Installation

Install the Python package using e.g. pip:

$ pip install canlib-x.y.z.zip

The Kvaser CANlib DLLs or shared libraries also needs 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 https://www.kvaser.com/downloads-kvaser/. 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 placed and installed if more then 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 https://www.kvaser.com/downloads-kvaser/.

If more than just CANlib will be used, the rest of the supported libraries will be available by downloading and installing kvlibsdk.tar.gz.

Usage

Example of using canlib to list connected Kvaser devices:

from canlib import canlib

num_channels = canlib.getNumberOfChannels()
print("Found %d channels" % num_channels)
for ch in range(0, num_channels):
    chdata = canlib.ChannelData(ch)
    print("%d. %s (%s / %s)" % (ch, chdata.device_name,
                                chdata.card_upc_no,
                                chdata.card_serial_no))

Which may result in:

Found 4 channels
0. Kvaser Memorator Professional HS/HS (channel 0) (73-30130-00351-4 / 12377)
1. Kvaser Memorator Professional HS/HS (channel 1) (73-30130-00351-4 / 12377)
2. Kvaser Virtual CAN Driver (channel 0) (00-00000-00000-0 / 0)
3. Kvaser Virtual CAN Driver (channel 1) (00-00000-00000-0 / 0)
