摘要
选用NXP公司内置LCD控制器的Cortex-M3处理器LPC1788作为主控,设计了一种低成本的液晶触摸屏。介绍了四线电阻式触摸屏与LPC1788的接口设计,移植emWin图形界面库为GUI提供支持。实际运用证明,低成本液晶触摸屏运行稳定,界面设计便捷。
This paper provides a low-cost LCD Touch Screen design which use LPC1788 as the processor.LPC1788 which is de-signed by NXP,is a SoC based on Cortex-M3 CPU and contains a build-in LCD control er,and introduces the interface of 4-wire resistive touch pad with LPC1788.ln addition,transplant the graphical interface library emWin to provide best support for the design of GUl.The practical application shows this screen works stably and makes the interface design convenient.
