摘要
基于C8051F040单片机,详细讲述了四线式电阻触摸屏与单片机的电路连接及基于此硬件系统的"三点法"校准触摸屏的方法。系统分为单片机模块,LCD显示模块及四线式电阻触摸屏模块。在安装或使用过程中,LCD与触摸屏之间容易产生较小的机械偏差,利用程序校准后的系统能够很好地显示触摸的内容。
The system is based on C8051F040 MCU. The circuit connection between :four-wire resistive touch screen and MCU is introduced in detail, and the "three-point method" to calibrate the touch screen based on this hardware system is also introduced. The system is divided into MCU module, LCD module and four-wire resistive touch screen module. When installing or using the touch screen, a small mechanical error can be produced easily between LCD and touch screen. The system after calibration procedures can be a good indication of the contents of the touch.
