嗨伙计们，这是我第一篇文章，下面是在 C# 中使用串口的基本项目的描述。我创建一个程序，使用写入和读取。与 Texbox 你写任何你想要和点击"发送"，此消息是通过串行通讯 （RS232、 RS485、 RS422，TTL） 发送。每一次，timer1 的事件处于活动状态，将调用 portSerial，并将文本框 （form1 中） 中显示的消息。

几个关于利用傅里叶变换进行谐波分析的代码。有详细的变换过程，比较适合想了解原理的初学者。-Several on the use of Fourier transform for harmonic analysis of the code. The transformation process in detail, more suitable for beginners would like to know the principle.

JTAPI是由Sun公司提出的基于Java语言的应用程序接口。由于JTAPI是基于Java的应用接口，使得JTAPI的对象独立于操作系统和硬件平台，支持跨平台的应用。JTAPI定义了一套类库，包含电话功能和扩充功能。JTAPI结合了传统的电话服务和Web处理能力，具有较强的功能。但是，基于Java的特性，使得JTAPI在拥有强大功能的同时，也失去了普及和推广的基础。-JTAPI by Sun"s Java language on the application program interface. As JTAPI is a Java-based application interface, JTAPI makes the object independent of operating systems and hardware platforms to support cross-platform applications. JTAPI definition of a set of class libraries, including telephone functions and expansion capabilities. JTAPI combination of traditional telephone services and Web processing capability, and a strong function. However, based on Java, which makes JTAPI the powerful functions, lost popularize and promote the foundation.
