Wh t i What is communications? i ti ?

Communications

The systems and processes that are used to convey information i f ti f from a source to t a destination, d ti ti especially by means of electricity or radio waves. “tele” = distance Th t The technology h l of f sending di signals i l and d message over a distance using electronic equipment, for example telegraph, example, telegraph telephone, telephone radio radio, television and cellphone

Prerequisites: signals and systems, random process The course focus on the methodologies of system design and analysis, rather than concrete circuits and di implementation. l t ti Pay more attention to essential concepts and physical h i l models d l

Is there a general methodology for designing communication systems? Is there a limit to how fast one can communicate?

CH9121搜索配置协议

CH9121搜索配置协议

CH9121搜索配置协议一、通讯方式CH9121通过UDP广播方式进行网络配置功能。

CH9121广播本地接收端口：50000，上位机广播本地接收端口：60000。

二、通讯结构体CH9121和上位机通讯数据包格式为：typedef struct NET_COMM {unsigned char flag[16]; //通信标识，"CH9121_CFG_FLAG" unsigned char cmd; //命令头unsigned char id[6]; //CH9121MAC地址unsigned char pcid[6]; //PC的MAC地址unsigned char len; //数据区长度unsigned char data[NET_MODULE_DATA_LENGTH]; //数据区缓冲区}net_comm,*pnet_comm;其中在配置和获取配置阶段data[NET_MODULE_DATA_LENGTH]结构如下：__packed typedef struct _NET_DEVICE_CONFIG{DeviceHWConfigS HWCfg; /*网络参数结构体*/DevicePortConfigS PortCfg[2]; /*透传通道参数*/}NetDeviceConfigS,*pNetDeviceConfigS;其中PortCfg[1]为默认开启的透传通道，并且支持手册全部功能，建议使用单通道的时候默认使用此透传通道。

PortCfg[0]为辅助端口，仅支持基本透传功能。

详细结构体定义参考文件：ModuleConfig.h三、通讯过程CH9121上位机配置功能主要包括：1、搜索，2、获取配置 3、配置 4、恢复出厂设置。

经典串口调试助手源程序及串口通信设置

经典串口调试助手源程序及串口通信设置


什么是 VARIANT 数据类型？如何使用 VARIANT 数据类型？ 怎么以十六进制或二进制发送和接收？ 如果还想再深入了解，请看： 串口调试助手源程序及编程详细过程（二）2001.8.26 这是更新后适合本文的源程序（2001.8.25 制作），如果还没有下载源程序，又对本文有兴趣，请 立即 下载 （当然，你看完本文也可以自己做出来，这个程序是接着上一个做的，如果你没下载前面程序， 则没必要再下载了，本程序全部包含）。
描述380无效属性值cominvalidpropertyvalue383属性为只读comsetnotsupported394属性为只读comgetnotsupported8000端口打开时操作不合法comportopen8001超时值必须大于8002无效端口号comportinvalid8003属性只在运行时有效8004属性在运行时为只读8005端口已经打开comportalreadyopen8006设备标识符无效或不支持该标识符8007不支持设备的波特率8008指定的字节大小无效8009缺省参数错误8010硬件不可用被其它设备锁定8011函数不能分配队列8012设备没有打开comnoopen8013设备已经打开8014不能使用comm通知资料内容仅供您学习参考如有不当或者侵权请联系改正或者删除
现在你可以试试程序了，将串口线接好后（不会接？去看看我写的串口接线基本方法），打开串口调试助 手，并将串口设在com2，选上自动发送，也可以等会手动发送。再执行你编写的程序，接收框里应该有数 据显示了。 7.发送数据 先为发送按钮添加一个单击消息即 BN_CLICKED 处理函数，打开 ClassWizard－>Message Maps，选择类 CSCommTestDlg，选择 IDC_BUTTON_MANUALSEND，双击 BN_CLICKED 添加 OnButtonManualsend()函数，并在函数中添加如下代码： void CSCommTestDlg::OnButtonManualsend() { // TODO: Add your control notification handler code here UpdateData(TRUE); //读取编辑框内容 m_ctrlComm.SetOutput(COleVariant(m_strTXData));//发送数据 } 运行程序，在发送编辑框中随意输入点什么，单击发送按钮，啊！看看，在另一端的串口调试助手（或别 的调试工具）接收框里出现了什么。 如果你真是初次涉猎串口编程，又一次成功，那该说声谢谢我了，因为我第一次做串口程序时可费劲了， 那时网上的资料也不好找。开开玩笑，谢谢你的支持，有什么好东西别忘了给我寄一份。 最后说明一下，由于用到 VC 控件，在没有安装 VC 的计算机上运行时要从 VC 中把 mscomm32.ocx、 msvcrt.dll、mfc42.dll 拷到 Windows 目录下的 System 子目录中（win2000 为 System32） 龚建伟 2001.6.20
