Detailed Description

Interface for draw font on LCD.

Typedef Documentation

Font

typedef struct _Font Font

Describes the font (width, height, supported characters, etc.) used by the LCD driver draw API.

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.

Usage

1. Declare a gFont global variable with the necessary Font information.
2. Implement an LCDD_DrawChar function which displays the specified character on the LCD.
3. Use the LCDD_DrawString method defined in draw.h to display a complete string.

Variable Documentation

gFont

const Font gFont

extern

Global variable describing the font being instanced.
