# Name: Makefile

# This is a prototype Makefile. Modify it according to your needs.

# You should at least check the settings for
|
||||
# DEVICE ....... The AVR device you compile for
|
||||
# CLOCK ........ Target AVR clock rate in Hertz
|
||||
# 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.
