可以实现HDLC帧结构中的添零功能，使得信息部分不会和HDLC帧头部分混淆。...

一个很好用的comm类，对于开发串口工作很有帮助，因多次测试没问题！可在98/2000/xp上正常使用-a good use of comm category, serial work for the development of useful, because several tests No problem! In normal use 98/2000/XP

利用西门子的GSM芯片（TC35）的手机模块实现短信的读写，该手机模块可以加入SIM卡，然后就跟手机一样使用了，程序可以通过串口进行控制-The programme use GSM CMOS chip(TC35) module to read and write short message, you can insert SIM card into this module, then it can work as ordinary Mobile phone,the programme can control the module through com port.

可以完成CRC的校验功能,提供16为的循环冗余校验-it can support the check of CRC

云台镜头控制系统 很好用，调试通过，大家一起分享源代码-pan and camera control system is useful, debugging through, we share source code

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

getmywish使用的usb注意：由于用到多串口控制，需要在收到数据时确定是哪个串口来的数据。 下面是串口事件处理函数代码： -getmywish use usb Note : As used Multiport Serial control, the receipt of necessary data to determine which of the serial data. Below are the serial code incident handling functions :
