# Hey Emacs, this is a -*- makefile -*-
#----------------------------------------------------------------------------
# WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.
# >> Modified for use with the LUFA project. <<
#
# Released to the Public Domain
#
# Additional material for this makefile was written by:
# Peter Fleury
# Tim Henigan
# Colin O'Flynn
# Reiner Patommel
# Markus Pfaff
# Sander Pool
# Frederik Rouleau
# Carlos Lamas
# Dean Camera
# Opendous Inc.
# Denver Gingerich
#
#----------------------------------------------------------------------------
# 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 doxygen = Generate DoxyGen documentation for the project (must have
# DoxyGen installed)
#
# 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.
#
# To rebuild project do "make clean" then "make all".

# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency in Hz. You can then use this symbol in your source code to
# calculate timings. Do NOT tack on a 'UL' at the end, this will be done
# automatically to create a 32-bit value in your source code.
#
# This will be an integer division of F_USB below, as it is sourced by
# F_USB after it has run through any CPU prescalers. Note that this value
# does not *change* the processor frequency - it should merely be updated to
# reflect the processor speed set externally so that the code can use accurate
# software delays.

# This will define a symbol, F_USB, in all source code files equal to the
# input clock frequency (before any prescaling is performed) in Hz. This value may
# differ from F_CPU if prescaling is used on the latter, and is required as the
# raw input clock is fed directly to the PLL sections of the AVR for high speed
# clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
# at the end, this will be done automatically to create a 32-bit value in your
# source code.

# CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
