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

按键扫描 51单片机加8279
8279通过74LS 138译码器扩展4×4键盘、6位显示器。
由3-8译码器对SL0~SL2译出键扫描线,由另一3-8译码器译出显示器的位扫描线,并采用了编码扫描方式。
为了防止出现重键现象,扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式,故8279的中断请求信号IRQ悬空未用。
-Scan button 82,798,279 plus 51 single-chip decoder 74LS 138 through the expansion of 4 × 4 keyboard, the display 6. From 3-8 decoder SL0 ~ SL2 translated to the key scanning line, by another 3-8 decoder translated display scan line, and uses code scanning. In order to prevent the emergence of the phenomenon of re-key, scan the output line does not take part in high level SL3 scan decoding keys. CPU on the 8279 surveillance using the query mode, the 8279 interrupt request signal IRQ left unused.
