# Target MCU: Atmel Atmega16-16

#change DEVICE o the name of your gnusb (as defined in usbconfig.h)
DEVICE = gnusb

COMPILE = avr-gcc -Wall -Os -Iusbdrv -I. -mmcu=atmega16 #-DDEBUG_LEVEL=2
# NEVER compile the final product with debugging! Any debug output will
# distort timing so that the specs can't be met.

OBJECTS = usbdrv/usbdrv.o usbdrv/usbdrvasm.o usbdrv/oddebug.o gnusb.o main.o
# Note that we link usbdrv.o first! This is required for correct alignment of
# driver-internal global variables!


# symbolic targets:
all:	main.hex

.c.o:
	$(COMPILE) -c $< -o $@

.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.

.c.s:
	$(COMPILE) -S $< -o $@
