设计两台单片机系统间的串行通信
（1）甲方P1口连接8个LED灯；
（2）乙方经串行通信输出数据至甲方，甲方根据所接收的数据，在8个LED灯实现流水灯显示；
（3）需采用串行口方式1及中断方式进行数据的发送和接收。(Design of Serial Communication between Two Single Chip Microcomputer Systems
(1) Party A's P1 port is connected with 8 LED lights;
(2) Party B outputs data to Party A through serial communication, and Party A realizes the pipeline lamp display in eight LED lamps according to the received data.
(3) Serial port mode 1 and interrupt mode are needed to transmit and receive data.)
