The program of achieving 16 bit CRC check code:
unsigned int Get_CRC (uchar*pBuf,uchar num)
{
unsigned i,j;
unsigned int wCrc=0xFFFF;
for(i=0;i
＜
num;i++)
{
wCrc^=(unsigned int)(pBuf[i]);
for(j=0;j
＜
8;j++)
{
if(wCrc &1){wCrc
＞＞
=1; wCrc^=0xA001;}
else wCrc
＞＞
=1;
}
}
return wCrc;
}

communication data reading value and corresponding
actual value illustration:
Communication data using hexadecimal format, is divided into long-form shape (32)
and a short-form shape (16) . Read data multiplied the corresponding unit is the actual
measurement data. Eg. RS485 reading A phase volt is 0X00038E28, voltage unit is
0.001V , then the actual vlaue is 23300 (0x00038e28)X0.001V=233.0V
