主要是对Linux输入子系统的一些简单操作 比如lsinput是看有多少输入设备 比如input-events是看输入设备的键值 用来调试输入子系统很好-Mainly for Linux input subsystem of a few simple operations such as watch lsinput is the number of input devices such as input-events is to look at the key input device used to debug a very good input subsystem

综合比较了嵌入式GUI的几种实现方式，结合嵌入式系统的特点，研究了嵌入式GUI中的关键技术， 分析了嵌入式GUI与普通GUI系统的不同之处，提出一种通用的嵌入式图形用户界面系统的设计思想和体系结构， 这种嵌入式GUI实现方案具有轻型、占用资源少、可剪裁等特点。-Embedded GUI comparing several ways, combined with the characteristics of embedded systems to study the embedded GUI of the key technologies, an analysis of embedded GUI and general GUI systems differ, a general-purpose embedded graphical user interface system design concepts and architecture, the embedded GUI programs realize light, taking up less resources can be cut and so on.

这个是nios核在linux下的应用程序，比较通用，测试过，没有问题。不过没有中断没有使用中断。-This is nios nucleus in an application under linux, more generic, tested, no problem. However, do not use interrupts without interruption.

驱动测试，当驱动写好后，要进行测试，由于嵌入式设备一般使用超级终端或者是telnet进行登录，键盘驱动不是很好测试，我们使用网上开源的libkbd代码进行键盘驱动的测试,下载libkbd后稍加修改既可以在arm-linux上运行。-Driver testing, when the driver after the write, it is necessary to conduct tests, because of embedded devices in general use HyperTerminal or a telnet to log in, the keyboard is not a very good test drive, we use online libkbd code open source keyboard-driven test, download libkbd After a little modification can be in the running arm-linux.
