【摘要】：电子白板系统改变了传统的教学模式,运用当代的多媒体和显示技术,具有功能丰富、操作简单等优点；嵌入式技术是将先进的计算机技术、半导体技术和电子技术与各个行业的具体应用相结合的产物,因其具有内核小、专用型强、可裁剪等优点而得到广泛应用。本文正是将上述两种技术结合到一起,设计一种基于嵌入式的电子白板系统。 本文在分析了电子白板系统和嵌入式系统基本概念及特点的基础上,提出了基于嵌入式的电子白板系统的组成结构,并对其硬件和软件部分进行了详细的设计。硬件部分,主要对S3C2400A核心处理器、存储器模块、音频模块、网卡模块、显示模块及电源模块进行了设计。软件部分,首先利用Visual C++6.0工具完成了在Windows平台下软件功能的开发,包括整体界面和框架的设计,图元对象显示、选取、变换、保存等各种操作的实现,适合教学平台的图片资源的引入、音频播放等功能的实现；其次详细分析了Windows CE操作系统的特点及架构,定制了适合硬件平台的操作系统,包括BSP(板级支持包)的开发、系统工程的建立、内核的编译及SDK(软件开发包)的导出,并利用该环境下的应用软件开发工具Embedded Visual C++4.0实现电子白软软件的移植同时添加相关的驱动程序；最后对系统进行测试,显示运行效果良好,符合预期目标。
[Abstract]:The electronic whiteboard system has changed the traditional teaching mode, using the modern multimedia and display technology, has the advantages of rich function, simple operation, etc. Embedded technology is the advanced computer technology, Semiconductor technology and electronic technology combined with the specific applications of various industries have been widely used because of their advantages of small core, strong specificity, tailoring and so on. In this paper, the two technologies are combined to design an embedded whiteboard system. On the basis of analyzing the basic concepts and characteristics of electronic whiteboard system and embedded system, this paper puts forward the structure of electronic whiteboard system based on embedded system, and designs its hardware and software in detail. In the hardware part, the S3C2400A core processor, memory module, audio module, network card module, display module and power module are designed. In the software part, the software function is developed by using Visual C 6.0 tool, including the design of the whole interface and frame, the realization of the display, selection, transformation, saving and so on. Secondly, the characteristics and architecture of Windows CE operating system are analyzed in detail, and the operating system suitable for hardware platform is customized, including the development of BSP (Board level support package). The establishment of the system engineering, the compilation of the kernel and the export of the SDK (Software Development package), and the application software development tool Embedded Visual C 4.0 under this environment is used to realize the transplantation of electronic white soft software and the addition of related drivers. Finally, the system is tested, which shows that the running effect is good and accords with the expected goal.
