##Canmatrix is a python package to read and write several CAN database formats.##

###About

Canmatrix implements a "Python Can Matrix Object" which describes the can-communication and the needed objects (Boardunits, Frames, Signals, Values, ...) Canmatrix also includes two Tools (canconvert and cancompare) for converting and comparing CAN databases.

There is some outdated german Documentation and windows ".exe" of both scripts at my personal homepage There are several importers (read) and exporters (write) for this object.

supported file formats for import:

• .dbc candb / Vector
• .dbf Busmaster (open source!)
• .kcd kayak (open source!)
• .arxml autosar system description
• .yaml dump of the python object
• .xls(x) excel xls-import, works with .xls-file generated by this lib
• .sym peak pcan can description

supported file formats for export:

• .dbc
• .dbf
• .kcd
• .xls(x)
• .json Canard (open source!)
• .arxml (very basic implementation)
• yaml (dump of the python object)
• sym

###Install instructions Install canmatrix with either "pip install canmatrix" or "python setup.py install"

This installs the canmatrix package into your python installation.

In addition to the canmatrix package there are 2 scripts installed with this package:

1. canconvert:

   converts CAN database formats between all supported formats.

   Example: "canconvert someArSystemdescription.arxml file.dbc"

2. cancompare:

   compares 2 CAN databases (of different or same format).

   Example: "cancompare file1.dbc file2.dbc"

If you are using a *NIX-System, these scripts should be callable from command line

If you are using a Windows system, these scripts are usually installed at the location of your python installation. For example 'C:\python3.4\Scripts' or 'C:\python2.7\Scripts'
