IC卡读写程序

//注意：单片机的晶振频率选用11.0592MHZ
//IC卡与单片机的引脚在SLE4442.h中定义
//各函数的说明请见SLE4442.h
#include <reg52.h>
#include "SLE4442.h"

//下面为读例子程序
main()
{
	unsigned char RecBuf[256];			//接收缓冲区
	unsigned char ret;					//函数返回值
	ret = ReadCm(0x0,8,RecBuf);			//从0地址开始读8个字节
	//读成功返加0,失败返回1
	ret = 0xAA;					//请在此设置断点查看是否读成功以及读到的数据
	while(1);
}
