# Hey Emacs, this is a -*- makefile -*-
#
# WinAVR makefile written by Eric B. Weddington, J�rg Wunsch, et al.
# Released to the Public Domain
# Please read the make user manual!
#
# Additional material for this makefile was submitted by:
#  Tim Henigan
#  Peter Fleury
#  Reiner Patommel

#
# abused by
# psycorama
#
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#

##
## mitch hack:
## flash another source file: just call "make synth.flash" for example
## also: easier configuration ("include"ing) with multiple projects
##

## ?= sets defaults only when undefined - you can simply overwrite them beforehand

# MCU name (eg "atmega168" or "attiny85")
MCU ?= UNDEFINED

# Main Oscillator Frequency (eg 16000000 or 12000000)
# This is used to define F_OSC in all assembler and c-sources.
F_OSC ?= UNDEFINED

# Output format. (can be srec, ihex, binary)
FORMAT ?= ihex

# Target file name (without extension).
TARGET ?= main

# List C source files here. (C dependencies are automatically generated.)
SRC ?= $(TARGET).c

# 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.
ASRC ?= 

# Optimization level, can be [0, 1, 2, 3, s]. 
# 0 = turn off optimization. s = optimize for size.
# (Note: 3 is not always the best optimization level. See avr-libc FAQ.)
OPT ?= s

# Compiler flag to set the C Standard level.
# c89   - "ANSI" C
# gnu89 - c89 plus GCC extensions
# c99   - ISO C99 standard (not yet fully implemented)
# gnu99 - c99 plus GCC extensions
CSTANDARD ?= -std=gnu99

# Compiler flags.
#  -g*:          generate debugging information
#  -O*:          optimization level
#  -f...:        tuning, see GCC manual and avr-libc documentation
#  -Wall...:     warning level

#             for use in COFF files, additional information about filenames
#             and function names needs to be present in the assembler source
