【摘要】 随着嵌入式系统的发展,用于实现与用户交流功能的嵌入式GUI成为研究中的一个重点。嵌入式Linux下,如果图形界面接口采用的是Qt/Embedded,则必须采用Linux的帧缓冲设备来处理相关的底层命令。帧缓冲是Linux为图形设备提供的一个抽象接口,是Qt/Embedded的底层图形引擎。文中介绍了Linux帧缓冲设备驱动程序框架,基于三星公司的S3C2410x处理器的开发平台,系统给出了嵌入式图形界面GUI的移植,包括编译环境的建立,编译参数的设置等。更多还原

【Abstract】 With the development of embedded system,embedded GUI which is used to communicate with users has become a key in researching the embedded system.If GUI such as Qt/Embedded is used,the Linux framebuffer device must be implemented to process low level commands.The framebuffer device provides an abstract interface for the graphics hardware,which is the foundation of Qt/Embedded graphics engine of low level.Introduces the framework of the Linux framebuffer device drivers and the transplantation of embedded GUI under the platform of Samsung’s S3C2410x processor,including the establishing of compiling environment,configuring and modifying of compiling parameters.更多还原
