从事Profibus的开发人员可以利用改源代码理解profibus协议。添加除通讯以外的代码，很快可以开发出自己的智能节点-engaged in the development staff can use the source code to understand change Profibus agreement. Add except communications code, we will soon be able to develop their own intelligent node

profibus主站及从站源代码，可以作为主从站开发的借鉴-Profibus master and slave source code can be used as a major development from the point of reference

基于80C32单片机+SPC3芯片开发PROFIBUS-DP模块的源代码，对需要利用SPC3芯片开发PROFIBUS-DP从站的朋友非常有帮助，能很容易上手。-SPC3 chip development PROFIBUS-DP slave friend based the 80C32 microcontroller+SPC3 chip development PROFIBUS-DP module source code, very helpful, can be very easy to use
