# makefile for the arduino due (works with arduino IDE 1.6.11)

#
|

# USAGE: put this file in the same dir as your .ino file is.
|
||||
# configure the PORT variable and ADIR at the top of the file
|
||||
# to match your local configuration.
|
||||
# Type make upload to compile and upload.
|
||||
# Type make monitor to watch the serial port with gnu screen.
|
||||
#
|
||||
# TODO:
|
||||
# * support libraries
|
||||
# * handle possibly missing files in the currently hard coded ar step
|
||||
# when assembling core.a together.
|
||||
# * see what to do about the $(SAM)/cores/arduino/wiring_pulse_asm.S" add -x assembler-with-cpp
|
||||
# and this one: $(SAM)/cores/arduino/avr/dtostrf.c
