# Makefile for ADUC7000 MCU                                  #
# Makefile was adapted from J.Lynch                          #
# Modifcations:                                              #
# * Support for ram and flash run                            #
# * Output format is binary and ihex                         #
# * Choose debug or release configuration                    #
# * Several smaller cleanups                                 #
