摘要
介绍了利用μC/GUI在使用S3C44B0处理器的嵌入式系统中的触摸屏控制方法,并讨论了触摸屏控制器ADS7843的工作原理,以及与μC/GUI的连接技术,提供了一种简单有效的去除触摸屏抖动的方法,给出了在S3C44B0下触摸屏的编程方法,重点分析了μC/GUI的使用及其与触摸屏协同应用时所遇到的问题及解决方法,并给出了具体实例,以及引入μC/OS II嵌入式操作系统进行优化的方法。
The touch-screen control method via μC/GUI in S3C44B0 embedded system is introduced in detail in it. The elements of ADS7843 touch-screen controller and its interface with μC/GUI are discussed. In addition, a simple and effective method to eliminate jitter of touch-screen is provided. The programming of touch-screen based on S3C44B0 is also proposed.Furthermore, it analyses problems and puts forward their solution in the co-application of μC/GUI and touch-screen. At the end, an example and its optimizing method using μC/OS Ⅱ embedded operating system is offered.
