Shuguang Li

Abstract

This article firstly introduces the S3C2440 touch screen driver module briefly, and elaborates the driver design and the realization of resistance-type touch screen after analyzing the principle of the touch screen driver module under Windows CE operating system. And then, the touch screen calibration algorithm, on the basis of the least square, is proposed to improve the precision of calibration.
