Design and Implementation of FPGA-Based Touchscreen Control Panel: Cost-Effective, High-Performance and Flexible Solution

Abstract

With the rapid development of technology, touch screens have become an integral part of our lives. Touchscreen panels offer high customization, fast response times, and enhanced user experience, providing flexible and powerful solutions for various usage scenarios. Their widespread use, especially in smartphones, tablets, and other smart devices, offers a direct and intuitive way to interact with users. In this study, customizable, efficient and cost-effective touchscreen control panels (TSCPs) have been developed using a Field-Programmable Gate Array (FPGA). A scenario has been created for the use of the developed TSCP in a 4-room building applicable to a home, office, or similar environment. In this scenario, each room of the building is equipped with TSCPs integrated with an STM32 microcontroller and GOWIN FPGA. The main control card is also designed to be placed in the electrical panel at the building entrance to control this building from a central location. Communication is provided between the TSCPs in each room and the main control card via RF communication. The designed TSCPs can also be controlled by voice or manually through the developed mobile application. The cost analysis of the TSCP developed in this study shows that it is highly cost-effective compared to commercial products.
