# Adapted from Arduino 0011 Makefile by M J Oldfield
#
# Original Arduino adaptation by mellis, eighthave, oli.keller
#
# Version 0.1  17.ii.2009  M J Oldfield
#
#         0.2  22.ii.2009  M J Oldfield
#                          - fixes so that the Makefile actually works!
#                          - support for uploading via ISP
#                          - orthogonal choices of using the Arduino for
#                            tools, libraries and uploading
#
#         0.3  21.v.2010   M J Oldfield
#                          - added proper license statement
#                          - added code from Philip Hands to reset
#                            Arduino prior to upload
#
#         0.4  25.v.2010   M J Oldfield
#                          - tweaked reset target on Philip Hands' advice
#
#         0.5  23.iii.2011 Stefan Tomanek
#                          - added ad-hoc library building
#              17.v.2011   M J Oldfield
#                          - grabbed said version from Ubuntu
#
#         0.6  22.vi.2011  M J Oldfield
#                          - added ard-parse-boards supports
#                          - added -lc to linker opts, 
#                            on Fabien Le Lez's advice
#
#         0.7  12.vii.2011 M J Oldfield
#                          - moved -lm to the end of linker opts,
#	                     to solve Frank Knopf's problem;
#                          - added -F to stty opts: Craig Hollabaugh 
#	                     reckons it's good for Ubuntu
#
#         0.8  12.ii.2012  M J Oldfield
#                          - Patches for Arduino 1.0 IDE:
#                              support .ino files;
#                              handle board 'variants';
#                              tweaked compile flags.
#                          - Build a library from all the system
#                            supplied code rather than linking the .o
#                            files directly.
#                          - Let TARGET default to current directory
#			     as per Daniele Vergini's patch.
#                          - Add support for .c files in system
#                            libraries: Dirk-Willem van Gulik and Evan
#                            Goldenberg both reported this and
#                            provided patches in the same spirit.
#
#          0.9 26.iv.2012  M J Oldfield
#                          - Allow the punter to specify boards.txt
#                            file and parser independently (after
#                            Peplin and Brotchie on github)
#			   - Support user libraries (Peplin's patch)
#                          - Remove main.cpp if NO_CORE_MAIN_CPP is
#                            defined (ex Peplin)
#                          - Added a monitor target which talks to the
#                            Arduino serial port (Peplin's suggestion)
#                          - Rejigged PATH calculations for general 
#                            tidiness (ex Peplin)
#                          - Moved the reset target to Perl for
#                            clarity and better error handling (ex
#                            Daniele Vergini)
#
#          0.10 17.ix.12   M J Oldfield
#            - Added installation notes for Fedora (ex Rickard Lindberg).
#            - Changed size target so that it looks at the ELF object, 
#              not the hexfile (ex Jared Szechy and Scott Howard).
#            - Fixed ARDUNIO typo in README.md (ex Kalin Kozhuharov).
#            - Tweaked OBJDIR handling (ex Matthias Urlichs and Scott Howard).
#            - Changed the name of the Debian/Ubuntu package (ex
#              Scott Howard).
#            - Only set AVRDUDE_CONF if it's not set (ex Tom Hall).
#            - Added support for USB_PID/VID used by the Leonardo (ex Dan
#              Villiom Podlaski Christiansen and Marc Plano-Lesay).
#

# PATHS YOU NEED TO SET UP
#
# I've reworked the way paths to executables are constructed in this
# version (0.9) of the Makefile.
#
# We need to worry about three different sorts of file:
#
# 1. Things which are included in this distribution e.g. ard-parse-boards
#    => ARDMK_DIR
#
# 2. Things which are always in the Arduino distribution e.g. 
#    boards.txt, libraries, &c.
#    => ARDUINO_DIR
#
# 3. Things which might be bundled with the Arduino distribution, but
#    might come from the system. Most of the toolchain is like this:
#    on Linux it's supplied by the system.
#    => AVR_TOOLS_DIR
#
# Having set these three variables, we can work out the rest assuming
# that things are canonically arranged beneath the directories defined
# above.
#
# On the Mac you might want to set:
#
#   ARDUINO_DIR   = /Applications/Arduino.app/Contents/Resources/Java
#   ARDMK_DIR     = /usr/local
#
# On Linux, you might prefer:
#
#   ARDUINO_DIR   = /usr/share/arduino
#   ARDMK_DIR     = /usr/local
#   AVR_TOOLS_DIR = /usr
#
# You can either set these up in the Makefile, or put them in your 
# environment e.g. in your .bashrc
#
# If you don't install the ard-... binaries to /usr/local/bin, but
# instead copy them to e.g. /home/mjo/arduino.mk/bin then set
#   ARDML_DIR = /home/mjo/arduino.mk
#

# DEPENDENCIES
#
# The Perl programs need a couple of libraries:
#    YAML
#    Device::SerialPort
#
########################################################################
#
# STANDARD ARDUINO WORKFLOW
#
# Given a normal sketch directory, all you need to do is to create
# a small Makefile which defines a few things, and then includes this one.
#
# For example:
#
#       ARDUINO_LIBS = Ethernet Ethernet/utility SPI
#       BOARD_TAG    = uno
#       ARDUINO_PORT = /dev/cu.usb*
#
#       include /usr/local/share/Arduino.mk
#
# Hopefully these will be self-explanatory but in case they're not:
#
#    ARDUINO_LIBS - A list of any libraries used by the sketch (we
#                   assume these are in
#                   $(ARDUINO_DIR)/hardware/libraries 
#
#    ARDUINO_PORT - The port where the Arduino can be found (only needed
#                   when uploading
#
#    BOARD_TAG    - The ard-parse-boards tag for the board e.g. uno or mega
#                   'make show_boards' shows a list
#
# Once this file has been created the typical workflow is just
#
#   $ make upload
#
# All of the object files are created in the build-cli subdirectory
# All sources should be in the current directory and can include:
#  - at most one .pde or .ino file which will be treated as C++ after
#    the standard Arduino header and footer have been affixed.
#  - any number of .c, .cpp, .s and .h files
#
# Included libraries are built in the build-cli/libs subdirectory.
#
# Besides make upload you can also
#   make             - no upload
#   make clean       - remove all our dependencies
#   make depends     - update dependencies
#   make reset       - reset the Arduino by tickling DTR on the serial port
#   make raw_upload  - upload without first resetting
#   make show_boards - list all the boards defined in boards.txt
#   make monitor     - connect to the Arduino's serial port
#

#
# SERIAL MONITOR
#
# The serial monitor just invokes the GNU screen program with suitable
# options. For more information see screen (1) and search for 
# 'character special device'.
#
# The really useful thing to know is that ^A-k gets you out!
#
# The fairly useful thing to know is that you can bind another key to
# escape too, by creating $HOME{.screenrc} containing e.g.
#
#    bindkey ^C kill
#
# If you want to change the baudrate, just set MONITOR_BAUDRATE. If you
# don't set it, it defaults to 9600 baud.

# ARDUINO WITH ISP
#
# You need to specify some details of your ISP programmer and might
# also need to specify the fuse values:
#
#     ISP_PROG	   = -c stk500v2
#     ISP_PORT     = /dev/ttyACM0
#
# You might also need to set the fuse bits, but typically they'll be
# read from boards.txt, based on the BOARD_TAG variable:
#     
#     ISP_LOCK_FUSE_PRE  = 0x3f
#     ISP_LOCK_FUSE_POST = 0xcf
#     ISP_HIGH_FUSE      = 0xdf
#     ISP_LOW_FUSE       = 0xff
#     ISP_EXT_FUSE       = 0x01
#
# I think the fuses here are fine for uploading to the ATmega168
# without bootloader.
# 
# To actually do this upload use the ispload target:
#
#    make ispload
