QtSerialBus is a new Qt module, introduced as a technical preview in Qt 5.6.0. It supports two serial interface protocols that are commonly used on embedded systems: CAN bus and Modbus. This talk will introduce QtSerialBus, starting with background on the CAN bus and Modbus interface protocols, and the currently supported platforms, drivers, and hardware. The Qt Serial Bus C++ APIs will be presented and some code examples shown, as well as a demonstration of some sample applications running. Areas of possible future work will be discussed as well as references to more information.
