基于STM32的图像动态采集系统 摘 要 随着科技水平的提高， ARM的应用越来越广泛。本论文旨在对ARM的深入学习，论文对?STM32驱动OV7670图像传感器、以及图像在SSD1289驱动控制芯片的显示、以及图片在SD卡上以文件形式的存储和读取进行了初步的探索和研究。 设计过程中多亏了前辈们的刻苦、钻研留下了宝贵的资料。对OV7670的驱动程序的开发，主要是引脚的学习和寄存器的配置，对SD卡图片存储的开发采用的是文件的方式存储，简单地说，就是存储的到SD卡上图片能在电脑上直接打开。期间牵扯到移植文件系统FATFS到STM32上，以前没有这方面的开发经验，主要参考前人的经验。SSD1289驱动程序主要也是一些引脚和寄存器的配置。开发过程中牵扯到STM32的中断向量表的配置等很多基础知识，在图片存储过程中则牵扯到很多存储格式的问题，使问题变得复杂化，最后通过查阅相关资料都一一解决。 经过对STM32开发板和OV7670等芯片的学习，最后实现了图像的动态显示、图片的实时采集、存储和读取。设计过程中碰到了很多问题、一些与课题相关的问题基本都解决了，还有些不属于本论文研究范围的，比如图片的优化显示、清晰度，虽然可以通过驱动程序让清晰度更高，但更多的与芯片本身性能有关，没去做深入的探索和研究。 关键词：STM32，OV7670，SD卡，SSD1289，驱动 Based on the dynamic STM32 image acquisition system ABSTRACT With the improvement of science and technology level, ARM used more widely. This paper aims to further study of the ARM, paper STM32 drive to OV7670 image sensor, and image in the SSD1289 drive control chip of the display, and images on the SD card to file form of storage and read a preliminary exploration and research. The design process of thanks to predecessor, studied hard left invaluable material. To OV7670 driver development, mainly is the pin learning and register configuration, SD card to the development of the storage of the picture is the way file storage, say simply, it is stored to SD card pictures can open direct on the computer. Involved in transplantation during the file system FATFS to STM32, before the development experience, main reference previous experience. SSD1289 driver is primarily some pin and registers configuration. The development process STM32 involved in the interruption of the configuration and many to scale basic knowledge, in the photo storage process is involved in a lot of storage formats, become more complicated, and finally by consulting relevant material all 11 to solve. After the STM32 development board and OV7670 etc chip learning, and finally realize image, the dynamic display of the picture of the real-time data acquisition, storage and read. In the process of design met with
