则打印的信息:
IC卡已插入

20: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

D0: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
E0: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
F0: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
保护寄存器: FFFFFFFFFF
密码寄存器: 07000000
校对密码正确
写示成功
密码已修改为:0x123456
如果：
while((!CARD_IN)&&(p<256))
{
//读16字节
ReadMainMem(p,buff,16); //读IC卡主存
BreakOperate();
Delay10us();
printhex(p);
printf(": ");
for(i = 0;i <= 15; i++)
//printhex(buff);
{
SBUF = '1';
while(!TI);
TI=0;
}
printf("\n");
p+=16;
}
则打印的是:
IC卡已插入
IC数据
00:1111111111111111
为什么不能打印 256 个 1
为什么
p 都不下移了呢？
谢谢！
