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

51单片机P2口接4*4键盘的行线和列线；红灯亮时进行频率输入；绿灯亮时进行占空比输入；频率值暂定在100到60KHZ之间；输入频率和占空比时要输够六位整数，不够的在前面补0；占空比以百比数（0-100）形式存在。-51 Singlechip P2 mouth then 4* 4 keyboard line and column line red light when the frequency of input green when the input duty cycle frequency value is tentatively scheduled for between 100 to 60KHZ input frequency and duty than enough to lose six integers, not enough to fill in front of 0 duty cycle than a few hundred (0-100) form.
