摘 要推出平板的目的是为了弥补手机和笔记本电脑之间的这块空白区域，就是为人们提供一款和手机一样携带方便、操作简单，但比手机视觉效果更好，并能像笔记本电脑一样可以快速流畅的上网、观看视频和玩游戏的产品。软件方面，除苹果自己有自己的 IOS 外，不管是国内还是国外厂商，由于 google 的开源，基本都选择了 andriod 操作系统作为开发平台。Android 是一个基于linux 内核的操作系统，在一款产品的开发过程中，硬件驱动程序的开发和调试是一项艰巨的任务，驱动程序的质量直接影响产品的性能和稳定性，所以对平板上驱动程序的讨论和设计具有实际工程意义。此次设计针对平板电脑中常用的几个硬件驱动进行了讨论和设计，如 LCD 驱动，PWM 背光驱动，按键驱动等。旨在熟悉驱动设计流程，掌握驱动设计的一般方法。关键字：平板电脑,Android,linux，硬件驱动ABSTRACTThe purpose of the launch of the tablet is in order to make up the piece of blank area between mobile phones and laptop computers for people to offer a device as easy as mobile phone to carry, simple to operate, but better than the mobile phone visual effects, and the same as the laptop can quickly access to the Internet, watching videos and playing games. On the software side, in addition to Apple's own IOS, whether domestic or foreign manufacturers, because of google opened the android source code, basically choose the andriod operating system as the development platform. Android is a Linux kernel-based operating system, in the process of a product development, developing and debugging hardware drivers is an arduous task, the quality of the driver directly impact on product performance and stability, So the research and design of the driver on the Tablet PC has a practical engineering significance. This paper will research and design a few hardware drivers that commonly used in the Tablet PC, such as LCD drivers, PWM backlight driver, key drivers and so on. The purpose of...
