# Name: Makefile
# Author: <insert your name here>

# 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.

DEVICE = atmega328
CLOCK = 16000000
PROGRAMMER = -F -V -c arduino
OBJECTS = main.o
FUSES = #-U hfuse:w:0xd9:m -U lfuse:w:0x24:m
ARDUINO_SERIAL = -P /dev/tty.usbserial-A900fqRc -b 115200

# 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)
#
# For computing fuse byte values for other devices and options see
# the fuse bit calculator at http://www.engbedded.com/fusecalc/

.S.o:
$(COMPILE) -x assembler-with-cpp -c $< -o $@
# "-x assembler-with-cpp" should not be necessary since this is the default
# file type for the .S (with capital S) extension. However, upper case
# characters are not always preserved on Windows. To ensure WinAVR
# compatibility define the file type manually.

# Xcode uses the Makefile targets "", "clean" and "install"
install: flash fuse

# if you use a bootloader, change the command below appropriately:
load: all
bootloadHID main.hex

# If you have an EEPROM section, you must also create a hex file for the
# EEPROM and add it to the "flash" target.

# Targets for code debugging and analysis:
disasm: main.elf
