前一阵子做了个IC卡读写程序，可以读写SLE4442系统逻辑加密卡的，本来想在网上找一个，没找到，自己写了一个，为了让后来人可以轻松一点，所以就奉献给大家：） 注释比较少（本人的坏习惯），看起来有点累，不过建议你在自己看之前先熟悉一下SLE4442的协议。 程序是经过测试的，在我的931上工作的很好，有什么问题，发信给我 Ploto_zhu@etang.com-done a while ago, IC card reader procedures, can read and write SLE4442 encryption system logic card, and they would like to find an on-line, could not find himself writing a view to the later can easily point and so on devoted to you :) Notes relatively small (my bad habits), looks a bit tired, but I suggest you look at before their first study SLE4442 agreement. Procedures are tested, in my 931 on the good work and what problems, I wrote to Ploto_zhu@etang.com

在Windows环境下应用VC++实现PC机与单片机的几种串行通信方法，给出了用Visual C++6.0编写的PC机程序和用C51编写的单片机通信程序。经实际应用系统运行稳定可靠。-In the Windows environment application VC++ Realize PC machine with several single-chip serial communication method using Visual C++ 6.0 prepared PC-preparation procedures and the use of C51 microcontroller communication program. Through the practical application of system operation is stable and reliable.

使用protel99软件编辑的原理电路图，希望对各位有助于电路图的学习和开发-The use of the principle of circuit protel99 software editor, in the hope you will help the study and development of circuit

用中断的方式控制lcd的显示，单片机仍然是h83664十六位单片机。此程序包含单片机的接口的配置以及各种写lcd的子程，使用中断来控制lcd顺序显示A－Z，当然，可以换成其他的显示内容，由于接口程序已经编好，只需要把要显示的内容改一下就可以实现其他内容的显示-With interruption control lcd display, single-chip is still 16 Singlechip h83664. This procedure includes the configuration of single-chip interface and a variety of writing a sub-lcd-way, the use of interrupt to control the order in lcd display A-Z, of course, can be replaced by other display content, as a result of interface procedures have been developed only to To display the contents of change can be achieved about the display of other content
