利用8253，8259等芯片设计的一电子时钟，在摁下启动键后，LED数码管上显示当前设定时间并且开始走，实现二十四小时自动循环计时功能，走时准确还有时钟对时功能。
充分运用8259的中断控制功能、8253的定时计数功能及芯片各自的应用编程来实现电子钟的运作。-8253,8259 and other chip design using a electronic clock, in the press after the start button, LED digital tube displays the current setting of time and start walking, to achieve 24 hours automatic cycle timer function, the clock accurate time and still function on time . Full use of the interrupt control functions 8259, 8253 and the chip timing counting their application programming to achieve clock operation.
