楼 主:
硬件:有那位大虾用过IC卡SLE4442，请多多指点指点。您好！
我现在正在搞一个项目，其中一个部分使用了IC卡SLE4442。由于对SLE4442的操作过不
太了解，导致本人已苦苦思索了几天却丝毫没有进展。有那位大虾能雪中送炭？下面是本人
思索尝试的程序：本人不知是写入错，还是读出错。有那位大虾能提供详细操作过程说明书
和用汇编例程。我的E-MAIL：zhweli@21cn.com

最基礎的地方就有問題看了下你的 rst 子程序就寫的有問題
我找了一個,看看
讀 I/0 口時,,該這樣
SETB CLK
SETB IO
NOP
NOP
MOV C,IO
RRC A
DELAY5us
