MAG_PIN PIN macro for the reader's port (i.e.. PINC)
MAG_DDR DDR macro for the reader's port (i.e.. DDRC)
MAG_PORT PORT macro for the reader's port (i.e.. PORTC)
The example macros listed above assume that the Track 2 data wire is
connected to pin 0 on port C, the Track 2 clock wire is connected to
pin 3 on port C (similarly for Tracks 1 and 3), and the card loaded
wire is connected to pin 4 on port C.
If the mag-stripe reader you are using only reads one or two tracks,
then set the clock and data pins for the tracks it doesn't read to a
pin that is unused. For example, on the AT90USBKey, any of the pins on
port C that do not have wires attached will be unused since they are
not connected to any onboard devices (such as the joystick or
temperature sensor).
Connecting wires to pins on different ports (i.e.. a data wire to pin 0
on port C and a clock wire to pin 0 on port D) is currently
unsupported. All pins specified above must be on the same port.

*
* The following list indicates what microcontrollers are compatible with this project.
*
* \li AT90USB1287
* \li AT90USB1286
*
* \section Sec_Info USB Information:
*
* The following table gives a rundown of the USB utilization of this project.
*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>

*
* \section Sec_Description Project Description:
*
* Firmware for a USB AVR powered USB TTL magnetic stripe reader (using a card
* reader such as the Omron V3B-4K) by Denver Gingerich. This project is designed
* to be used with the open source Stripe Snoop project at <a>http://stripesnoop.sourceforge.net/</a>.
*
* See <a>http://ossguy.com/ss_usb/</a> for the USB reader hardware project website,
* including construction and support details.
*
* To use, connect your magnetic card reader device to the USB AVR as follows (pin and port mapping may be adjusted
* from the project makefile):
*
* <table>
* <tr>
* <th><b>Signal:</b></th>
* <th><b>AVR Port:</b></th>
* </tr>
* <tr>
* <td>Track 1 Data</td>
* <td>PORTC, Pin 1</td>
* </tr>
* <tr>
* <td>Track 1 Clock</td>
* <td>PORTC, Pin 2</td>
* </tr>
* <tr>
* <td>Track 2 Data</td>
* <td>PORTC, Pin 3</td>
* </tr>
* <tr>
* <td>Track 2 Clock</td>
* <td>PORTC, Pin 0</td>
* </tr>
* <tr>
* <td>Track 3 Data</td>
* <td>PORTC, Pin 5</td>
* </tr>
* <tr>
* <td>Track 3 Clock</td>
* <td>PORTC, Pin 6</td>
* </tr>
* <tr>
* <td>Card Detect</td>
* <td>PORTC, Pin 4</td>
* </tr>
* </table>
*
* This project is based on the LUFA Keyboard project demonstration application, written by Denver Gingerich.
*
* This application uses a keyboard HID driver to communicate the data collected a TTL magnetic stripe reader
* to the connected computer. The raw bitstream obtained from the magnetic stripe reader is "typed" through
* the keyboard driver as 0's and 1's. After every card swipe, the project will send a return key.
*
* \section Sec_Options Project Options
*
* The following defines can be found in this project, which can control the project behaviour when defined, or changed in value.
*

* <th><b>Description:</b></th>
