简易数码相框与电子书阅读器的设计

摘要

基于嵌入式系统的数码相框与电子书阅读器的开发已成为电子产品领域的一个热点，为了更好地满足人们对于多媒体娱乐的需求，提出了一种简易数码相框与电子书阅读器的设计。该设计采用速度更快，内存更大的STM32单片机作为主控制器，利用FAT32文件系统的管理，成功地实现了从SD卡中读取bmp图片文件和txt文档，并能在TFT液晶屏上显示的功能。该设计成本低，体积小，便于携带，具有很好的娱乐功能。%The development of digital photo frame and e⁃book reader based on embedded system has been a hot issue in the field of electronic products. In order to meet the multimedia entertainment needs of people better,a design scheme of digital photo frame and e⁃book reader is proposed in this paper. This design can read BMP format images and txt format documents,as well as display them on a TFT screen by making use of FAT32 file system management and taking high⁃speed and large memory STM32 single chip microcomputer as its main controller. It has the characteristics of low cost and small size,and is easy to car⁃ry. Thus it has better entertainment functions.
