由8031内部定时器1，按方式1工作，即作为16位定时器使用

每0.05秒钟T1溢出中断一次。P1口的P1.0-P1.7分别接八个发

光二极管。要求编写程序模拟一时序控制装置。开机后第一

秒钟L1，L3亮，第二秒钟L2，L4亮，第三秒钟L5，L7亮，第四

秒钟L6，L8亮，第五秒L1，L3，L5，L7亮，第六秒钟L2，L4，

L6，L8亮，第七秒钟八个二极管全亮，第八秒钟全灭，以后又

从头开始，L1，L3亮，然后L2，L4亮......一直循环下去。-Internal timer 1 by 8031, a work by the way, that is, to use as a 16-bit timer overflow every 0.05 seconds, T1 interrupt time. P1 port P1.0-P1.7, respectively, then the eight light-emitting diodes. Procedures require the preparation of a timing control device simulation. The first seconds after boot L1, L3-liang, the second a matter of seconds L2, L4-liang, the third seconds, L5, L7-liang, the fourth seconds, L6, L8-liang, the fifth sec L1, L3, L5, L7-liang, Sixth seconds L2, L4, L6, L8-liang, the seventh of eight seconds, the entire light diode, the eighth body seconds later to start from scratch again, L1, L3-liang, and then L2, L4 light ..... . has been the cycle continues.
