Description: P1口输入、输出试验
实验目的
1.学习P1口的使用方法。
2.学习延时子程序的编写和使用。
实验要求
1.P1口做输出口，接八只发光二极管，编写程序，使发光二极管循环点亮。
2.P1口做输入口，接八个扭子开关，以实验机上74LS273做输出口，编写程序读取开关状态，将此状态，在发光二极管上显示出来。
-P1 port input and output test experiment was 1. Learning to use the P1 population. 2. Learning delay the preparation and use of subroutines. Experimental request output 1.P1 I do, and then light-emitting diodes 8, the preparation procedure, so that light-emitting diode light cycle. I do 2.P1 input, and then switch the eight sub-twisting to do experiments on board 74LS273 output read switch programming, and this state, in the light-emitting diode display.
