Arduino 0017 Makefile

Submitted by ax on Wed, 2009-10-14 18:01

I'm helping Hans with shift brite based project for a musician. He gave me a ring of Shift Brite LEDs with an arduino attached. Normally I prefer to work in vim and using makefiles instead of using an IDE. The Arduino software 0017 shipped with a makefile that gives instructions about how to modify it to work for your project but that still doesn't work.

After a little hunting around and some work I got a working, though not ideal makefile. It currently doesn't rebuild your project after you've saved a new source file if you just do : make upload
You have to type make and then make upload.. OH WELL!

Below is my Makefile and also the .diff so you can see exactly what changed.


# Arduino 0015 Makefile
# Arduino adaptation by mellis, eighthave, oli.keller,
# alex norman [with help from http://code.google.com/p/arduino/issues/detail?id=65#c5]
#
# This makefile allows you to build sketches from the command line
# without the Arduino environment (or Java).
#
# Detailed instructions for using the makefile:
#
# 1. Copy this file into the folder with your sketch. There should be a
# file with the same name as the folder and with the extension .pde
# (e.g. foo.pde in the foo/ folder).
#
# 2. Modify the line containg "INSTALL_DIR" to point to the directory that
# contains the Arduino installation (for example, under Mac OS X, this
# might be /Applications/arduino-0012).
#
# 3. 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*).
#
# 4. Set the line containing "MCU" to match your board's processor.
# Older one's are atmega8 based, newer ones like Arduino Mini, Bluetooth
# or Diecimila have the atmega168. If you're using a LilyPad Arduino,
# change F_CPU to 8000000.
#
# 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.
