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)
