Detailed Description¶

class DataSource¶

This enum represents the placement of the data within the CAN frame.

Constant

Description

QtCanBus.DataSource.Payload

The data will be extracted from the payload.

QtCanBus.DataSource.FrameId

The data will be extracted from the frame ID.

Constant	Description
QtCanBus.DataSource.Payload	The data will be extracted from the payload.
QtCanBus.DataSource.FrameId	The data will be extracted from the frame ID.

class DataFormat¶

This enum represents the possible data formats. The format defines how the value will be extracted from its source.

Constant

Description

QtCanBus.DataFormat.SignedInteger

The signal value is a signed integer.

QtCanBus.DataFormat.UnsignedInteger

The signal value is an unsigned integer.

QtCanBus.DataFormat.Float

The signal value is float.

QtCanBus.DataFormat.Double

The signal value is double.

QtCanBus.DataFormat.AsciiString

The signal value is an ASCII string.

Constant	Description
QtCanBus.DataFormat.SignedInteger	The signal value is a signed integer.
QtCanBus.DataFormat.UnsignedInteger	The signal value is an unsigned integer.
QtCanBus.DataFormat.Float	The signal value is float.
QtCanBus.DataFormat.Double	The signal value is double.
QtCanBus.DataFormat.AsciiString	The signal value is an ASCII string.

class MultiplexState¶

This enum represents the possible multiplex states of a signal.

Constant

Description

QtCanBus.MultiplexState.None

The signal is not used in multiplexing.

QtCanBus.MultiplexState.MultiplexorSwitch

The signal is used as a multiplexor switch, which means that other signals depend on the values of this signal.

QtCanBus.MultiplexState.MultiplexedSignal

The signal is multiplexed by some switch, and therefore its value can only be extracted when the switch has a specific value.

QtCanBus.MultiplexState.SwitchAndSignal

The multiplexor switch of the signal must have the value that enables us to use this signal. When used, the signal also acts as a multiplexor switch for other multiplexed signals.

Constant	Description
QtCanBus.MultiplexState.None	The signal is not used in multiplexing.
QtCanBus.MultiplexState.MultiplexorSwitch	The signal is used as a multiplexor switch, which means that other signals depend on the values of this signal.
QtCanBus.MultiplexState.MultiplexedSignal	The signal is multiplexed by some switch, and therefore its value can only be extracted when the switch has a specific value.
QtCanBus.MultiplexState.SwitchAndSignal	The multiplexor switch of the signal must have the value that enables us to use this signal. When used, the signal also acts as a multiplexor switch for other multiplexed signals.

class UniqueId¶

Represents a CAN unique identifier. The underlying type is quint32.

An enum is used to avoid implicit conversions to or from unsigned int.
