## Namespaces

QtCanBus | 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

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

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
