通过使用S3CEV40实验板的16级灰度液晶显示屏（320*240像素）进行电路设计，掌握液晶屏作为人机接口界面的设计方法，并编写程序实现：

1）　　画出多个矩形框

2）　　显示ASCII字符

3）　　显示汉字字符

4）　　显示一幅鼠标位图

-Through the use of S3CEV40 experiment board level 16 gray liquid crystal display (320 x 240 pixels) circuit design, grasps the LCD screen man-machine interface as the interface design method, and write program realization:

1) draw more rectangular box

2) show ASCII characters

3) shows that Chinese characters

4) shows a mouse bitmap
