使用汇编语言一个交通灯控制小程序，主要练习串行口通信与中断，定时器中断，外部中断，内附详细解释，通过两个52单片机串行口互联，可控制红黄绿三灯时间，具体为发送机P1口接键盘，可任意设定每个灯两位十进制时间，接收机P1,P2接LED-8屏，同时具有外部中断功能，应对突发事件，呵呵，这个程序是老师布置的作业啦，做完了才发觉原来老师让用c写，偶却好无聊的写成了汇编了-Assembly language of a traffic light control applet, the main practice serial port communication and interrupt, timer interrupt, external interrupt, containing a detailed explanation of the microcontroller through the serial port 52, interconnect the two can control the red yellow and green lights three times, P1 port specifically for the transmitter then the keyboard, can be arbitrarily set each light two decimal time, the receiver P1, P2 access LED-8 screen, also has an external interrupt function, respond to emergencies, huh, huh, this program is the teacher arranged Operating Rights, done did not realize the teacher to use the c write, but good even written a compilation of boring
