In order to achieve the touch screen as the man-machine interface equipment
using SOPC technology
NiosⅡ processor system in FGPA was builted as a touch screen controller. Screen display and touch screen capabilities have been realized by writing NiosⅡ control procedures. The designed planning structure of Display Area has became a relatively common method to the information display and touch functions of the system. It can increase code reusability and versatility
simplify the program design process of display interface
and the system performance and development efficiency was improved.
