1、工程的建立
对光盘当中的源文件进行删减即可
2、显示中英文字,需要字库文件
1)将原文件里面的config.h拷贝到inc文件夹当中去,把Font_Libs.c文件拷贝到src文件夹当中去,并且在项目中添加Font_Libs.c文件;
2)在main.c文件前面添加如下代码:(头文件、字库数组申明,函数申明)
#include "config.h"
#include "stdarg.h"
extern unsigned char __VGA[];//为字库添加的声明,英文ASCII编码
extern unsigned char __CHS[];//为字库添加的声明,汉子字库数组
void Lcd_PutHZ(unsigned int x,unsigned int y,unsigned short int QW,unsigned int c,unsigned int bk_c,unsigned int st);//为字库添加的声明
void Lcd_PutASCII(unsigned int x,unsigned int y,unsigned char ch,unsigned int c,unsigned int bk_c,unsigned int st);//为字库添加的声明
void Lcd_printf(unsigned int x,unsigned int y,unsigned int c,unsigned int bk_c,unsigned int st,char *fmt,...);//为字库添加的声明
前面添加如下:(头文件、字库数组申明)
#include "config.h"
#include "stdarg.h"
extern unsigned char __VGA[];
extern unsigned char __CHS[];
