　　前期工作打好了基础，都已经可以画图了，想要显示鼠标和字符知识需要一个字库就可以了。
一、显示字符
　　新建一个文件夹，叫做font文件夹，以后我们还要增加中文字体的显示等，这样会比较条理。文件夹下新建font.c，font.h，font_code.c，font.c是对显示文字进行操作的一些函数，font_code.c保存有字库数组，font.h头文件。
　　显示字符的理论非常的简单，首先需要一个字库，我把我使用的字库直接传上来了，百度文库下载的，嫌不好看的可以百度字模生成软件，自己生成想要的字体。把这个字库保存在font_code.c，不要忘记声明头文件。

#include "font.h"
const char font_code_global[94][16]={
