If you're using this makefile instead, you'll need to do +# a few things differently: +# +# - Give your program's file a .cpp extension (e.g. foo.cpp). +# +# - Put this line at top of your code: #include <WProgram.h> +# +# - Write prototypes for all your functions (or define them before you +# call them). A prototype declares the types of parameters a +# function will take and what type of value it will return. This +# means that you can have a call to a function before the definition +# of the function. A function prototype looks like the first line of +# the function, with a semi-colon at the end. For example: +# int digitalRead(int pin); +# +# Instructions for using the makefile: +# +# 1. Copy this file into the folder with your sketch. +# +# 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 "ARDUINO" to point the directory that +# contains the Arduino core (for normal Arduino installations, this +# is the lib/targets/arduino sub-directory). +# +# 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. 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. +# +# $Id: Makefile,v 1.7 2007/04/13 05:28:23 eighthave Exp $ + +PORT = /dev/tty.usbserial-* +TARGET = Pd_firmware +ARDUINO = /Applications/arduino-0007 +ARDUINO_SRC = $(ARDUINO)/lib/targets/arduino +ARDUINO_LIB_SRC = $(ARDUINO)/lib/targets/libraries +INCLUDE = -I$(ARDUINO_SRC) -I$(ARDUINO)/tools/avr/avr/include \ + -I$(ARDUINO)/lib/targets/libraries/EEPROM \ + -I$(ARDUINO)/lib/targets/libraries/Firmata \ + -I$(ARDUINO)/lib/targets/libraries +SRC = $(ARDUINO_SRC)/pins_arduino.c $(ARDUINO_SRC)/wiring.c \ + $(ARDUINO_SRC)/WInterrupts.c +CXXSRC = applet/$(TARGET).cpp $(ARDUINO_SRC)/HardwareSerial.cpp \ + $(ARDUINO_LIB_SRC)/EEPROM/EEPROM.cpp \ + $(ARDUINO_LIB_SRC)/Firmata/Firmata.cpp \ + $(ARDUINO_SRC)/WRandom.cpp +MCU = atmega8 +F_CPU = 16000000 +FORMAT = ihex +UPLOAD_RATE = 19200 + +# Name of this Makefile (used for "make depend"). +MAKEFILE = Makefile + +# Debugging format. +# Native formats for AVR-GCC's -g are stabs [default], or dwarf-2. +# AVR (extended) COFF requires stabs, plus an avr-objcopy run. +DEBUG = stabs + +OPT = s + +# Place -D or -U options here +CDEFS = -DF_CPU=$(F_CPU) +CXXDEFS = -DF_CPU=$(F_CPU) + +# Compiler flag to set the C Standard level. +# c89 - "ANSI" C +# gnu89 - c89 plus GCC extensions +# c99 - ISO C99 standard (not yet fully implemented) +# gnu99 - c99 plus GCC extensions +CSTANDARD = -std=gnu99 +CDEBUG = -g$(DEBUG) +CWARN = -Wall -Wstrict-prototypes +CTUNING = -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums +#CEXTRA = -Wa,-adhlns=$(<:.c=.lst) + +CFLAGS = $(CDEBUG) $(CDEFS) $(INCLUDE) -O$(OPT) $(CWARN) $(CSTANDARD) $(CEXTRA) +CXXFLAGS = $(CDEFS) $(INCLUDE) -O$(OPT) +#ASFLAGS = -Wa,-adhlns=$(<:.S=.lst),-gstabs +LDFLAGS = + + +# Programming support using avrdude.
