# Arduino Makefile
|
|
# Arduino adaptation by mellis, eighthave, oli.keller
|
|
#
|
|
# Adapted for BSD make(1) by Seth Wright (seth@crosse.org)
|
|
# Adapted for OpenBSD ports by Chris Kuethe (ckuethe@openbsd.org)
|
|
#
|
|
# This makefile allows you to build sketches from the command line
|
|
# without the Arduino environment (or Java).
|
|
#
|
|
# Detailed instructions for using the makefile:
|
|
#
|
|
# 1. Copy this file into the folder with your sketch. There should be a
|
|
# file with the same name as the folder and with the extension .ino
|
|
# (e.g. foo.ino in the foo/ folder).
|
|
#
|
|
# 2. Modify the line containing "PORT" to refer to the filename
|
|
# representing the USB or serial connection to your Arduino board
|
|
# (e.g. PORT = /dev/tty.USB0). If the exact name of this file
|
|
# changes, you can use * as a wildcard (e.g. PORT = /dev/tty.usb*).
|
|
#
|
|
# 3. Set the line containing "MCU" to match your board's processor.
|
|
# Older one's are atmega8 based, newer ones like Arduino Mini, Bluetooth
|
|
# or Diecimila have the atmega168. If you're using a LilyPad Arduino,
|
|
# change F_CPU to 8000000.
|
|
#
|
|
# 4. At the command line, change to the directory containing your
|
|
# program's file and the makefile.
|
|
#
|
|
# 5. Type "make" and press enter to compile/verify your program.
|
|
#
|
|
# 6. Type "make upload", reset your Arduino board, and press enter to
|
|
# upload your program to the Arduino board.
|
|
