CSSE2010 Makefile

Makefile

# Name: Makefile
# Author: Joel Addison

# This is a prototype Makefile. Modify it according to your needs.
# You should at least check the settings for
# DEVICE ....... The AVR device you compile for
# CLOCK ........ Target AVR clock rate in Hertz
# OBJECTS ...... The object files created from your source files. This list is
#                usually the same as the list of source files with suffix ".o".
# PROGRAMMER ... Options to avrdude which define the hardware you use for
#                uploading to the AVR and the interface where this hardware
#                is connected. We recommend that you leave it undefined and
#                add settings like this to your ~/.avrduderc file:
#                   default_programmer = "stk500v2"
#                   default_serial = "avrdoper"
# FUSES ........ Parameters for avrdude to flash the fuses appropriately.

# Use atmega324pa, as it is available for programming (324a is not available).
DEVICE     = atmega324pa
CLOCK      = 8000000
PROGRAMMER = -c avrispmkII -P usb
OBJECTS    = project.o buttons.o game.o ledmatrix.o scrolling_char_display.o serialio.o spi.o terminalio.o timer0.o score.o lives.o ssd.o
FUSES      = -U hfuse:w:0xd9:m -U lfuse:w:0x24:m

# ATMega8 fuse bits used above (fuse bits for other devices are different!):
# Example for 8 MHz internal oscillator
# Fuse high byte:
# 0xd9 = 1 1 0 1   1 0 0 1 <-- BOOTRST (boot reset vector at 0x0000)
#        ^ ^ ^ ^   ^ ^ ^------ BOOTSZ0
#        | | | |   | +-------- BOOTSZ1
#        | | | |   +---------- EESAVE (set to 0 to preserve EEPROM over chip erase)
#        | | | +-------------- CKOPT (clock option, depends on oscillator type)
#        | | +---------------- SPIEN (if set to 1, serial programming is disabled)
#        | +------------------ WDTON (if set to 0, watchdog is always on)
#        +-------------------- RSTDISBL (if set to 0, RESET pin is disabled)
# Fuse low byte:
# 0x24 = 0 0 1 0   0 1 0 0

#        | |  |       +------- CKSEL 3..0 (8M internal RC)
#        | |  +--------------- SUT 1..0 (slowly rising power)
#        | +------------------ BODEN (if 0, brown-out detector is enabled)
#        +-------------------- BODLEVEL (if 0: 4V, if 1: 2.7V)
