自己制作 考勤机程序 已经验证成功 并有电路图(Produce their own attendance machine program and a circuit has proved to be successful)

我司通原F1型实验箱的二次开发功能是让用户通过自主设计，加深对有关实验内容所涉及的理论知识的理解和掌握。用户在掌握CPLD和DSP开发技术的基础上，以我司提供的实验箱为硬件，自主实现我司通原F1型实验箱已有的及相关的功能。(Our former F1 experimental me through secondary development function is to allow users to independently design and deepen the theoretical knowledge about the contents of the experiment involved to understand and master. Users control CPLD and DSP development technology based on our experimental boxes provided for the hardware, through self-realization of our original F1 experimental me already and related functions.)

基于VB下的FTP源码，可以实现文件的下载和上传(FTP source code based on VB can download and upload files.)

在linux环境下编写一个控制台应用程序，程序中有一个共享的整型变量shared_var，初始值为0；创建一个线程并使其立即与主线程并发执行。新创建的线程与主线程均不断地循环，并输出shared_var 的值。主线程在循环中不断地对shared_var 进行加1操作，即每次循环shared_var 被加1；而新创建的线程则不断地对shared_var 进行减1 操作，即每次循环shared_var 被减1。观察程序运行的结果，并对你看到的现象进行解释。(Written in the linux environment a console application, the program has a shared integer variable shared_var, the initial value of 0 create A thread and make it run concurrently with the main thread immediately. The newly created thread and main thread are constantly circulating, and the output shared_var Value. The main thread in a loop constantly on shared_var are incremented, that is plus 1 for each cycle shared_var and the new line created Process is constantly on the shared_var decremented, that is, each cycle shared_var is decreased by 1. Observe the results of running the program, and you To explain the phenomenon seen.)
