delphi1 的串口通讯控件，经过改进的

这是非常有挑战性的题目。对于用户输入的任意一个平面函数f(x)，绘制出其函数曲线。这里最关键的技术难点就是如何实现计算表达式的值。在《编译原理》和《数据结构》的书中，都有对表达式运算方法的论述。说实在的，在编译型计算机语言中实现对用户输入表达式的运算是非常困难的。需要对表达式进行扫描，去括号，按照运算符的优先级生成2叉树，然后遍历该树生成逆波兰表达式，再然后通过栈的方法进行运算。如果在表达式中再包含有函数的话......描述起来都麻烦，更不要说用程序实现了:-(-This is a very challenging issue. For user input an arbitrary planar function f (x), mapping out its function curves. Here the most critical technical problems is how to achieve calculated the value of the expression. "Compiling Principle" and "data structure," the book, have right of expression Operational discussed. Indeed, the computer language compiler to achieve expression of the user input operation is very difficult. Need to scan expression to the brackets, in accordance with the priority Operators Generation 2-ary tree, and then traverse the tree generated reverse Polish expression, and then through the stack approach to computing. If the expression again contains the function described ...... these are trouble, not to mention t

51单片机串口调试程序，谢谢大家使用，本人刚出道，希望大家多多包涵-51 microcontroller serial debugging procedures, thank you all use, the title track, I hope you will forgive me

vb语言的串口编程一点滴。-vb serial programming language a bit.

很好用的串口类，可以以块的方式发送，可以以块的方式接收，而且可以一个一个字符的接收-good use of Serial category, to be sent to the block, the block can receive, but a character can be a receiver

在Visual C++.NET下COM+组件的实现- In Visual C NET under COM module realization

好用的串口调试工具，可自定义波特率，这可是一般的没有的-useful debugging tool available from the definition baud rate, but not the general

CAN总线传输，示例代码,利用VC++编写-CAN transmission, sample code, prepared VC

RS232的UART编程，包括波特率发生器模块，串口接受模块，串口发送模块-RS232 programming the UART, including the baud rate generator module, serial module to receive, send serial module

delphi 编写的云镜控制支持PELCO P/D协议的DLL。 支持对云台镜头及辅助开关的操作。直接封装了SPCOM类，调用只需输入COM口号及对应的命令字符及可。-delphi prepared by the Mirror-control support PELCO P/D agreement DLL. Yuntai support for the camera and auxiliary switch operation. Packaging a direct SPCOM category, called keys COM slogan and the corresponding characters can be ordered.

串口调试助手，支持各种数据转换，也可保存接收的数据-Serial debugging assistant to support a variety of data conversion, but also to receive data can be stored
