说明：  如何编写读/写一个字节的函数呢？ 1. 读一个字节 uchar tmpread(void) //read a byte date 读一个字节 { uchar i,j,dat dat=0 for(i=1 i<=8 i++) { j=tmpreadbit() dat=(j<<7)|(dat>>1) //读出的数据最低位在最前面，这样刚好一个字节在DAT里 } return(dat) //将一个字节数据返回 }
(How to write read/write one byte of the function does? 1. Reading a byte uchar tmpread (void)// read a byte date read one byte (uchar i, j, dat dat = 0 for (i = 1 i < = 8 i++) (j = tmpreadbit () dat = (j < < 7) | (dat> > 1) // read out data at the top of the minimum, this is just one byte in the DAT-ri) return (dat) // will be a word section of data to return))
