说明： 1.硬件连接：
数据开关的8P插座与P0口的8P插座相连接，发光二极管的8P插座与P1相连接。
2.实验现象：
拨动数据开关为1时，对应的发光二极管亮；为0时，对应的发光二极管灭。
注：在单片机最小系统面板上有SW2为EA与VCC短接块，一般STC单片机EA不接高电平也默认是片内程序存储器。在这里建议用短接冒接高电平，使STC单片机工作更稳定。
(1. Hardware connection:
8p socket of data switch is connected with 8p socket of P0 port, 8p socket of LED is connected with P1.
2. Experimental phenomena:
When the data switch is set to 1, the corresponding LED is on; when it is 0, the corresponding LED is off.
Note: SW2 is the short-circuit block between EA and VCC on the smallest system panel of single-chip microcomputer. Generally, the EA of STC single-chip microcomputer is not connected to high-level, which is also the on-chip program memory by default. In this paper, it is suggested to connect the high-level with the short-circuit jumper to make the STC microcontroller work more stable.)
