6 # This is a prototype Makefile. Modify it according to your needs.
7 # You should at least check the settings for
8 # DEVICE ....... The AVR device you compile for
9 # CLOCK ........ Target AVR clock rate in Hertz
10 # OBJECTS ...... The object files created from your source files. This list is
11 # usually the same as the list of source files with suffix ".o".
12 # PROGRAMMER ... Options to avrdude which define the hardware you use for
13 # uploading to the AVR and the interface where this hardware
14 # is connected. We recommend that you leave it undefined and
15 # add settings like this to your ~/.avrduderc file:
16 # default_programmer = "stk500v2"
17 # default_serial = "avrdoper"
18 # FUSES ........ Parameters for avrdude to flash the fuses appropriately.
