摘要
在嵌入式系统开发中,MiniGUI是典型的图形用户界面系统,触摸屏是常见的输入设备,而输入抽象层作为两者的结合点在人机交互开发中起着重要作用。在分析IAL的数据结构与源代码的基础上,通过修改已有的dummy代码和设置触摸屏控制器相关的寄存器的值,实现了具体的IAL和相关的触摸屏驱动程序,该程序很好地满足了嵌入式应用的需要。
As the joint point of MiniGUI and touch panel, input abstract layer （IAL） plays an important role in human-computer interaction development. The analysis oflAL data structure and source code is presented. Then a concrete IAL and a correlative touch panel driver are designed and implemented by modifiering existent dummy and setting the touch panel register values. These programs meet the need of embedded devices.
