# --------------------------------------------------------
# if you write separate C files to include in main
# add their .o targets to the OBJECTS line below
# (e.g. "OBJECTS = main.o myfile.o")
# --------------------------------------------------------
OBJECTS    = main.o m_usb.o m_rf.o m_bus.o
#OBJECTS    = main.o

# --------------------------------------------------------
# if you need to use one of our pre-compiled libraries,
# add it to the line below (e.g. "LIBRARIES = libsaast.a")
# --------------------------------------------------------
LIBRARIES  = 

# --------------------------------------------------------
# Default settings for the M2:
# --------------------------------------------------------
DEVICE     = atmega32u4
CLOCK      = 16000000

# --------------------------------------------------------
# you shouldn't change anything below here,
# unless you really know what you're doing
