* \section Sec_Description Project Description:
*
* Firmware for a USB Virtual Serial to HD44780 LCD controller project, by Simon Foster. This
* project connects a standard HD7780 compatible LCD controller to a PC via a virtual serial
* link, so that data supplied by the host can be written to the display. This project is
* designed to use the Minimum USB AVR board, however it can be modified to suit other hardware
* if desired.
*
* LCD Datasheet: http://www.sparkfun.com/datasheets/LCD/HD44780.pdf \n
* More Information: http://en.wikipedia.org/wiki/HD44780_Character_LCD \n
*
* Below are the connections between the AVR Minimus board and LCD.
