Embedded-Based Touch Screen Driver Design and Implementation

With the development of the Internet, embedded systems have become one of the hottest industries at present, and the embedded market still shows a huge demand. People have put forward higher requirements for embedded products, such as stable, intuitive, convenient and easy to operate. Touch screen undoubtedly provides people with great convenience, so in embedded systems, touch screen design with good performance, stable operation and high precision has positive and extensive significance. At the same time, in the embedded field, the Linux operating system's open source code licensing model, easy to customize, easy to cut and port features, making Linux the most popular and most popular operating system in the embedded development platform and application platform. Embedded systems are superior in terms of high specialisation and real-time, with a wide range of application-centric and computer technology-based applications. As today's electronic devices continue to be intelligent, the traditional keyboard, mouse and other human-computer interaction has been unable to meet the needs of people, people want more convenient human-computer interaction tools. The touch screen through the finger touch can achieve the operation of positioning, greatly simplifies the input method of electronic equipment, truly zero distance operation, so the touch screen has been more and more widely used. This paper is based on the Samsung S3C2410 embedded, design and implementation of the touch screen program, to achieve the control and operation of the touch screen, with touch screen sensitivity, positioning touch screen position and other characteristics, to improve the use of touch screen efficiency and user experience. Finally, the feasibility and effectiveness of the design program is verified through experiments.
