# Qt Serial Bus C++ Classes

Provides classes to read and write serial bus data. More...

This module was introduced in Qt 5.8.

## 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
QCanBusFactoryV2 | 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
QModbusClient | The interface to send Modbus requests
QModbusDataUnit | Container class representing single bit and 16 bit word entries in the Modbus register
QModbusDevice | The base class for Modbus classes, QModbusServer and QModbusClient
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
QModbusRtuSerialMaster | Represents a Modbus client that uses a serial bus for its communication with the Modbus server
QModbusRtuSerialSlave | 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>

The .pro file should have the serialbus keyword added

     QT += serialbus
