Webcrcmod is working fine. You are not giving it the three bytes you think you are giving it. Your str (int (0x5A0001)) is providing seven bytes, which are the ASCII characters 5898241 — the conversion of 0x5a0001 to decimal. To feed it the bytes 0x5a 0x00 0x01, you would instead (as one approach): print hex (crc16 ("5a0001".decode ("hex"))) WebCalculate CRC-8, CRC-16, CRC-32 checksums online. Online CRC Calculator.
