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.
basysKom recently extended this plugin to also accept PEM-based input. PEM is a file format used for certificates and keys which is specified by an RFC and is a preferred format for a lot of open source software. The pull request has been merged and our contribution is available from the 1.1 branch (and will also hit the master branch soon).
In this blog we will cross compile Flutter for a generic ARMv7 Embedded Linux target. We will prepare the sdk, compile flutter and in the end run some demos.
The open62541 OPC UA stack with its Pub-Sub extension now supports MQTT over TLS as well as MQTT-brokers requiring a login (contributed by basysKom). This allows the direct communication between open62541 and the Azure IoT Hub and therefore highly simplifies the connection of OPC UA based IoT Devices to the cloud.
The Device Provisioning Service is a managed service running in the Azure cloud which supports automatic provisioning of IoT devices for IoT Hub.
The following sections will give a short introduction to the most important features of the Device Provisioning Service.
We are developing innovative applications, provide comprehensive consulting, hands-on coaching, and qualificatory training for capital and consumer goods companies. Our customers value our agile approach, our transparent processes, and our high standards.
Due to our own knowledge and our extensive experiences we are convinced of the advantages of open source software for our customers.
