/**
 * \file
 *
 * Interface for draw font on LCD.
 *
 */

/**
 *
 * \section Purpose
 *
 * The font.h files declares a font structure and a LCDD_DrawChar function
 * that must be implemented by a font definition file to be used with the
 * LCDD_DrawString method of draw.h.
 *
 * The font10x14.c implements the necessary variable and function for a 10x14
 * font.
 *
 * \section Usage
 *
 * -# Declare a gFont global variable with the necessary Font information.
 * -# Implement an LCDD_DrawChar function which displays the specified
 *    character on the LCD.
 * -# Use the LCDD_DrawString method defined in draw.h to display a complete
 *    string.
