Abstract
This paper introduces a ARM-based 32-bit STM32F103VCT6 MCU to design a simple camera. This system consists of ARM-based MCU system, File storage system, Touch screen, DS1302 Clock chip, TFT LCD, and by the main of OV7725 image sensor as a shooting systems unit circuit etc. What the use of the system is the image acquired system which involves a CMOS VGA image sensor of the OV7725 Camera-Chip, and brings about AL422 FIFO data buffer memory using the image data acquired. The core controller with low price , reliable performance and rich peripheral resources of ARM-based MCU. The system press the image sensor acquired image data to FIFO buffer, and the core controller processed image data to display on the TFT LCD or save in the SD card. The study shows that this system has the characteristics of easy to sue, easy and fast, reliable performance. And it can be used some social fields such as entertainment, life, security, etc. In the market economic system, especially in the entertainment and life industry, Using it can be much more saving staffs, that you can not only save money but also meet less troubles.. What’s more, it can improve pany’s efficiency, reduce the cost of production, and bring economic benefits. So it can be used as the electronic product to make development. In my opinion, it has a good value of promotion.
