摘要
为人机界面中触摸屏的接口设计与驱动控制提供了一种解决方案,在介绍四线电阻式触摸屏工作原理的基础上,详细阐述了嵌入式微处理器(S3C2410)与触摸屏模块之间的硬件接口与驱动实现,并利用S3C2410的等待中断模式和自动X/Y坐标转换模式,实现了X/Y坐标的确定,完成对触摸屏的控制。测试结果表明,该触摸屏系统稳定可靠,能够达到预期效果,可应用于各类通用嵌入式产品中。
This paper provides a solution for the hardware interface design and driver control of touch screen. On the basis of introducing the principle of touch screen, the hardware interface between 83C2410,touch screen and driver implementation are expatiated in detail. And the X/Y coordinate are ready by using waiting for interrupt mode and auto X/Y position conversion mode, the control of touch screen is completed. Test results show that the touch screen system is stable and reliable,be able to achieve the desired performance,and can be applied to all types of general-purpose embedded product.
