IXXAT Virtual CAN Interface

Interface to IXXAT Virtual CAN Interface V3 SDK. Works on Windows.

Note

The Linux ECI SDK is currently unsupported, however on Linux some devices are supported with Socketcan.

Bus

can.interfaces.ixxat.Bus

alias of IXXATBus

class can.interfaces.ixxat.canlib.IXXATBus(channel, can_filters=None, **config)

The CAN Bus implemented for the IXXAT interface.

Internals

The IXXAT Bus object is a farly straightforward interface to the IXXAT VCI library. It can open a specific device ID or use the first one found.

The frame exchange do not involve threads in the background but is explicitly instantiated by the caller.

  • recv() is a blocking call with optional timeout.
  • send() is not blocking but may raise a VCIError if the TX FIFO is full

RX and TX FIFO sizes are configurable with rxFifoSize and txFifoSize options, defaulting at 16 for both.

The CAN filters act as a “whitelist” in IXXAT implementation, that is if you supply a non-empty filter list you must explicitly state EVERY frame you want to receive (including RTR field). The can_id/mask must be specified according to IXXAT behaviour, that is bit 0 of can_id/mask parameters represents the RTR field in CAN frame. See IXXAT VCI documentation, section “Message filters” for more info.

Hint

Module uses can.ixxat logger and at DEBUG level logs every frame sent or received. It may be too verbose for your purposes.
