unsigned char idata i,u=0;
for(i=0;i<8;i++)
{
DQ = 0;
u >>= 1;
DQ = 1;
if(DQ==1)
u |= 0x80;
TempDelay (2);
_nop_();
u>>=1是 u=u>>1的简写 把u向右移一位
u |= 0x80是u=u|0x80的简写 0x80十六进制,换成二进制就是10000000,也就是说U第7个bit置一。
_nop_(); // 产生一条NOP指令 作用:对于延时很短的,要求在us级的,采用“_nop_”函数,这个函数相当汇编NOP指令,延时几微秒
u |= 0x80是u=u|0x80的简写 0x80十六进制,换成二进制就是10000000,也就是说U第7个bit置一。
_nop_(); // 产生一条NOP指令 作用:对于延时很短的,要求在us级的,采用“_nop_”函数,这个函数相当汇编NOP指令,延时几微秒

u>>=1是 u=u>>1的简写 把u向左移一位
u |= 0x80是u=u|0x80的简写 就是把|两边两数各对应的二进位相或 0x80这是个16进制的数,你把它化成2进制的就可以算了
_nop_(); // 产生一条NOP指令 作用:对于延时很短的,要求在us级的,采用“_nop_”函数,这个函数相当汇编NOP指令,延时几微秒本回答被提问者和网友采纳
