Abstract
Touch-screen portable devices as a result of simple, intuitive interface, lightweight, small footprint, convenient and flexible, etc., have been gradually replacing the keyboard to become embedded computer system input device.At the same time, handwriting touch screen technology has the advantages of natural and very intuitive operation, the basic is intuitive, what would like to stress that you can click on, and ease of use, but also can effectively reduce the product size, save space, this operation must be handheld digital future trends in product development. At the same time, embedded touch-screen technology is considered to be the futur of human-computer interaction technology, one of the mainstream, industry-related applications and products is becoming a hot spot. Embedded touch screen in our very broad range of applications, there are public information inquiries and information of city streets. And ARM chips can be such a wide range of applications, its architecture is very suitable for embedded. ARM is the most successful is the first commercial examples of RISC. RISC-based processor architecture designed die size, short development time, development of low cost, easy to achieve high performance. Graduation Project is therefore the subject of the embedded ARM-based touch-screen control system design, the main function of touch screen input.
