# probably good enough. For larger projects a too small cache size can cause
# doxygen to be busy swapping symbols to and from disk most of the time
# causing a significant performance penality.
# If the system has enough physical memory increasing the cache will improve the
# performance by keeping more symbols in memory. Note that the value works on
# a logarithmic scale so increasing the size by one will rougly double the
# memory usage. The cache size is given by this formula:

# 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 dfu = Download the hex file to the device, using dfu-programmer (must
# have dfu-programmer installed).
#
# make flip = Download the hex file to the device, using Atmel FLIP (must
# have Atmel FLIP installed).
#
# make dfu-ee = Download the eeprom file to the device, using dfu-programmer
# (must have dfu-programmer installed).
#
# make flip-ee = Download the eeprom file to the device, using Atmel FLIP
# (must have Atmel FLIP installed).
#
# 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".
#----------------------------------------------------------------------------
# MCU name
MCU = at90usb1287
# Target board (see library BoardTypes.h documentation, USER or blank for projects not requiring
# LUFA board drivers). If USER is selected, put custom board drivers in a directory called
# "Board" inside the application directory.
BOARD = USBKEY
# Processor frequency.
# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency. 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.
# Typical values are:
# F_CPU = 1000000
# F_CPU = 1843200
# F_CPU = 2000000
# F_CPU = 3686400
# F_CPU = 4000000
# F_CPU = 7372800
# F_CPU = 8000000
# F_CPU = 11059200
# F_CPU = 14745600
# F_CPU = 16000000
# F_CPU = 18432000
# F_CPU = 20000000
F_CPU = 8000000
# Input clock frequency.
# This will define a symbol, F_CLOCK, in all source code files equal to the
# input clock frequency (before any prescaling is performed). 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.
#
# If no clock division is performed on the input clock inside the AVR (via the
# CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
