Apple Remote Sender:
Copyright Casey Callendrello 2008

Notes: 
1) Apple's remotes use the NEC IR protocol, which is better
described here: http://www.sbprojects.com/knowledge/ir/nec.htm
It uses a 38 kHz carrier wave ( hence the OscWrite call) and uses a 
"pulse distance" encoding.  In other words, the LED is ON for the same
amount of time - it is the duration OFF that matters.

The protocol header is a 9ms on, followed by 4.5 ms off.  A '1' value is
.560 ms on, followed by 1.690 ms off. A '0' value is the same on pulse,
followed by .565 ms off.
The 'end' header is a .560 ms on pulse.

2) The total data transmitted is 32 bits. 

****** Remote Code *******
The first byte is the remote ID, 
a number between 0 and 255.

The second byte is the command
Known commands:
0x02: Menu
0x04: Play
0x07: Right
0x08: Left
0x0B: Up
0x0D: Down

The last two bytes are 0x87EE - which identifies this as an Apple device.
