Detailed Description#
Each plugin may support one or more interfaces with different capabilities. This class provides information about available functions.
- class PySide6.QtSerialBus.QCanBusDeviceInfo(other)#
- Parameters:
Constructs a copy of other.
- PySide6.QtSerialBus.QCanBusDeviceInfo.alias()#
- Return type:
str
Returns a user defineable alias associated with this CAN bus interface.
Some CAN bus interfaces can have a user defined alias associated. This is mostly done with the CAN hardware vendors tools. The alias allows to identify this hardware later, especially when multiple interfaces are connected.
Note
In contrast to serialNumber() , the alias is not guaranteed to be unique.
If this function is not supported by the CAN plugin, an empty string is returned.

- PySide6.QtSerialBus.QCanBusDeviceInfo.channel()#
- Return type:
int
Returns the sequential channel number of the CAN bus interface, starting with zero. For example, a two channel CAN interface may have the channels 0 and 1. If the interface has only one channel or if no information about the channel is available, zero is returned.
- PySide6.QtSerialBus.QCanBusDeviceInfo.description()#
- Return type:
str
Returns a textual description of the CAN bus interface, if available. Example output: “PCAN USB Pro FD”. If no description is available, an empty string is returned.
- PySide6.QtSerialBus.QCanBusDeviceInfo.hasFlexibleDataRate()#
- Return type:
bool
Returns true, if the CAN bus interface is CAN FD (flexible data rate) capable.
If this information is not available, false is returned.
- PySide6.QtSerialBus.QCanBusDeviceInfo.isVirtual()#
- Return type:
bool
Returns true, if the CAN bus interface is virtual (i.e. not connected to real CAN hardware).
If this information is not available, false is returned.
- PySide6.QtSerialBus.QCanBusDeviceInfo.name()#
- Return type:
str
Returns the interface name of this CAN bus interface, e.g. “can0”.
This corresponds to the interfaceName parameter of createDevice() .
- PySide6.QtSerialBus.QCanBusDeviceInfo.plugin()#
- Return type:
str
Returns the plugin name of this CAN bus interface, e.g. “peakcan”.
This corresponds to the plugin parameter of createDevice() .
- PySide6.QtSerialBus.QCanBusDeviceInfo.serialNumber()#
- Return type:
str
Returns the serial number of the CAN bus interface as string, if available. Otherwise, an empty string is returned.
