嵌入式系统液晶显示器的尺寸和分辨率种类很多,操作系统也各不相同,造成嵌入式软件运行于不同嵌入式系统时,其显示程序必须重新编写.针对采用Windows CE不同衍生版本的嵌入式系统,提出在设计通用化显示界面的基础上,采用基于分辨率检测的自适应显示方法解决上述问题,并给出了界面设计原则、程序流程和自适应显示计算方程.该方法能够实现同一程序在不同嵌入式系统中的自适应运行,大大减少软件设计工作量.其原理还可应用于其他嵌入式操作系统的显示程序设计.
An adaptive displaying method is proposed for the software interface of embedded system based on liquid crystal display (LCD). The characteristic of different derivate versions of Windows CE is analyzed. An adaptive displaying method based on display resolution detecting is proposed, the equations and process is given. Based on this method, one program can run in the embedded systems with different displayer. The method can greatly improve the program efficiency of embedded software based on Windows CE. This method can also be applied in other embedded operating systems.
