| /** | |
| * \addtogroup lcdd_font LCD Font Drawing | |
| * | |
| * \section Purpose | |
| * | |
| * The lcd_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_draw_string() method of draw.h. | |
| * | |
| * The font10x14.c implements the necessary variable and function for a 10x14 | |
| * font. | |
| * | |
| * \note Before drawing fonts, <b>canvas</b> should be selected via | |
| * LCDD_SelectCanvas(), or created by LCDD_CreateCanvas(). | |
| * | |
| * \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. | |
| * -# Select or create canvas via LCDD_SelectCanvas() or LCDD_CreateCanvas(). | |
| * -# Use the lcdd_draw_string() method defined in draw.h to display a complete | |
| * string. | |
| * | |
