The Qt Serial Bus API provides classes and functions to access the various industrial serial buses and protocols, such as CAN, ModBus, and others.
To use the module with CMake, use the
find_package() command to locate the needed module components in the
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
These are links to the API reference materials.
|qt.canbus||Enables standard logging inside the Qt CAN Bus classes|
|qt.canbus.plugins||Enables low level logging inside the Qt CAN Bus plugin classes. To set logging for a specific plugin, use "qt.canbus.plugins.pluginname". e.g. "qt.canbus.plugins.socketcan". "qt.canbus.plugins*" affects all plugins.|
|qt.modbus||Enables standard logging inside the Qt Modbus classes|
|qt.modbus.lowlevel||Enables low level logging including individual packet content inside the Qt Modbus classes|
A quick way to enable all Qt Modbus logging is to add the following line to the main() function:
QLoggingCategory::setFilterRules(QStringLiteral("qt.modbus* = true"));
Changes to Qt SerialBus lists important changes in the module API and functionality that were done for the Qt 6 series of Qt.
