In this blog we explain how to provide OPCUA open62541 as a ffi plugin to Dart and use it in Flutter. We highlight the pros’ and give you the cons.
The umati community did its first open source release of the “umati Dashboard OPC UA Client”. To support this effort basysKom has worked with the umati community and ported the client to the open62541 OPC UA stack.
In this blog post, we give you a step-by-step guide on how to port shader code you might have in your Qt 5 application to Qt 6.
We take a close look how to generate Qt specific code from Swagger/OpenAPI and explain how to integrate the generated code with a Qt Quick Application.
Apache Avro is a framework for data serialization by Apache Hadoop. It is mainly used in big data processing but how does it compare to protobuf? Lets take a look.
Companion specifications complement OPC UA with the goal of fostering interoperability. This article will provide an overview about implementing a Companion Specification with open62541.
So far programs using Qt OPC UA with the open62541 back-end produced quite a bit of chatter on stdout originating from the open62541 stack itself. Unfortunately there was no simple way to get rid of these low-level logs. We now provide a way to control this behavior.
Porting a Qt 5 QML application to Qt 6 doesn’t have to be difficult. We want to share the issues we had and how we solved them. Look out for your shaders and modules.
Something that has traditionally been complicated to achieve in Qt/QML, especially on low end hardware, is high performant list scrolling with complex delegates.
This has recently changed. In Qt 5.15, it is as simple as setting the new QML ListView property called reuseItems to true. For more details, have a look at the documentation.
In this blog post, I will explain how you can implement this feature in Qt Versions prior to 5.15.
The Qt OPC UA module has been ported to CMake and will be part of Qt 6 right from the first release.
In addition to numerous bug fixes and improved test coverage, the open62541 plugin has been updated to open62541 v1.1 and uses OpenSSL for security support, thus removing the dependency on mbedTLS.
