# DEVICE ....... The AVR device you compile for
# CLOCK ........ Target AVR clock rate in Hertz, not needed when F_CPU is defined in the main file
# 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.
