代码说明:

资源描述 这里先传个代码的文件先看看吧。TCP的协议样例如下: 请求和响应带有六个字节的前缀,如下: byte 0:     事务处理标识符 –由服务器复制 –通常为 0 byte 1:     事务处理标识符 –由服务器复制 –通常为 0 byte 2:     协议标识符= 0 byte 3:     协议标识符= 0 byte 4:     长度字段 (上半部分字节) = 0 (所有的消息长度小于256) byte 5:    长度字段  (下半部分字节)   = 后面字节的数量 byte 6:    单元标识符 (原“从站地址”) byte 7:       MODBUS 功能代码 byte 8 on:       所需的数据   因而处理示例“以4的偏移从UI 9读1寄存器”返回5的值将是

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    This book is meant to help the reader learn how to program in C. It contains a tutorial introduction to get new users started as soon as possible, separate chapters on each major feature, and a reference manual. Most of the treatment is based on reading, writing and revising examples, rather than on mere statements of rules. For the most part, the examples are complete, real programs rather than isolated fragments. All examples have been tested directly from the text, which is in machine-readable form. Besides showing how to make effective use of the language, we have also tried where possible to illustrate useful algorithms and principles of good style and sound design.
