Arithmetic of Touch Screen Multi-points Collection Based on MiniGUI

Xiang Yucheng1,Gao Jie2(1.Dept.of Armament Electronics Products,No.58 Research Institute of China Ordnance Industries,Mianyang 621000,China;2.Dept.of Armament Products,No.58 Research Institute of China Ordnance Industries,Mianyang 621000,China)  
For realize the precise adjustment of touch screen,introduce algorithm of touch screen multi-points collection based on MiniGUI in embedded Linux system.The algorithm use MiniGUI timer information and mouse information.Adopt 5 basic object points in screen adjustment program,and value collection of every objection point is divided into multi cursor point's calculation.Through multi-point data collection,comparison and processing,the touch screen can precisely adjust.The result shows that the algorithm can collect more correct value,and less error operations in processing.
