# Arduino Makefile
|
||||
# Arduino adaptation by mellis, eighthave, oli.keller
|
||||
# Modified by Kerry Wong to support NetBeans
|
||||
# Modified by Rob Gray (Graynomad) for use with Windows and no IDE
|
||||
# This works in my environment and I use it to program two different
|
||||
# 328-based boards and a Mega2560. It's not necessarily robust and
|
||||
# I may have broken something in the original file that I don't use.
|
||||
#
|
||||
# This makefile allows you to build sketches from the command line
|
||||
# without the Arduino environment.
|
||||
#
|
||||
# Instructions for using the makefile:
|
||||
#
|
||||
# 1. Copy this file into the folder with your sketch. The project code file
|
||||
# should have a .c extension however the file gets copied to a .cpp before
|
||||
# compilation so you still write in C++.
|
||||
#
|
||||
# 2. Modify the lines between the double ### rows to set the paths
|
||||
# comm ports etc for your system. EG. c:/progra~1/arduino/arduino-00
|
||||
# for the Arduino IDE, Note the use of short folder name, don't use
|
||||
# "Program files" because spaces will break the build.
|
||||
#
|
||||
# Set the line containing "MCU" to match your board's processor.
|
||||
# Typically ATmega328 or ATmega2560. If you're using a LilyPad Arduino,
|
||||
# change F_CPU to 8000000.
|
||||
#
|
||||
# 3. At the command line, change to the directory containing your
|
||||
# program's file and the makefile.
|
||||
#
|
||||
# 4. Type "make" and press enter to compile/verify your program.
|
||||
# The default make target will also perform the uplode using avrdude.
|
||||
#
|
||||
# The first time this is done all required libraries will be built
|
||||
# and a core.a file will be created in the output folder.
|
||||
#
|
||||
# NOTES:
|
||||
# All output goes into a folder called "output" underneath the working folder.
|
||||
# The default all: target creates symbol (.sym) and expanded assembly
|
||||
# (.lss) files and uploads the program.
