 +===== Makefile =====
 +Hier als Beispiel das verwendete Makefile
 +
 +<code Make Makefile>
 +# Hey Emacs, this is a -*- makefile -*-
 +#
 +# WinAVR Sample makefile written by Eric B. Weddington, J�rg Wunsch, et al.
 +# Released to the Public Domain
 +# Please read the make user manual!
 +#
 +# Additional material for this makefile was submitted by:
 +#  Tim Henigan
 +#  Peter Fleury
 +#  Reiner Patommel
 +#  Sander Pool
 +#  Frederik Rouleau
 +#  Markus Pfaff
 +#
 +# On command line:
 +#
 +# make all = Make software.
 +#
 +# make clean = Clean out built project files.
 +#
 +# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).
 +#
 +# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
 +#                4.07 or greater).
 +#
 +# make program = Download the hex file to the device, using avrdude.  Please
 +#                customize the avrdude settings below first!
 +#
 +# make filename.s = Just compile filename.c into the assembler code only
 +#
 +# To rebuild project do "make clean" then "make all".
 +#
 +
 +
 +# MCU name
 +MCU = atmega8
 +
 +# Output format. (can be srec, ihex, binary)
 +FORMAT = ihex
 +#FORMAT = binary
 +
 +# Target file name (without extension).
 +TARGET = emk-io-board

 +#readraw.c mmc_spi.c fat.c dos.c dir.c
 +
 +
 +# List Assembler source files here.
 +# Make them always end in a capital .S.  Files ending in a lowercase .s
 +# will not be considered source files but generated files (assembler
 +# output from the compiler), and will be deleted upon "make clean"!
 +# Even though the DOS/Win* filesystem matches both .s and .S the same,
 +# it will preserve the spelling of the filenames, and gcc itself does
 +# care about how the name is spelled on its command-line.
 +ASRC =
