基于STM32滚球控制系统的分析与设计

Analysis and Design of a Rolling Ball Control System Based on STM32

本设计是基于STM32F407单片机设计的滚球控制系统,本系统主要由图像采集与处理模块、液晶显示屏驱动模块、矩阵键盘模块、电源稳压模块等构成。本系统通过OV2640摄像头采集图像数据以此判断滚球的位置,并结合PID算法来控制调节舵机进而实现小球停在目标位置。为了方便调试和复测,系统采用矩阵键盘的模式。通过对本系统的软硬件的实际测试,其能稳定地运行,到达了预期的目标。

This design is a rolling ball control system based on STM32F407 microcontroller.The system is mainly composed of image acquisition and processing module,LCD driver module,matrix keyboard module,power supply regulator module and so on.It＇s collects image data through OV2640 camera to determine the location of the ball,and combines the PID algorithm to control the steering gear and realize the ball stopping at the target position.In order to facilitate the debugging and retesting,the system adopts the matrix keyboard mode.Through the actual testings of the hardware and software of this system,it can run steadily and reach the expected target.
