If the CRC checksum of each byte to be sent is computed on line, it will take a longer time, but it can save the
program space occupied by the table. The code for computing CRC online is as follows:
unsigned int crc_check（unsigned char *data,unsigned char length）
{
int i;
unsigned crc_result=0xffff;
while
（length--）
{
crc_result^=*data++;
for
（i=0;i<8;i++）
{
if
（crc_result&0x01）
{
crc_result=
（crc_result>>1）^0xa001;
}
else
{
crc_result=crc_result>>1;
}
}
}
return
（crc_result=（（crc_result&0xff）<<8）|（crc_result>>8））;
}
