* Udp.cpp: Library to send/receive UDP packets.
*
* NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
* 1) UDP does not guarantee the order in which assembled UDP packets are received. This
* might not happen often in practice, but in larger network topologies, a UDP
* packet can be received out of sequence.
* 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
* aware of it. Again, this may not be a concern in practice on small local networks.
* For more information, see http://www.cafeaulait.org/course/week12/35.html

/*
Digital Pot Control
This example controls an Analog Devices AD5206 digital potentiometer.
The AD5206 has 6 potentiometer channels. Each channel's pins are labeled
A - connect this to voltage
W - this is the pot's wiper, which changes when you set it
B - connect this to ground.
The AD5206 is SPI-compatible,and to command it, you send two bytes,
one with the channel number (0 - 5) and one with the resistance value for the
channel (0 - 255).
The circuit:
* All A pins of AD5206 connected to +5V
* All B pins of AD5206 connected to ground
* An LED and a 220-ohm resisor in series connected from each W pin to ground
* CS - to digital pin 10 (SS pin)
* SDI - to digital pin 11 (MOSI pin)
* CLK - to digital pin 13 (SCK pin)

Note:
Not all pins on the Mega and Mega 2560 support change interrupts,

/*
Software serial multple serial test
Receives from the two software serial ports,
sends to the hardware serial port.
In order to listen on a software port, you call port.listen().
When using two software serial ports, you have to switch ports
by listen()ing on each one in turn. Pick a logical time to switch
ports, like the end of an expected transmission, or when the
buffer is empty. This example switches ports when there is nothing
more to read from a port
The circuit:
Two devices which communicate serially are needed.
* First serial device's TX attached to digital pin 2, RX to pin 3
* Second serial device's TX attached to digital pin 4, RX to pin 5
Note:
Not all pins on the Mega and Mega 2560 support change interrupts,
so only the following can be used for RX:
10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
