# 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
# local $HOME/.avrduderc file)

# id = "arduino";
# desc = "Arduino Serial Bootloader";
# type = stk500;
# 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.
