# Arduino Makefile
# Arduino adaptation by mellis, eighthave, oli.keller
# Modified by Kerry Wong to support NetBeans
# Modified by Rob Gray (Graynomad) for use with Windows and no IDE
# This works in my environment and I use it to program two different
# 328-based boards and a Mega2560. It's not necessarily robust and
# I may have broken something in the original file that I don't use.
#
# This makefile allows you to build sketches from the command line
# without the Arduino environment.
#
# Instructions for using the makefile:
#
# 1. Copy this file into the folder with your sketch. The project code file
# should have a .c extension however the file gets copied to a .cpp before
# compilation so you still write in C++.
#
# 2. Modify the lines between the double ### rows to set the paths
# comm ports etc for your system. EG. c:/progra~1/arduino/arduino-00
# for the Arduino IDE, Note the use of short folder name, don't use
# "Program files" because spaces will break the build.
#
# Set the line containing "MCU" to match your board's processor.
# Typically ATmega328 or ATmega2560. If you're using a LilyPad Arduino,
# change F_CPU to 8000000.
#
# 3. At the command line, change to the directory containing your
# program's file and the makefile.
#
# 4. Type "make" and press enter to compile/verify your program.
# The default make target will also perform the uplode using avrdude.
#
# The first time this is done all required libraries will be built
# and a core.a file will be created in the output folder.
#
# NOTES:
# All output goes into a folder called "output" underneath the working folder.
# The default all: target creates symbol (.sym) and expanded assembly
# (.lss) files and uploads the program.

/**
* Example RF Radio Ping Star Group
*
* This sketch is a more complex example of using the RF24 library for Arduino.
* Deploy this on up to six nodes. Set one as the 'pong receiver' by tying the
* role_pin low, and the others will be 'ping transmit' units. The ping units
* unit will send out the value of millis() once a second. The pong unit will
* respond back with a copy of the value. Each ping unit can get that response
* back, and determine how long the whole cycle took.
*
* This example requires a bit more complexity to determine which unit is which.
* The pong receiver is identified by having its role_pin tied to ground.
* The ping senders are further differentiated by a byte in eeprom.
