 CPU clock cycle to execute. Thus, at 4MHz, you should
// use at least 2 NOPs, at 8MHz at least 4 NOPs, etc.
// You can also use the delay_us(xx) command for longer access times.
// LCD_DELAY is now automatically set in lcd.h,
// however, if you define it here, this definition will override the automatic setting
// use this for a fail-safe delay

# Makefile for AVR function library development and examples
# Author: Pascal Stang
#
# For those who have never heard of makefiles: a makefile is essentially a
# script for compiling your code. Most C/C++ compilers in the world are
# command line programs and this is even true of programming environments
# which appear to be windows-based (like Microsoft Visual C++). Although
# you could use AVR-GCC directly from the command line and try to remember
# the compiler options each time, using a makefile keeps you free of this
# tedious task and automates the process.
#
# For those just starting with AVR-GCC and not used to using makefiles,
# I've added some extra comments above several of the makefile fields which
# you will have to deal with.

###### dependecies, add any dependencies you need here ###################
# Dependencies tell the compiler which files in your code depend on which
# other files. When you change a piece of code, the dependencies allow
# the compiler to intelligently figure out which files are affected and
# need to be recompiled. You should only list the dependencies of *.o
# files. For example: uart.o is the compiled output of uart.c and uart.h
# and therefore, uart.o "depends" on uart.c and uart.h. But the code in
# uart.c also uses information from global.h, so that file should be listed
# in the dependecies too. That way, if you alter global.h, uart.o will be
# recompiled to take into account the changes.
