Python生成CRC16MODBUS校验码

from binascii import *
import crcmod#生成CRC16-MODBUS校验码
def crc16Add(read): crc16 &＃61; crcmod.mkCrcFun(0x18005, rev&＃61;True, initCrc&＃61;0xFFFF, xorOut&＃61;0x0000)data &＃61; read.replace(" ", "") #消除空格readcrcout &＃61; hex(crc16(unhexlify(data))).upper()str_list &＃61; list(readcrcout)# print(str_list)if len(str_list) &＃61;&＃61; 5:str_list.insert(2, &＃39;0&＃39;) # 位数不足补0&＃xff0c;因为一般最少是5个crc_data &＃61; "".join(str_list) #用""把数组的每一位结合起来 组成新的字符串# print(crc_data)read &＃61; read.strip() &＃43; &＃39; &＃39; &＃43; crc_data[4:] &＃43; &＃39; &＃39; &＃43; crc_data[2:4] #把源代码和crc校验码连接起来# print(&＃39;CRC16校验:&＃39;, crc_data[4:] &＃43; &＃39; &＃39; &＃43; crc_data[2:4])print(read)return readif __name__ &＃61;&＃61; &＃39;__main__&＃39;:crc16Add("01 06 00 66 00 C8 00 00")


运行结果如下&＃xff08;经校验正确&＃xff09;
