# Arduino makefile
|
|
#
|
|
# This makefile allows you to build sketches from the command line
|
|
# without the Arduino environment (or Java).
|
|
#
|
|
# The Arduino environment does preliminary processing on a sketch before
|
|
# compiling it. If you're using this makefile instead, you'll need to do
|
|
# a few things differently:
|
|
#
|
|
# - Give your program's file a .cpp extension (e.g. foo.cpp).
|
|
#
|
|
# - Put this line at top of your code: #include <WProgram.h>
|
|
#
|
|
# - Write prototypes for all your functions (or define them before you
|
|
# call them). A prototype declares the types of parameters a
|
|
# function will take and what type of value it will return. This
|
|
# means that you can have a call to a function before the definition
|
|
# of the function. A function prototype looks like the first line of
|
|
# the function, with a semi-colon at the end. For example:
|
|
# int digitalRead(int pin);
|
|
#
|
|
# - Write a main() function for your program that returns an int, calls
|
|
# init() and setup() once (in that order), and then calls loop()
|
|
# repeatedly():
|
|
#
|
|
# int main()
|
|
# {
|
|
# init();
|
|
# setup();
|
|
#
|
|
# for (;;)
|
|
# loop();
|
|
#
|
|
# return 0;
|
|
# }
|
|
#
|
|
# Instructions for using the makefile:
|
|
#
|
|
# 1. Copy this file into the folder with your sketch.
|
|
#
|
|
# 2. Below, modify the line containing "TARGET" to refer to the name of
|
|
# of your program's file without an extension (e.g. TARGET = foo).
|
|
#
|
|
# 3. Modify the line containg "ARDUINO" to point the directory that
|
|
# contains the Arduino core (for normal Arduino installations, this
|
|
# is the lib/targets/arduino sub-directory).
|
|
#
|
|
# 4. Modify the line containing "PORT" to refer to the filename
|
|
# representing the USB or serial connection to your Arduino board
|
|
# (e.g. PORT = /dev/tty.USB0). If the exact name of this file
|
|
# changes, you can use * as a wildcard (e.g. PORT = /dev/tty.USB*).
|
|
#
|
|
# 5. At the command line, change to the directory containing your
|
|
# program's file and the makefile.
|
|
#
|
|
# 6. Type "make" and press enter to compile/verify your program.
|
|
#
|
|
# 7. Type "make upload", reset your Arduino board, and press enter to
|
|
# upload your program to the Arduino board.
|
|
#
|
|
# $Id$
