附三：CRC 校验函数
Little-Endian Mode
/*message：data pointerlen ：data lengthreturn ：32bits CRC Value*/
uint32 GetCRC(void* message, uint16 len)
{
uint32 CRCFull = 0xFFFF;
uint8 CRCLSB;
int i = 0, j = 0;
uint8 *mess = message;
for (i = 0; i < len; i++) {
CRCFull = (uint16)(CRCFull ^ mess[i]);
for (j = 0; j < 8; j++) {
CRCLSB = (uint8)(CRCFull & 0x0001);
CRCFull = (uint16)((CRCFull >> 1) & 0x7FFF);
if (CRCLSB == 1) CRCFull = (uint16)(CRCFull ^ 0xA001);
}
}
return CRCFull;
}

要编写数据用的crc校验 但是这个东西怎么用，vs的话会各种报错。（楼下放图）
