Description

pycrc provides CRC reference implementations in Python and a C source code generator. The used CRC variant can be chosen from a fast but space-consuming implementation to slower but smaller versions especially suitable for embedded applications. The models can be freely chosen, and the collection of CRC models lists some of the most popular models by name. The following functions are implemented:

The following variants of the CRC algorithm are supported:

News

Version 0.8.1 released   (17 May 2013)
Version 0.8.1 is a feature release.

Version 0.8 released   (04 January 2013)
Version 0.8 is a bugfix release.

The bitwise-expression generator is an experimental feature, which might one day be almost as fast as the table-driven code but much smaller. At the moment the generated code is bigger and slower than any other algorithm, so use at your own risk.



Version 0.7.11 released   (20 October 2012)
Version 0.7.11 is a minor bugfix release.

Older news can be read in the pycrc news archive.

To Do

pycrc is considered stable code. No new features are planned, but bugs are still fixed and new models added on request.
