  43  *  \section Sec_Description Project Description:
  44  *
  45  *  Firmware for a USB AVR powered USB TTL magnetic stripe reader (using a card
  46  *  reader such as the Omron V3B-4K) by Denver Gingerich. This project is designed
  47  *  to be used with the open source Stripe Snoop project at <a>http://stripesnoop.sourceforge.net/</a>.
  48  *
  49  *  See <a>http://ossguy.com/ss_usb/</a> for the USB reader hardware project website,
  50  *  including construction and support details.
  51  *
  52  *  To use, connect your magnetic card reader device to the USB AVR as follows (pin and port mapping may be adjusted
  53  *  from the project makefile):
  54  *

  90  *  This project is based on the LUFA Keyboard project demonstration application, written by Denver Gingerich.
  91  *
  92  *  This application uses a keyboard HID driver to communicate the data collected a TTL magnetic stripe reader
  93  *  to the connected computer. The raw bitstream obtained from the magnetic stripe reader is "typed" through
  94  *  the keyboard driver as 0's and 1's. After every card swipe, the project will send a return key.
