| # WinAVR Sample makefile written by Eric B. Weddington, Jörg Wunsch, et al. |
| # Released to the Public Domain |
| # Please read the make user manual! |
| # |
| # Retrofitted for the AVRcam project by John Orlando 6/30/2004 |
| # |
| # |
| # 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". |

| # Revision History: |
| # Date Rel Ver. Notes |
| # 4/10/2004 0.1 Module created |
| # 6/30/2004 1.0 Initial release for Circuit Cellar |
| # contest. |
| # 1/15/2005 1.4 Removed the UartInterfaceAsm file from |
| # file list, since the routine in that |
| # file was added to UartInterface.c. |

| |
| # MCU name |
| MCU = atmega8 |
| |
| # Output format. (can be srec, ihex, binary) |
| FORMAT = ihex |

| # Target file name (without extension). |
| TARGET = AVRcam |

| # Optimization level, can be [0, 1, 2, 3, s]. 0 turns off optimization. |

| # List C source files here. (C dependencies are automatically generated.) |
| #SRC = $(TARGET).c |
| |
| # If there is more than one source file, append them above, or adjust and |
| # uncomment the following: |
| # NOTE: The order of the files here is important...CamInterface.c MUST be |
| # the first file, due to the declaration of an array that needs to be |
| # located at the very beginning of the .noinit section in on-board RAM. |

| # 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. |
