- * Example RF Radio Ping Pair

- * This is an example of how to use the RF24 class.  Write this sketch to two different nodes,
- * connect the role_pin to ground on one.  The ping node sends the current time to the pong node,
- * which responds by sending the value back.  The ping node can then see how long the whole cycle
- * took.

-# 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.
