说明： 为什么要移植Freemodbus，这个问题需要从两个方面来回答。第一，modbus是一个非常好的应用层协议，它很简洁也相对完善。对于还没有接触过modbus的朋友来说，我非常不建议直接移植freemodbus，应该耐心的从modbus文档入手，并充分把握身边的所有资源，例如PLC的中modbus部分。第二，其实嵌入式系统的通信协议可以自己制定，但是通过实践发现自己定制的协议漏洞百出，尤其是扩展极为困难。我始终认为借鉴他人的经验是很好的途径。借鉴他人成熟的代码，可以减少调试的时间，实现的功能也多了不少。
个人观点，仅供参考。
freemodbus小提示
freemodbus只能使用从机功能。freemodbus更适合嵌入式系统，虽然例子中也有WIN32的例子，如果想要做PC机程序并实现主机功能，推荐使用另一个modbus库——NMODBUS，使用C#开发。同样WINFORM也可以通过自己编写串口代码实现modbus功能，但是这会花费很长的时间，可能是一周也可能是一个月，如果使用现成的代码库，那么开发时间可能只有10分钟。
(Why transplant Freemodbus, this issue needs to be answered in two ways . First , modbus is a very good application layer protocol , it is very simple and relatively perfect. For no contact with modbus friends, I do not recommend direct transplant freemodbus, the patient should start from modbus documents and take full advantage of all the resources around you , for example, part of the modbus PLC. Second, the fact communication protocol embedded systems can develop their own , but through practice found loopholes own custom protocols , especially the expansion is extremely difficult. I have always believed that draw on the experience of others is a good way . Learn from others mature code can reduce debugging time , functions are also a lot more .
Personal point of view , for reference only .
freemodbus Tips
freemodbus only from the machine function . freemodbus more suitable for embedded systems, although there are examples of WIN32 example , if you want )
