+#----------------------------------------------------------------------------

+# WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.

+#----------------------------------------------------------------------------

+# On command line:

+#

+# make all = Make software.

+#

+# make clean = Clean out built project files.

+#

+# make coff = Convert ELF to AVR COFF.

+#

+# make extcoff = Convert ELF to AVR Extended COFF.

+#

+# make program = Download the hex file to the device, using avrdude.

+#                Please customize the avrdude settings below first!

+#

+# make debug = Start either simulavr or avarice as specified for debugging,

+#              with avr-gdb or avr-insight as the front end for debugging.

+#

+# make filename.s = Just compile filename.c into the assembler code only.

+#

+# make filename.i = Create a preprocessed source file for use in submitting

+#                   bug reports to the GCC project.

+*****************************************************************************

+** ChibiOS/RT port for Atmel AVR ATmega1280.                                **

+*****************************************************************************

+

+** TARGET **

+

+The demo runs on an Arduino Mega board.

+

+** The Demo **

+

+The demo currently just prints the TestThread output on Serial0, which is

+available on the board USB connector (FT232 converter), and toggles the LED

+on PB7 (pin 13 on Arduino IDE) every second.

+

+** Build Procedure **

+

+The demo was built using the GCC AVR toolchain. It should build with WinAVR too!

+

+** Notes **

+

+This demo runs natively so the Arduino bootloader must be removed and the FUSEs

+reprogrammed. The values used for fuses are LFUSE=0xe7 and HFUSE=0x99.
