# PATHS YOU NEED TO SET UP
#
# We need to worry about three different sorts of files:
#
# 1. The directory where the *.mk files are stored
# => ARDMK_DIR
#
# 2. Things which are always in the Arduino distribution e.g.
# boards.txt, libraries, etc.
# => ARDUINO_DIR
#
# 3. Things which might be bundled with the Arduino distribution, but
# might come from the system. Most of the toolchain is like this:
# on Linux it is supplied by the system.
# => AVR_TOOLS_DIR
#
# Having set these three variables, we can work out the rest assuming
# that things are canonically arranged beneath the directories defined
# above.
#
# On the Mac with IDE 1.0 you might want to set:
#
# ARDUINO_DIR = /Applications/Arduino.app/Contents/Resources/Java
# ARDMK_DIR = /usr/local
#
# On the Mac with IDE 1.5+ you might want to set:
#
# ARDUINO_DIR = /Applications/Arduino.app/Contents/Java
# ARDMK_DIR = /usr/local
#
# On Linux, you might prefer:
#
# ARDUINO_DIR = /usr/share/arduino
# ARDMK_DIR = /usr/share/arduino
# AVR_TOOLS_DIR = /usr
#
# On Windows declare this environmental variables using the windows
# configuration options. Control Panel > System > Advanced system settings
# Also take into account that when you set them you have to add '\' on
# all spaces and special characters.
# ARDUINO_DIR and AVR_TOOLS_DIR have to be relative and not absolute.
# This are just examples, you have to adapt this variables accordingly to
# your system.
#
# ARDUINO_DIR =../../../../../Arduino
# AVR_TOOLS_DIR =../../../../../Arduino/hardware/tools/avr
# ARDMK_DIR = /cygdrive/c/Users/"YourUser"/Arduino-Makefile
#
# On Windows it is highly recommended that you create a symbolic link directory
# for avoiding using the normal directories name of windows such as
# c:\Program Files (x86)\Arduino
# For this use the command mklink on the console.
#
#
# You can either set these up in the Makefile, or put them in your
# environment e.g. in your .bashrc
#
# If you don't specify these, we can try to guess, but that might not work
# or work the way you want it to.
#
# If you'd rather not see the configuration output, define ARDUINO_QUIET.

# DEPENDENCIES
#
# to reset a board the (python) pySerial program is used.
# please install it prior to continue.
#
########################################################################
#
# STANDARD ARDUINO WORKFLOW
#
# Given a normal sketch directory, all you need to do is to create
# a small Makefile which defines a few things, and then includes this one.
#
# For example:
#
# ARDUINO_LIBS = Ethernet SPI
# BOARD_TAG = uno
# MONITOR_PORT = /dev/cu.usb*
#
# include /usr/share/arduino/Arduino.mk
#
# Hopefully these will be self-explanatory but in case they're not:
#
# ARDUINO_LIBS - A list of any libraries used by the sketch (we
# assume these are in $(ARDUINO_DIR)/hardware/libraries
# or your sketchbook's libraries directory)
#
# MONITOR_PORT - The port where the Arduino can be found (only needed
# when uploading)
#
# BOARD_TAG - The tag for the board e.g. uno or mega
# 'make show_boards' shows a list
#
# If you have your additional libraries relative to your source, rather
# than in your "sketchbook", also set USER_LIB_PATH, like this example:
#
# USER_LIB_PATH := $(realpath ../../libraries)
#
# If you've added the Arduino-Makefile repository to your git repo as a
# submodule (or other similar arrangement), you might have lines like this
# in your Makefile:
#
# ARDMK_DIR := $(realpath ../../tools/Arduino-Makefile)
# include $(ARDMK_DIR)/Arduino.mk
#
# In any case, once this file has been created the typical workflow is just
#
# $ make upload
#
# All of the object files are created in the build-{BOARD_TAG} subdirectory
# All sources should be in the current directory and can include:
# - at most one .pde or .ino file which will be treated as C++ after
# the standard Arduino header and footer have been affixed.
# - any number of .c, .cpp, .s and .h files
#
# Included libraries are built in the build-{BOARD_TAG}/libs subdirectory.
#
# Besides make upload, there are a couple of other targets that are available.
# Do make help to get the complete list of targets and their description
#
########################################################################
#
# SERIAL MONITOR
#
# The serial monitor just invokes the GNU screen program with suitable
# options. For more information see screen (1) and search for
# 'character special device'.
#
# The really useful thing to know is that ^A-k gets you out!
#
# The fairly useful thing to know is that you can bind another key to
# escape too, by creating $HOME{.screenrc} containing e.g.
#
# bindkey ^C kill
#
# If you want to change the baudrate, just set MONITOR_BAUDRATE. If you
# don't set it, it tries to read from the sketch. If it couldn't read
# from the sketch, then it defaults to 9600 baud.
#
########################################################################
#
# ARDUINO WITH ISP
#
# You need to specify some details of your ISP programmer and might
# also need to specify the fuse values:
#
# ISP_PROG = stk500v2
# ISP_PORT = /dev/ttyACM0
#
# You might also need to set the fuse bits, but typically they'll be
# read from boards.txt, based on the BOARD_TAG variable:
#
# ISP_LOCK_FUSE_PRE = 0x3f
# ISP_LOCK_FUSE_POST = 0xcf
# ISP_HIGH_FUSE = 0xdf
# ISP_LOW_FUSE = 0xff
# ISP_EXT_FUSE = 0x01
#
# You can specify to also upload the EEPROM file:
# ISP_EEPROM = 1
#
# I think the fuses here are fine for uploading to the ATmega168
# without bootloader.
#
# To actually do this upload use the ispload target:
#
# make ispload
#
#
########################################################################
#
# ALTERNATIVE CORES
#
# To use alternative cores for platforms such as ATtiny, you need to
# specify a few more variables, depending on the core in use.
#
# The HLT (attiny-master) core can be used just by specifying
# ALTERNATE_CORE, assuming your core is in your ~/sketchbook/hardware
# directory. For example:
#
# ISP_PORT = /dev/ttyACM0
# BOARD_TAG = attiny85
# ALTERNATE_CORE = attiny-master
#
# To use the more complex arduino-tiny and TinyCore2 cores, you must
# also set ARDUINO_CORE_PATH and ARDUINO_VAR_PATH to the core
# directory, as these cores essentially replace the main Arduino core.
# For example:
#
# ISP_PORT = /dev/ttyACM0
# BOARD_TAG = attiny85at8
# ALTERNATE_CORE = arduino-tiny
# ARDUINO_VAR_PATH = ~/sketchbook/hardware/arduino-tiny/cores/tiny
# ARDUINO_CORE_PATH = ~/sketchbook/hardware/arduino-tiny/cores/tiny
#
# or....
#
# ISP_PORT = /dev/ttyACM0
# BOARD_TAG = attiny861at8
# ALTERNATE_CORE = tiny2
# ARDUINO_VAR_PATH = ~/sketchbook/hardware/tiny2/cores/tiny
# ARDUINO_CORE_PATH = ~/sketchbook/hardware/tiny2/cores/tiny
