##### This Makefile will make compiling Atmel AVR 
##### micro controller projects simple with Linux 
##### or other Unix workstations and the AVR-GCC 
##### tools.
#####
##### It supports C, C++ and Assembly source files.
#####
##### Customize the values as indicated below and :
##### make
##### make disasm 
##### make stats 
##### make hex
##### make writeflash
##### make gdbinit
##### or make clean
#####
##### See the http://electrons.psychogenic.com/ 
##### website for detailed instructions

##### Customize the values in this section for #####

# Name of target controller 
# (e.g. 'at90s8515', see the available avr-gcc mmcu 
# options for possible values)
MCU=atmega8515

# Name of our project
# (use a single word, e.g. 'myproject')
PROJECTNAME=lcd_test

# Source files
# List C/C++/Assembly source files:
# (list all files to compile, e.g. 'a.c b.cpp as.S'):
# Use .cc, .cpp or .C suffix for C++ files, use .S 
# (NOT .s !!!) for assembly source code files.
PRJSRC=lcd_driver_KS0107.c lcd_graphics.c test_lcd_main.c

# additional includes (e.g. -I/path/to/mydir)
INC=-I/usr/local/avr/include

# libraries to link in (e.g. -lmylib)
LIBS=-L/usr/local/avr/lib

# Optimization level, 
# use s (size opt), 1, 2, 3 or 0 (off)
OPTLEVEL=s

#####      AVR Dude 'writeflash' options       #####
#####  If you are using the avrdude program
#####  (http://www.bsdhome.com/avrdude/) to write
#####  to the MCU, you can set the following config
#####  options and use 'make writeflash' to program
#####  the device.


# programmer id--check the avrdude for complete list
# of available opts.  These should include stk500,
# avr910, avrisp, bsd, pony and more.  Set this to
# one of the valid "-c PROGRAMMER-ID" values 
# described in the avrdude info page.
# 
AVRDUDE_PROGRAMMERID=stk500v2

PROGRAMMER_MCU=atmega8535

# port--serial or parallel port to which your 
# hardware programmer is attached
#
AVRDUDE_PORT=/dev/ttyS1
