钟表显示一．基本设计要求
1 在屏幕上显示一个适当大小的圆形，再圆形道上均匀的分配着60个点，代表1秒—60秒的位置，凡是5倍的点应当比其他的大。
2 以圆中心为轴，画一条斜线代表秒针，采用定时中断方式，每过1秒钟，秒针移动一个位置。
3 定时源可以使用试验箱上的8253。
4 按“ESC”之后，结束演示。
二． 扩展要求
屏幕上显示时、分、秒针，没有使用中断定时方式，采用的是系统实时时间。
三． 课设基本思想
屏幕设置为图形方式，采用模块化编程，主模块显示界面信息，每个子模块负责一个功能，然后通过模块调用来实现。
首先调用画圆及画线子模块显示圆形表盘，及时、分、秒针，然后调用秒针移动子模块式电子钟能够运行。
在秒针移动子模块中，首先通过cos和sin两个功能模块来确定秒针移动的度数，其次分别对秒、分、时进行擦除重写操作，再分别对表盘及圆心进行刷新，这样就实现了时、分、秒针的动态变化。
