# 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.
# FUSES ........ Parameters for avrdude to flash the fuses appropriately.

DEVICE     = attiny2313

# ATTiny2313 fuse bits (fuse bits for other devices are different!):

# "-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

# 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

clean:
        rm -f main.hex main.elf $(OBJECTS)

        rm -f main.hex
        avr-objcopy -j .text -j .data -O ihex main.elf 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
        avr-objdump -d main.elf

cpp:
        $(COMPILE) -E main.c
