programmer for the STK200.  You can find it on www1.itnet.pl as well.

I'm using the following generic Makefile in my AVR project directory.
Suppose you've got a file named `foo.c' containing the source code,
you can do the following with it:

make foo.s  --  will compile the C code into an assembler file,
                mainly for code review purposes

make foo.bin -- will compile the C code into an ELF file foo.out first,
                then convert it into a raw binary download file foo.bin

make foo.hex -- will compile the C code into an ELF file foo.out first,
                then convert it into an Intel hex file foo.hex

make foo.srec -- will compile the C code into an ELF file foo.out first,
                 then convert it into a Motorola S-record file foo.srec

make clean -- will remove all the intermediate files; caution, it'll
              also clean out .s files!, if you have valuable assembler
              source files in that directory, better name them ending
              in .S (which means an assembler file to be piped through
              the C preprocessor, avr-gcc should know this from the .S
              suffix already)

(`make all' is provided as a no-op.  If you remove those couple of
lines, just calling `make' would default to `make clean', which is
probably not what you want. ;-)
