毕业设计（论文）--基于ARM和Linux的嵌入式数码相框系统设计 毕业设计（论文）--基于ARM和Linux的嵌入式数码相框系统设计 一、背景 随着PC时代数码技术的发展，数码相机以其低廉的价格，方便的操作成为摄影器材未来的发展方向。目前，很多家庭都持有数码相机，一次拍摄下来的照片往往会有上百张，使用PC机来查看拍摄下来的图片，操作繁琐，而且依赖于PC机。 作为数码相机的一种附属产品，数码相框不仅具有传统相框的特点，而且可以直接从数码相机中选择心仪的照片，定时更新照片。数字相框可以摆放在家居显眼之处，成为现代家庭一道靓丽的风景线。 数码相框是展示数码照片而非纸质照片的相框。数码相框直接插上相机的存储卡展示照片数码摄影必然推动数码相框的发展，因为全世界打印的数码相片不到5%。】Embedded system is used as the center, take the computer technology as the foundation, software and hardware can be configured, usually to the function, reliability, cost, volume, power consumption have strict constraints of a kind of special computer system. The current advanced Embedded system, usually by Embedded microcontroller processor,peripheral hardware equipment, Embedded operating system and Embedded application four parts, real computer based on ARM Linux and Qt/Embedded Embedded digital photo frame system research and implementation application system, called the Embedded system, real-time systems or Embedded real-time system. According to the current domestic and foreign research and development of embedded, combining with the condition of experiment, this project use hardware platform embedded software public technology center of guangdong province the development of GEC2440 development board as the target machine, use Windows XP install the PC as the host machine, and in the host machine Windows platform installed a virtual machine software, virtual machine is installed, the Red Hat EnterpriseLinux 5 as a development environment. Main realization work include: in the host machine installation cross-compiling tools, set up cross-compiling environment, the configuration TFTP, DNW or super terminal to establish embedded software platform. A can browse pictures and management function, and can play a course design slides. For the project requirements to achieve the perfect for drivers and transplantation, making for the development of the board root filesystem, finally will be based on qt app
