Developing Qt based screens for Hardware Data

                    "Qt" is a cross-platform

               application framework and widget 

           toolkit for creating graphical user interfaces

        (GUIs) and managing high-speed and high-volume

     data. Its flagship language support of C++ makes it

suitable for high performance. It provides proper code structure,

a range of C++ libraries, and UI design options.

 

Our work involved building a process involving client-server communication between the hardware system

and the screens. These screens receive and process data to perform read and write operations, establishing two-way communication where data flows continuously without any gap. The software layer acts as a continuous monitoring and control system.

 

The incoming data from the hardware involved a combination of strings and integers from the hardware to the screen, arriving at intervals of 10-100 ms per unit of data. Our client's initial efforts to develop a software interface using Python lacked the capability to handle the immense data emitted at extremely fast rates. Due to the single-threaded nature of Python, data distribution and the operation of multiple screens simultaneously failed. However, with C++ and its integration with Qt, operational efficiency and responsiveness significantly increased.

 

Our project has enabled us to develop expertise in comprehending the nature of hardware data and devising strategies to process it within the software layer. Our experience extends beyond any specific type of hardware, empowering us to devise solutions for a wide range of customizable requirements.
