该程序已经被多次使用，需要两个sja1000 + 51 + pca82c250的通讯模块（本程序是在P2.6和P2.5设置了LED灯来显示是否通讯成功），将源程序（kaobei.hex）下载到51单片机中，上电后通过按下两个模块的复位键，就能看到对应的模块有指示灯显示-The program has been used many times require two sja1000+ 51+ pca82c250 communication module (the program is set in the P2.6 and P2.5 LED lights to show whether the communication success), the source (kaobei.hex) downloaded to the microcontroller 51, after power on by pressing the two modules of the reset button, you can see the corresponding module LED display
