通讯规则:
1:时钟7.3728 MHz/波特率9600/9个数据位/奇校验/1个停止位/硬件多机通讯功能/
2:通讯连接采用硬件MAX485,双向单工
3:每个上行/下行的数据包的字节个数都是一样的(通讯数据量)
4:每个上行/下行的数据包都采用CRC8校验
5:数据接收采用中断+查询的方式
6:总是由主机向从机发送一个数据包,从机收到数据包后向主机回复一个数据包
7:不管是主机还是从机,如果收到的数据包有任何错误,都将丢弃该数据包,等效于没有接收
8:从机之间不能相互通讯,必须通过主机才能交换数据
9:无效地址是0,主机地址是1,从机地址是2.3.4......广播地址是255 -err

一款国产的8051模拟器(全部源代码)
本软件是一款8051模拟器,他的特点是可以模拟多处理器平台,在简单的多工作区间的界面上可以很方便的模拟8051处理器, 最重要的是这个单片机系统可以完全由你自己订制,你甚至可以随意创建自己的多单片机系统,什么SMP 基于串行总线的分布式系统,集群式系统,只要你能想到的,都可以办到,充分发挥你的想象力。现在1.0版本已经基本体现出了这种思想,在以后的版本中将使这一特性变的 更加强大!
http://vchelp.net/copathway/project_view.asp?prj_id=1343-Simulator 8051 (all source code) of the 8051 is a software simulator, he can simulate the characteristics of a multi-processor platform, the more simple interval work on the interface can be easily simulated 8051 processor, the most important is that the SCM system can be entirely your own custom you can even create your own free multi processor systems, based on what SMP Serial Bus distributed systems, cluster systems, as long as you can think of, it can be done, give full play to your imagination. Version 1.0 now has basically reflected this thinking, in the future version of this feature will become even more powerful! Http://vchelp.net/copathway/project_view.asp prj_id = 1343
