# Vector

This interface adds support for CAN controllers by Vector.

By default this library uses the channel configuration for CANalyzer. To use a different application, open Vector Hardware Config program and create a new application and assign the channels you may want to use. Specify the application name as `app_name='Your app name'` when constructing the bus or in a config file.

Channel should be given as a list of channels starting at 0.

Here is an example configuration file connecting to CAN 1 and CAN 2 for an application named “python-can”:

    [default]
    interface = vector
    channel = 0, 1
    app_name = python-can

If you are using Python 2.7 it is recommended to install pywin32, otherwise a slow and CPU intensive polling will be used when waiting for new messages.

## Bus

class can.interfaces.vector.VectorBus(channel, can_filters=None, poll_interval=0.01, receive_own_messages=False, bitrate=None, rx_queue_size=16384, app_name='CANalyzer', serial=None, fd=False, data_bitrate=None, sjwAbr=2, tseg1Abr=6, tseg2Abr=3, sjwDbr=2, tseg1Dbr=6, tseg2Dbr=3, **kwargs)

  The CAN Bus implemented for the Vector interface.

  Parameters

    - channel (list) – The channel indexes to create this bus with. Can also be a single integer or a comma separated string.

    - poll_interval (float) – Poll interval in seconds.

    - bitrate (int) – Bitrate in bits/s.

    - rx_queue_size (int) – Number of messages in receive queue (power of 2). CAN: range 16…32768 CAN-FD: range 8192…524288

    - app_name (str) – Name of application in Hardware Config. If set to None, the channel should be a global channel index.

    - serial (int) – Serial number of the hardware to be used. If set, the channel parameter refers to the channels ONLY on the specified hardware. If set, the app_name is unused.

    - fd (bool) – If CAN-FD frames should be supported.

    - data_bitrate (int) – Which bitrate to use for data phase in CAN FD. Defaults to arbitration bitrate.
