NI-CAN¶
This interface adds support for CAN controllers by National Instruments.
Warning
NI-CAN only seems to support 32-bit architectures so if the driver can’t be loaded on a 64-bit Python, try using a 32-bit version instead.
Warning
CAN filtering has not been tested thoroughly and may not work as expected.
Bus¶
- class can.interfaces.nican.NicanBus(channel, can_filters=None, bitrate=None, log_errors=True, **kwargs)[source]¶
The CAN Bus implemented for the NI-CAN interface.
Warning
This interface does implement efficient filtering of messages, but the filters have to be set in
__init__()
using thecan_filters
parameter. Usingset_filters()
does not work.- Parameters
channel (
str
) – Name of the object to open (e.g. “CAN0”)can_filters (
Optional
[Sequence
[Union
[CanFilter
,CanFilterExtended
]]]) – Seecan.BusABC.set_filters()
.log_errors (
bool
) – If True, communication errors will appear as CAN messages withis_error_frame
set to True andarbitration_id
will identify the error (default True)
- Raises
can.CanInterfaceNotImplementedError – If the current operating system is not supported or the driver could not be loaded.
can.interfaces.nican.NicanInitializationError – If the bus could not be set up.
