基于ARM的触摸屏控制 摘要：本文介绍了基于ARM的触摸屏控制的设计思路、原理和实现方法。硬件电路主要由PHILIPS公司的ARM7TDMI-S微控制器LPC2290，FM7843控制器和SID13503控制器构成。利用C语言编写驱动和用户程序，通过触摸屏的FM7843控制器将触摸信号进行A/D转换，进而利用ARM芯片和彩色液晶屏SID13503控制器，将触摸动作在液晶屏上进行显示，最终实现了触摸屏和液晶屏的控制。该设计操作直观、简单、功耗小、提高了人机交互的友好性。关键词：触摸屏; 液晶屏; ARM The Control of Touch-screen Based on ARM Abstract: This paper introduced the designing of thought and the achievement methods of the control of ARM touch-screen based on ARM.
