* \section SSec_Compat Demo Compatibility:
*
* The following list indicates what microcontrollers are compatible with this demo.
*
* - AT90USB1287
* - AT90USB1286
*
* \section SSec_Info USB Information:
*
* The following table gives a rundown of the USB utilization of this demo.
*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>
* <td>Device</td>
* </tr>
* <tr>
* <td><b>USB Class:</b></td>
* <td>Human Interface Device (HID)</td>
* </tr>
* <tr>
* <td><b>USB Subclass:</b></td>
* <td>Keyboard</td>
* </tr>
* <tr>
* <td><b>Relevant Standards:</b></td>
* <td>USBIF HID Standard, USBIF HID Usage Tables</td>
* </tr>
* <tr>
* <td><b>Usable Speeds:</b></td>
* <td>Full Speed Mode</td>

*
* \section SSec_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>
* <td><b>Signal:</b></td>
* <td><b>AVR Port:</b></td>
* </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 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 demo will send a return key.
*
* \section SSec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <td><b>Define Name:</b></td>
* <td><b>Location:</b></td>
* <td><b>Description:</b></td>
* </tr>
* <tr>
* <td>MAX_BITS</td>
* <td>CircularBitBuffer.h</td>
* <td>Gives the maximum number of bits per track which can be buffered by the device for later transmission to a host.</td>
* </tr>
* <tr>
* <td>MAG_T1_CLOCK</td>
* <td>Makefile CDEFS</td>
* <td>Mask for the magnetic card reader's CLOCK line for the reader's track 1 output.</td>
* </tr>
* <tr>
* <td>MAG_T1_DATA</td>
* <td>Makefile CDEFS</td>
* <td>Mask for the magnetic card reader's DATA line for the reader's track 1 output.</td>
