Bus

class can.interfaces.iscan.IscanBus(channel, bitrate=500000, poll_interval=0.01, **kwargs)

Bases: can.bus.BusABC

isCAN interface

Parameters:

• channel (int) – Device number
• bitrate (int) – Bitrate in bits/s
• poll_interval (float) – Poll interval in seconds when reading messages

send(msg, timeout=None)

Transmit a message to the CAN bus.

Override this method to enable the transmit path.

Parameters:

• msg (can.Message) – A message object.
• timeout (float or None) – If > 0, wait up to this many seconds for message to be ACK’ed or for transmit queue to be ready depending on driver implementation. If timeout is exceeded, an exception will be raised. Might not be supported by all interfaces. None blocks indefinitly.

Raises:

can.CanError – if the message could not be sent

shutdown()

Called to carry out any interface specific cleanup required in shutting down a bus.

exception can.interfaces.iscan.IscanError(function, error_code, arguments)
