pycrc's Introduction

PyCRC MODULES

----------------------
What is PyCRC?
----------------------

    This is an intended port to python for lib_crc library. It requires at least python 2.7.


----------------------
Version & Changelog
----------------------
    1.0 (oct 2011)    Initial launch


----------------------
How can it be used?
----------------------

    The CRC Modules are designed to be used separately (if you wanted for example to use
    only CRC16 you include only the specific file).

    Usage: 
        from CRCModules.CRC16SICK import CRC16SICK
        crcobj = CRC16SICK()
        res = crcobj.calculate("some string")
        print "{:10X}".format(res)

    Check provided pyCRC.py for a more detailed look.
