# How to use this file
# =====================
# (1)
# Make sure you have the Arduino IDE installed (we've tested this on 022 and newer).
# While flash.py does not use the IDE directly it makes use of its tool chain.
# Please verify the following locations are correct for you platform:
if sys.platform == "darwin": # OSX
AVRDUDEAPP = "/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/avrdude"
AVRGCCAPP = "/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/avr-gcc"

AVRSIZEAPP = "/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/avr-size"
AVROBJDUMPAPP = "/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/avr-objdump"

# Define the serial port to the Lasersaur controller as the first argument to this
# script. alternatively you can create a lasaurapp.conf file with the port as
# the first line. Also on OSX and Linux this script usually finds the right port
# automatically.
# (3)
# Compile LasaurGrbl and load it to an Arduino Uno via USB. In the Teminal/Command Line
# from the location of this flash.py type: python flash.py
