  • LED Pattern Quick Guide

    The LED Pattern Quick Guide for Kvaser Leaf Light HS v2 and Kvaser Leaf v3 provides information on interpreting the device’s status based on the color and behavior of the LEDs.

  • Adding Virtual Channels

    The two virtual channels that comes with the driver installed are connected, working as for example two Leafs connected by a loopback cable.

    If you want more virtual channels, or channels not connected, you can use the Add Hardware Wizard to add a second pair. These will be connected to each other, but not to the first pair.

    1. Press Windows + R, and type hdwwiz and click OK
    2. Click Next, and manual install. Select CAN Hardware (Kvaser) and Next
    3. Scroll down to Kvaser Virtual CAN driver, and then Next until it finishes.

    You should now have an additional pair of virtual channels ready to use.

  • Can I modify the Linux driver?

    Yes, the Linux driver is released under a dual GPL/BSD license, to allow it to be safely used in your projects.
