自己在VC 6.0下做的串行端口测试软件，感觉挺好用的-VC 6.0 under their own to do serial port test software, I feel very good use

串口调试：这还是个初步的！如果你有兴趣还可以自己再改！如果还有更好的请联系我-serial debugger : This is still preliminary. If you are interested in then they can change! If there is a better contact I

字符仿真终端 通过一个MSComm控件，实现串口字符通信功能。-characters through a terminal simulation MSComm control, Serial characters communications functions.

基于STM32F103C8T6的LoRa模块通信,使用ZLG的SX1276方案，SX1276/77/78 收发器主要采用LoRaTM 远程调制解调器，用于超长距离扩频通信，抗干扰性强，能够最大限度降低电流消耗。借助升特的LoRaTM 专利调制技术，SX1276/77/78 采用低成本的晶体和物料即可获得超过-148dBm 的高灵敏度。此外，高灵敏度与+20dBm 功率放大器的集成使这些器件的链路预算达到了行业领先水平，成为远距离传输和对可靠性要求极高的应用的最佳选择。相较传统调制技术，LoRaTM调制技术在抗阻塞和选择性方面也具有明显优势，解决了传统设计方案无法同时兼顾距离、抗干扰和功耗的问题。

QAM调制的基本原理 QAM调制实际上是幅度调制和相位调制的组合。相位 + 幅度状态定义了一个数字或数 字的组合。QAM的优点是具有更大的符号率，从而可获得更高的系统效率。通常由符号率 确定占用带宽。因此每个符号的比特（基本信息单位）越多，效率就越高。-QAM modulation of the basic principles are in fact QAM modulation amplitude modulation and phase modulation of the portfolio. Phase+ margin status defines a combination of numbers or figures. The advantage of QAM symbols are greater rate, thus the system efficiency will be higher. Symbol rate is usually determined by the occupied bandwidth. Thus each bit symbols (basic units of information) the more the higher the efficiency.

实现的是语音的读入和文本输出，通过构建函数，搭建框架，利用mfc本身的框架结构和语音输入的sdk包，实现语音的读入和文本输出，其中会用到语音输入的各种相关函数，所以要下载相应的speec sdk和speech language sdk安装包，才能调试通过。

是不是觉得OICQ的截面很酷，你想知道是怎么实现的吗？看一遍，说不定你也能做出来！-not think OICQ section cool, you want to know is how to achieve? Howard, perhaps you can come out!

用S7-200PLC的自由口模式和VB中的MSComm控件方便地实现了计算机与S7-200（CPU224）PLC的通讯。计算机作为主站,用户通过计算机可以方便地设置房间的控制指令并向PLC发出控制或监测命令， PLC作为从站来响应计算机发送的指令并采取相应的动作并将房间的电、水、热信息发回到计算机。用户可以通过电脑屏幕实时地监视到房间的电、水、热信息并进行相应的处理。-with S7-200PLC the Free Port Mode and the VB MSComm to realize a trap Computer and S7-200 (CPU224) PLC communications. Computer as a master station, Computer users can easily set up control rooms PLC issued directives to control or monitoring orders, PLC as from the station to respond to orders sent by the computer and take corresponding action will be room for electricity, water, Heat fat information to the computer. The user can screen real-time surveillance of the room electricity, water and heat information and handled accordingly.
