canlib - a Python wrapper for Kvaser CANlib
Supported Libraries and Installation
The Python canlib module wraps the Kvaser CANlib API in order to make it easy to control most aspects of any Kvaser CAN interface. For more information about Kvaser please go to https://www.kvaser.com/.
The latest version of this package is available on the Kvaser Download page (pycanlib.zip).

Installation
Install the Python package from PyPI using e.g. pip:
$ pip install canlibIf you have downloaded the package zip file from the Kvaser Download page, first unzip pycanlib.zip. Then navigate to the unzipped pycanlib using the command line. It should contain the file canlib-x.y.z-py2.py3-none-any.whl, where x,y,z are version numbers. Run the following command:
$ pip install canlib-x.y.z-py2.py3-none-any.whlThe Kvaser CANlib DLLs or shared libraries also need to be installed:
Windows
On Windows, first install the canlib32.dll by downloading and installing “Kvaser Drivers for Windows” which can be found on the Kvaser Download page (kvaser_drivers_setup.exe) This will also install kvrlib.dll, irisdll.dll, irisflash.dll and libxml2.dll used by kvrlib.
The “Kvaser CANlib SDK” also needs to be downloaded from the same place (canlib.exe) and installed if more than just CANlib will be used. This will install the rest of the supported library dll’s.
The two packages, “Kvaser Drivers for Windows” and “Kvaser CANlib SDK”, contains both 32 and 64 bit versions of the included dll’s.
Linux
On Linux, first install the libcanlib.so by downloading and installing “Kvaser LINUX Driver and SDK” which can be found on the Kvaser Download page (linuxcan.tar.gz).
If more than just CANlib will be used, the rest of the supported libraries will be available by downloading and installing “Linux SDK library” (kvlibsdk.tar.gz).
Usage
Example of using canlib to list some information about connected Kvaser devices:
from canlib import canlib
num_channels = canlib.getNumberOfChannels()
print(f"Found {num_channels} channels")
for ch in range(num_channels):
chd = canlib.ChannelData(ch)
print(f"{ch}. {chd.channel_name} ({chd.card_upc_no} / {chd.card_serial_no})")Which may result in:
Found 4 channels
0. Kvaser Memorator Pro 2xHS v2 (channel 0) (73-30130-00819-9 / 12330)
1. Kvaser Memorator Pro 2xHS v2 (channel 1) (73-30130-00819-9 / 12330)
2. Kvaser Virtual CAN Driver (channel 0) (00-00000-00000-0 / 0)
3. Kvaser Virtual CAN Driver (channel 1) (00-00000-00000-0 / 0)Support
