本软件可通过微机并口向用户提供多达12路的标准TTL脉冲信号，同时可进行5路的标准TTL脉冲信号的波形显示。 软件的使用方法极为简单。输出信号时，只要选中或取消引脚号，就能在相应的引脚得到相应的脉冲信号（统一为选中为高电平，取消为低电平），“清零”按钮为对应该组的所有信号清零。 输入信号的波形显示，按“开始”按钮为开始进行显示，“停止”为暂停。 在设置面板中，“数据读入时间间隔”为读入时间的设定。“并行打印端口设置”为显示微机中存在的可用打印端口，并可以设定本软件当前要使用的端口（如只有一个可用端口，就为缺省端口，如有多个可用端口软件自动选择最后一个可用端口为当前使用端口）。 -This software is available through computer parallel port to provide users with up to 12 standard TTL pulse signal path, while the standard 5-way can be TTL pulse signal waveform display. The software is extremely simple to use. The output signal, as long as the select or cancel the pin number, the corresponding pin will be able to get a corresponding pulse signal (uniform selected as high as the abolition of the low), "Clear" button for the right should be group cleared all signals. Input signal waveform display, click "Start" button to begin to display, "stop" for pause. In the settings panel, "data read time interval" to read into the time settings. "Parallel printer port settings" to show the e

ConvertNumber，本程序用以对数字进行进制转换。十分实用的小程序。-ConvertNumber, the procedures used to convert hexadecimal numbers. Very useful applet.

这是一个典型的非数值问题，如果使用非递归算法求解此问题，要设计复杂的算法，编写很长的程序。而使用递归算法可以使整个算法清晰，使程序简洁。本问题分析并建立递归算法的过程是典型的抽取问题本质、建立递归算法 并最终解决非数值问题递归实例。-This is a typical non_numerical value problem.you must design complicated arithmetic and long program if you use non_recursion arithmetic.But if you make use of recursion arithmetic,your arithmetic will be clear.The course of analysing and establish recursion arithmetic is a typical example to take out the principle ,establish recursion arithmetic and solve non_numerical value problem.
