# Using canlib (CANlib)

The canlib module wraps the CAN bus API (CANlib), which is used to interact with Kvaser CAN devices connected to your computer and the CAN bus. At its core you have functions to set bus parameters (e.g. bit rate), go bus on/off and read/write CAN messages. You can also use CANlib to download and start t programs on supported devices.
