51单片机实现双机通信自己整理的

1、左边1号机，右边2号机，功能实现1号机程序#include<reg51.h>#define uint unsigned int#define uchar unsigned charsbit p10=P10;uchar a,b,kk;/uchar code d_c=0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0xff;void delay_ms(uchar y)uchar i;while(y-)for(i=0;i<120;i+);void put(uchar x) /发送函数SBUF=x; /SBUF:串行口数据缓冲器wh
