# Arduino 0011 Makefile
# Arduino adaptation by mellis, eighthave, oli.keller
#
# 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 extension .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 example, under Mac OS X, this
#     might be /Applications/arduino-0011).
#
#  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.  If you're using a LilyPad Arduino,
#     change F_CPU to 8000000.
#
#  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.
#
#  8. Type "make upload", reset your Arduino board, and press enter to
#     upload your program to the Arduino board.

# HINT: If you want to use the automatic reset feature which comes with Arduino 
# Diecimila, put the follwoing in your avrdude.conf: 
# (Use the systemwide $(INSTALL_DIR)/tools/avr/etc/avrdude.conf or create a

#     reset = 7;
#     # since Arduino Diecimila the serial DTR line can be used to trigger a reset!
#  ;
#
# 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.
