Some commons enums that are used in the CAN bus handling part of the QtSerialPort module

Classes

QCanBus	Handles registration and creation of bus plugins
QCanBusDevice	The interface class for CAN bus
QCanBusDevice::Filter	QCanBusDevice::Filter struct defines a filter for CAN bus frames
QCanBusDeviceInfo	Information about CAN bus interfaces
QCanBusFactory	Factory class used as the plugin interface for CAN bus plugins
QCanBusFrame	Container class representing a single CAN frame
QCanBusFrame::TimeStamp	Timestamp information with microsecond precision
QCanDbcFileParser	Can be used to parse DBC files
QCanFrameProcessor	Can be used to decode a QCanBusFrame or to convert the input data into a QCanBusFrame that is ready to be sent to the receiver
QCanFrameProcessor::ParseResult	Struct is used as a return value for the QCanFrameProcessor::parseFrame() method
QCanMessageDescription	Describes the rules to process a CAN message and represent it in an application-defined format
QCanSignalDescription	Describes the rules to extract one value out of the CAN frame and represent it in an application-defined format
QCanSignalDescription::MultiplexValueRange	Defines a range of values for a multiplexor signal
QCanUniqueIdDescription	Describes the rules for accessing a unique identifier in a QCanBusFrame
QModbusClient	The interface to send Modbus requests
QModbusDataUnit	Container class representing single bit and 16 bit word entries in the Modbus register

QModbusDeviceIdentification	Container class representing the physical and functional description of a Modbus server
QModbusExceptionResponse	Container class containing the function and error code inside a Modbus ADU
QModbusPdu	Abstract container class containing the function code and payload that is stored inside a Modbus ADU
QModbusReply	Contains the data for a request sent with a QModbusClient derived class
QModbusRequest	Container class containing the function code and payload that is stored inside a Modbus ADU
QModbusResponse	Container class containing the function code and payload that is stored inside a Modbus ADU
QModbusRtuSerialClient	Represents a Modbus client that uses a serial bus for its communication with the Modbus server
QModbusRtuSerialServer	Represents a Modbus server that uses a serial port for its communication with the Modbus client
QModbusServer	The interface to receive and process Modbus requests
QModbusTcpClient	The interface class for Modbus TCP client device
QModbusTcpConnectionObserver	Represents the interface for objects that can be passed to QModbusTcpServer::installConnectionObserver
QModbusTcpServer	Represents a Modbus server that uses a TCP server for its communication with the Modbus client

Detailed Description

Provides classes to access various serial buses.

For C++ projects include the header appropriate for the current use case, for example applications using the CAN bus device may use

#include <QCanBusDevice>

To use the module with CMake, use the find_package() command to locate the needed module components in the Qt6 package:

find_package(Qt6 COMPONENTS SerialBus REQUIRED)
target_link_libraries(mytarget PRIVATE Qt6::SerialBus)

To use the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:

QT += serialbus
