libscrc 0.0.7

Library for calculating CRC8/CRC16/CRC32/CRC64

libscrc is a library for calculating CRC8 CRC16 CRC32 CRC64.

Installation

• Compile and install the library:

  pip3 install libscrc

  or:

  python setup.py build
  python setup.py install

  You will need the administrative privileges to execute the last command.

• After installation you can run unit tests to make sure that the library works fine. Execute:

  python -m libscrc.testmodbus
  python -m libscrc.testcrc64

Usage

In Python 3:

import libscrc
crc16 = libscrc.modbus(b'1234')  # Calculate ASCII of modbus
crc16 = libscrc.modbus(b'\x01\x02')  # Calculate HEX of modbus

You can also calculate CRC gradually:

import libscrc
crc16 = libscrc.xmodem(b'1234')
crc16 = libscrc.xmodem(b'5678', crc16)
