How to convert CRC 16 from hexidecimal serie in Python

I have a serie of hexidecimal bytes:

0x81 0x12 0xC0 0x00 0x01 0x05

I need to calculate the CRC 16 of this. An online calcultor gives me:

0x81 0x53 //correct

I use the crcmod python module as follows:

crc16 = crcmod.predefined.mkCrcFun('crc-16')

print crc16('123456789') # works well

print hex(crc16('\x81\x12\xC0\x00\x01\x05')) #EDIT : works aswell!

How can i represent this hexidecimal serie as an ascii string (which the function requieres )

Thank you!

Solution

  • use '\x81\x12\xC0\x00\x01\x05'
