# Simple AVR Makefile
# by Henri Nurmi a.k.a. Henkru @ http://soundslikeaplan.net
#
# Use:
# PROJECT = Name of project. Example: LED_Blinker etc.
# SOURCES = List all sources. Example: main.c foo.c asd.c etc.
# MCU	  = Microcontroller. Example: atemga328p, attiny2313 etc. (avr-gcc)
# PARTNO  = AVR device for avrdude.
# PROGRAMMER = Programmer type. (avrdude)
# PORT	     = Connection port of programmer.
#
# "make all" compiling 
# "make load" upload program to device
#
