摘要
触摸屏技术经过十几年的发展已经成为一种方便、经济的人机界面输入手段。TSC2046是四线电阻式触摸屏控制器,其核心是一个具有采样和保持功能的12位逐次逼近式A/D转换器。以飞利浦公司的ARM芯片为基础,通过TSC2046触摸屏控制器和四线电阻式触摸屏构成硬件基础,在此基础上,开发了触摸屏面板控制程序。该触摸屏已应用于实际项目中,触摸效果良好。
After a decade of development,touch screen technology has become a convenient and economic mean of human-machine interface input.TSC2046 is a four-wire resistive touch screen controller,whose core is a 12 b successive approximation A / D converter with sample and hold function.In this paper,through the Philips ARM chip,TS2046 touch screen controller and 4-wire resistive touch screen was used to form the hardware base,in this basis,a touch screen panel control procedures was developed.The touch screen with good effect has been applied to actual projects.
