设计一个七段数码显示器,定时显示出生年月(1986.10.30)的后四位(1030)。
功能要求:
1)使8253工作在3方式,产生定时时间间隔,作为显示延长时间。
2)通过数据段定义当前日期或出生年月,控制七段数码管进行显示。
3)通过8255工作在0方式实现字符编码的输出、数位控制等功能,稳定显示出生年月的后四位。
-Seven-Segment assembly language to design a digital display, timer display birthday (1986.10.30) the last four (1030). Functional requirements: 1) to enable the 8253 job at 3 way, resulting in regular time intervals, as the extension of the time show. 2) the definition of data segment through the current date or birthday, control Seven-Segment LED display. 3) through the 8255 job at 0 means the output character encoding, digital control functions, the stability of the four post-show birthday.
