# Arduino makefile
#
# This makefile allows you to build sketches from the command line
# without the Arduino environment (or Java).
# Previous work on this file was done by mellis, eighthave and probably 
# many others.

#
# This is a fork of the original makefiles shipped with Arduino 0009.
# It tries to reassemble the preprocessing which the Arduino IDE does.
# This makefile even allows to create an automatic reset, 
# like the Arduino IDE does on an Arduino Diecimila board!
# No no, you don't have to push that tiny button again and again... ;)
#
#     You should only have to check the first six variables below for 
#     propper settings. That's it.
#
#
# Detailed instructions for using the makefile:
#
#  1. Copy this file into the folder with your sketch. There should be a
#     file with the ending .pde (e.g. foo.pde)
#
#  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 "INSTALL_DIR" to point to the directory that
#     contains the Arduino installation (for Arduino installations in 
#     Mac OSX, this could be /Applications/arduino-0009 ).
#
#  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. 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.
#
#  6. At the command line, change to the directory containing your
#     program's file and the makefile.
#
#  7. Type "make" and press enter to compile/verify your program.
#     In TextMate you can just hit Command-R to trigger make.
#
#  8. Type "make upload", reset your Arduino board, and press enter  to
#     upload your program to the Arduino board.

#
# After this you can specify AVRDUDE_PROGRAMMER = arduino, above.
# On older boards you can manually ad this reset feature. Wire a cable from the
# FTDI 232 Chip's DTR pin (the number differs from package to package, see datasheet) 
# to the RESET line of the ATmega. Inbetween this connection must be a 100nF capacitor.
