37/**
38 *
39 * \section Purpose
40 *
41 * The font.h files declares a font structure and a LCDD_DrawChar function
42 * that must be implemented by a font definition file to be used with the
43 * LCDD_DrawString method of draw.h.
44 *
45 * The font10x14.c implements the necessary variable and function for a 10x14
46 * font.
47 *
48 * \section Usage
49 *
50 * -# Declare a gFont global variable with the necessary Font information.
51 * -# Implement an LCDD_DrawChar function which displays the specified
52 *    character on the LCD.
53 * -# Use the LCDD_DrawString method defined in draw.h to display a complete
54 *    string.
