# You should build a tiny Makefile for each of your projects and just declare a few
|
|
# things in it, then include this Makefile in it. Your Makefile should be in the same
|
|
# directory as your TARGET file (see below).
|
|
#
|
|
# Exemplia gratia:
|
|
#
|
|
# the name of your main file, with no extension
|
|
# TARGET = foo
|
|
# the C source files
|
|
# SRC = foo.c bar.c
|
|
# the C++ source files
|
|
# PSRC = baz.cpp qux.cpp
|
|
# extra Arduino libraries
|
|
# ARDLIBS = SoftwareSerial

|
# A number of necessary variables are set to defaults below, but you can override them
|
|
# in your own Makefile:
|
|
# F_CPU (default is 16000000)
|
|
# MCU (default is atmega328p)
|
|
# AVRDUDE_PORT (default is com8)
|
|
#
|
|
# To include Arduino libraries, define
|
|
# ARDLIBS = SoftwareSerial Servo...
|
|
#
|
|
# This Makefile requires that you have no spaces in your file paths, including
|
|
# your Arduino directory (where you core, variants, and libs are stored). If
|
|
# necessary, copy your Arduino source files to another directory and define that
|
|
# directory in the variables for this file.
|
|
|
|
# The following tasks are defined in this Makefile:
|
|
# make all = Make software and program
|
|
# make clean = Clean out built project files.
|
|
# make program = Download the hex file to the device, using avrdude.

# SRC = source files ending with .c
