### MARKHAM'S NOTES:
|
||||
|
||||
# This Makefile includes the Arduino core sources. (Set ARDDIR here:)
|
||||
ARDDIR = /home/mrh/Downloads/arduino-1.8.8-linux64/arduino-1.8.8/
|
||||
#ARDDIR = /home/mrh/Downloads/arduino-1.8.8-linux64/arduino-1.8.8/hardware/arduino/avr
|
||||
|
||||
# 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:
|
||||
#
|
||||
# TARGET = foo # the name of your main file, with no extension
|
||||
# SRC = foo.c bar.c # the C source files
|
||||
# PSRC = baz.cpp qux.cpp # the C++ source files
|
||||
# ARDLIBS = SoftwareSerial # extra Arduino libraries
|
||||
# include /d/dev/avr/Makefile.base # this line includes the Makefile.base
|
||||
|
||||
# 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.
|
||||
|
||||
# This Makefile is modified from
|
||||
# WinAVR Sample makefile written by Eric B. Weddington, Jörg Wunsch, et al.
|
||||
# Modified (bringing often-changed options to the top) by Elliot Williams
|
||||
|
||||
# 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.
|
||||
|
||||
# Supply the following variables:
|
||||
# SRC = source files ending with .c
|
||||
# PSRC = source files ending with .cpp
