摘　　要：随着信息时代的到来,各种各样的嵌入式数字音视频播放系统(如mp3,mp4等)逐渐普及,类似产品往往要求操作简便,使得开发一个高效稳定方便的键盘驱动程序显得非常重要。在基于Power的ml403验证板上,以嵌入式linux为操作系统,以QT-embedded为GUI,对板子自带五方向功能键的驱动程序进行了新的设计及开发,并运用于GUI底层事件驱动。With the advent of the information age, various embedded digital audio and video broadcasting systems（such as mp3, mp4） gradually become widely used. Such products often require simple operation, tile development of a highly efficient, stable and convenient keyboard driver becomes very important. This paper, on the power structure ml403 certification board, used embedded linux as operating system, QT-embedded as GUI, designed and developed a new driver of 5-direction key, which is apphed in GUI event-driven.
